Water pressure is a very important factor in maintaining a comfortable and functional home. Adequate water pressure is essential for everyday activities such as bathing, cooking and cleaning. Homeowners often take water pressure for a home granted until issues arise, impacting their daily routines.

Low water pressure in a house can have broader implications, and potentially affect the overall value of a property. Buyers are increasingly discerning, and aspects that contribute to a home’s liveability, including water pressure can influence their purchasing decisions.

In the context of the UK property market, where housing trends and buyer preferences evolve, understanding the impact of low water pressure on property values becomes important as part of multiple issues that affect house prices.

At the end of the day, low water pressure in a house isn’t going to devalue a property significantly, but it could be used to negotiate a better deal from prospective buyers.

What do homebuyers expect from water pressure?

Homebuyers usually expect a reasonable and consistent water pressure when purchasing a new property. The water pressure in a home can significantly impact the comfort and convenience of daily activities.

Homebuyers expect sufficient water pressure to perform everyday tasks seamlessly. This includes activities like showering, washing dishes, doing laundry, and filling up baths. Bad water pressure in a house can be a source of anger and frustration.

Consistency is key with homebuyers, as they desire balanced water pressure across all faucets and mixers in the house. Uneven pressure or significant variations between different areas of the home can be seen as a flaw. The shower experience is a priority for many homebuyers as they expect strong and consistent water pressure in the shower to enhance the bathing experience.

Prospective buyers appreciate transparency regarding any known water pressure issues. Sellers are generally expected to disclose information about the water system, including past problems and any remedies implemented.

Should I buy a house low water pressure?

Just because a house has a low water pressure, doesn’t mean you shouldn’t buy it. Low water pressure systems can be improved and they can be manageable. However, while low water pressure in a house itself may not be a deal-breaker, it’s important to assess the extent of the issue, potential causes and the feasibility of improvements.

You will need to assess how severe the low water pressure is throughout the house, and work out if it’s a minor inconvenience or a significant hindrance to your daily routine. Low water pressure in house should be identified during any house surveys that have taken place.

Before making a decision, you should use the findings of a survey report to identify the cause of the low water pressure, which commonly stems from clogged water pipes, plumbing system inefficiencies or local water supply problems. Understanding the root cause may help determine the complexity and cost of potential solutions.

The costs of repairing the low water pressure systems could be factored into negotiations when purchasing a property, and may allow you to purchase below the true market value, if the water pressure is deemed a severe issue.

Why should you find out the water pressure of a house?

If the water pressure is too low to perform everyday tasks like washing up or having a bath, you may become extremely frustrated. On the flip side to this, if your water pressure is too high it could increase the risk of leaks, burst pipes and flooding.

When considering a property with low water pressure, savvy homebuyers can use this as a negotiation point during the purchasing process. The costs associated with repairing low water pressure systems could potentially be factored into negotiations offering a strategic advantage for the buyer.

Here is how knowing the water pressure could help you out with negotiating:

  1. Strategic negotiations:Low water pressure in a house is a legitimate concern that affects the liveability of a home. During negotiations, buyers can leverage this issue to negotiate a lower purchase price. Sellers, aware of the problem, may be motivated to sell the house and accommodate a reasonable reduction in price.
  2. Cost estimates:Before entering negotiations, it’s essential for buyers to obtain cost estimates for repairing or upgrading the water pressure system. Armed with this information, they can present a clear case for a reduction in the property’s price, ensuring that the negotiated amount reflects the anticipated repair costs.
  3. Home survey contingency:Including home survey contingency in the purchase agreement is a smart move. This allows buyers to thoroughly assess the property, including its water pressure systems, with the option to negotiate or even withdraw from the deal if the issues are more extensive than initially anticipated.

What are the effects of low water pressure on home use?

Buyers often associate low water pressure in house with outdated infrastructure and it can create a negative perception of the overall quality, safety and maintenance of the property.

Low water pressure can impact functionality and convenience within a property, as the low water pressure in a house can result in a weak water flow, which can diminish the quality and capability of showers, baths, dishwashers, washing machines and any garden irrigation systems you may need.

In addition to inconvenience, low water pressure can lead to potential damage such as inefficiency flushing toilets and water supply for fire sprinkler systems.

Is knowing the water pressure of a house really that important?

Understanding the water pressure of a house is a very important aspect when evaluating its overall functionality and long-term sustainability. Here are a few key reasons why prospective buyers should find out the water pressure of a house:

Daily convenience

The water pressure directly impacts the daily activities within a home. If the pressure is too low, common tasks such as washing dishes or clothes can become frustrating and time-consuming.

Avoiding frustration

Bad water pressure in a house can lead to considerable frustration for homeowners. Knowing the water pressure beforehand allows buyers to assess whether the property aligns with their expectations and lifestyle preferences.

Preventing potential damage

If the water pressure is too high, it can pose risks such as leaks, burst pipes and potential flooding which may cause you thousands of pounds to fix later down the line.

Maintenance and longevity

A property with well-maintained and optimised water pressure systems is likely to have a longer lifespan. Understanding the current state of water pressure infrastructure provides insight into the property’s overall maintenance.

Insurance considerations

Some insurance providers may take into account the condition of a property’s plumbing problem. Knowing the water pressure can assist in obtaining accurate insurance coverage and potentially avoiding complications in the future.

Understanding water pressure

Water pressure is the force exerted by water molecules as they move through a plumbing system or any enclosed space. In the UK, water pressure is measured in Bars and one Bar is enough to push water upwards, known as static head, to 10 metres. One Bar in the UK, is the equivalent of 14.5 PSI (Pounds per Square Inch) in the US.

Here are some factors that influence water pressure in a home:

  • Plumbing infrastructure:Older or poorly maintained plumbing systems may contribute to low water pressure in a house.
  • Local water supply:The water infrastructure in a given area, including the supply from municipal sources, can impact pressure.
  • Water conservation measures:Efforts to conserve water, such as low-flow fixtures, may inadvertently reduce water pressure.

From taking a satisfying shower to efficiently running household appliances, sufficient water pressure is integral to numerous daily tasks.

How does water pressure work?

Water pressure is a variable aspect of household plumbing, presenting significant differences from one home to another, even within different rooms of the same household, and fluctuating at various times throughout the day.

The primary determinant of mains water pressure is the geographical relationship between your residence and the nearest water source, such as a reservoir. If your home is perched on a hill, it is likely to experience weaker water pressure compared to a home nestled in a valley.

The distinction arises due to the gravitational influence on the water flow: uphill locations encounter a weaker flow as it contends against gravity, while downhill homes benefit from stronger flow facilitated by gravity.

Beyond geographical factors, water pressure is not static and can be influenced by the demand for water within your community. For instance, during peak hours between 7 and 9 in the morning, you may experience reduced water pressure as fellow residents engage in activities like bathing and showering.

Similarly, warm summer evenings might bring about a decline in water pressure due to increased demand for watering gardens and why occasionally the Government will introduce hose bans in order to conserve water.

What is the legal minimum water pressure?

In the UK, your water supplier has to supply a mandatory 1 Bar of water pressure, which should be measured at the point the water pipework enters your property boundary.

How do you test water pressure in your home?

Testing water pressure in your home is a pretty simple process that you can perform using a water pressure gauge, and plumbers will do this as part of their working routine.

In order to test your water pressure you will need to purchase a water pressure gauge from a hardware or gardening store. Before starting the test, it is highly recommended that you ensure that all water-using appliances, taps and showers inside your home are turned off. This guarantees an accurate measurement of the incoming water pressure.

You will need to choose a tap or mixer that is directly connected to the main water supply to ensure that you are measuring the pressure entering your home. If there are any hoses or adapters connected to the chosen outlet, you should disconnect them to ensure a direct connection with the water pressure gauge.

Next attach the water pressure gauge to the chosen outlet using the provided hose or threaded connection and ensure a tight and secure fit to prevent any water leakage during the test.

Turn on the tap or outlet fully, allowing water to flow into the gauge and activating the needle to indicate the water pressure. Make note of the measurement displayed on the water pressure gauge, this will usually be in Bars, but may also be in PSI.

For accuracy, repeat the process at different times of the day and create an average of the scores provided.

What is the difference between water flow and water pressure?

Water pressure is the force exerted by water against the walls of pipes, fixtures or closed systems. It is the measure of force that propels water through the plumbing system. Think of it as the strength with which water is pushed through the pipes.

Water flow on the other hand refers to the volume of water passing through a specific point in the plumbing system within a given time period. It is a measure of how much water is moving through pipes or outlets, expressed as litres per minute.

If water pressure is the force, water flow is the quantity, providing insight into the rate at which water is delivered to faucets, showers or other points of use.

How do you test your water flow rate?

In order to gauge the efficiency of the plumbing system, here is a step-by-step guide to measuring your water flow rate:

  1. Get a one or two litre water jug and a stopwatch.
  2. Place the jug beneath your bathroom tap or shower, turn on the tap and let the water flow into the jug.
  3. Time six seconds using your stopwatch and then turn off the water.
  4. Calculate the flow rate by multiplying the amount of water collected in the jug (in litres) by 10.

If your flow rate is below 10 litres per minute, it may indicate low water pressure. A flow rate between 10 and 15 litres per minute is acceptable but can be improved. A flow rate exceeding 15 litres per minute is considered good and reflects strong water pressure.

Why is the water pressure low in my house?

One of the most common causes of low water pressure in a house is the external water mains valve not being fully open, which restricts the flow of water and therefore the water pressure. This is obviously easily fixed and can be done without the help of a plumber.

What is the most common cause of low water pressure?

Identifying the root causes and implementing effective solutions is essential for restoring optimal water flow in your home.


Pipe leaks

In order to identify an external pipe leak, you should turn off the main stop tap for water inside the building, take a water metre reading and compare it after a few minutes. An increase suggests an external leak. You will need to contact your service provider for guidance on resolving external leaks.

Pressure is just low

If your water pressure is consistently low despite addressing internal issues, it may be a system or external supply problem. You can explore installing a pump to improve the water pressure based on your system, heating and pump placement.


Obstructed stop valves

In order to identify an internal obstructed stop valve, you will need to check that the main water supply valve to the building is fully open. If it’s not fully open, maximise water pressure by ensuring the valve is fully open.

Narrow pipes

Older homes may have narrower pipes, causing low water pressure, especially during simultaneous use of multiple outlets. Resolving this issue requires fitting some or all of the affected pipes, a complex task which should be left to plumbers.

Blocked pipes

Blocked pipes, due to limescale, rust, dirt or debris can lead to an increased water pressure that then drops off to a reduced water flow. Consult a plumber for advice on using water softeners or replacing sections of blocked pipes.

Blocked taps and showers

Build-ups of limescale, rust, or debris can restrict water flow from taps and showers. Hot water outlets are far more likely to become blocked over a period of time. Remove blockages by flushing out pipework during renovations, or replacing your taps and shower head.

Low pressure showers

In cases of consistently low pressure, especially for showers, consider a power shower designed for low-pressure systems. Power showers use electric pumps to boost water flow, providing a more enjoyable shower experience. While more expensive, they are designed for low-pressure situations.

What If I have low water pressure in my house?

If you are experiencing low water pressure in house, it can be frustrating at times. However, there are steps you can take to identify and address the problem.

The first thing you should do is check whether there are any local water supply issues, which can be done by asking your water supplier if there is any ongoing work or repairs. You may also want to ask your neighbours if they are experiencing similar issues. If the decreased water pressure in a house issue is widespread, it may be a community-wide concern.

If you feel as if your low pressure is isolated to your home, you may want to inspect your property for any visible leaks and ensure that all your valves are fully open – partially closed valves can reduce your water flow and pressure. Failing this, read below.

How can you fix low water pressure?

Homeowners can perform basic checks for leaks, blockages or faulty pressure regulators but you may need to upgrade your plumbing fixtures which we recommend should be completed by a trained plumber.

The first step in addressing water pressure concerns is understanding your home’s water system. If you’re unsure about your system type, it should have been included in the properties information when you purchased it. If you can not find it this way, then you can get a plumber to come round and check instead.

For Combi Boiler Systems, to improve your low water pressure you should confirm that your stop tap is fully open. Sometimes, a partially closed stop tap can restrict the water flow and affect the water pressure.

Alternatively, you should check if any pressure-reduction systems are set to the statutory minimum level of 1 bar. Adjusting these settings can optimise water pressure.

For gravity fed systems, you should consider asking a plumber to install a shower pump that can significantly enhance water pressure. These pumps, available for purchase around £180, work to boost the performance of both showers and taps.

Even if your mains water pressure is decent, a shower pump can take your water pressure to the next level, ensuring a more satisfying shower experience.

How can you use power shower pumps to increase water pressure?

Power shower pumps can significantly enhance the water pressure in UK homes, especially in situations where the existing water pressure is low or inconsistent.

Power shower pumps are designed to amplify the water pressure in your home’s plumbing system. They do this by taking the existing water flow and increasing its pressure before it reaches your shower head. This results in a stronger, more consistent flow of water, which can be particularly beneficial in homes that suffer from low water pressure.

Can high pressure electric showers increase water pressure?

High-pressure electric showers are a popular solution in the UK for increasing water pressure, especially when the existing water pressure is low.

High-pressure electric showers have a built-in heating element and an independent pumping system. This means they do not rely on the water pressure of your home’s hot water system. Instead, they take in cold water and heat it as it passes through the unit, while the integrated pump boosts the water pressure.

These showers are particularly suitable for homes with low water pressure. Since they have their own pumping mechanism, they can significantly increase the pressure of the water coming out of the shower head, regardless of the pressure in the rest of the house.

High pressure electric showers can be easier to install compared to other systems that increase water pressure, like power shows, as they don’t require a separate hot water supply. They only need a connection to the cold water mains and an electrical connection.

When should you hire a plumber to fix the water pressure in your home?

If you have never fitted a shower pump before, we would recommend hiring a plumber to fit one, but you can ask them to show you how to do it for the future.

If you continue to have bad water pressure in a house, we would recommend getting a plumbing professional to conduct a comprehensive assessment of your system, identify any underlying problems and recommend tailored solutions to improve its water pressure.

What if there is no water pressure at home?

The first port of call when you think there is no water pressure in your home is to speak to your water company.

If it is not a supply issue then you should check your water supply metre to see if there is water entering your property. If this shows you are receiving water but yet you have no water pressure then you may want to speak to a plumber or get a survey of your property.

This could be a sign that a water pipe has burst, and you may be at risk of flooding.

How do you decrease water pressure in house?

Most modern homes are equipped with a pressure reducing valve (PRV) which is installed where the main water line enters the house. This valve can be adjusted to reduce the pressure of the water coming into your home.

Turning the adjustment screw or knob on the valve can lower the pressure, but it’s important to do this gradually and check the pressure with a gauge to avoid setting it too low.

If your home doesn’t already have a PRV, you can have one installed. This is especially useful if the high pressure is due to the municipal water supply being at a high pressure. A plumber can install a PRV to ensure that the pressure is reduced to a safe and manageable level inside your home.

Sometimes, high water pressure is a result of a faulty pressure regulator. These regulators are designed to maintain a constant pressure level, but they can fail over time. Replacing or repairing a faulty regulator can resolve issues with high water pressure.

Partially closed valves can sometimes cause pressure buildup in the system. Ensure that all valves, especially the main shutoff valve, are fully open, as a partially closed valve can create pressure increases downstream.

Does low water pressure decrease house value?

Not directly, low water pressure won’t cause a massive decrease in house valuation however it may have a degree of influence on the amount of negotiation power a potential buyer has. Low water pressure in a house may create a negative impression on potential buyers as it can be perceived as an inconvenience and may raise concerns about the overall condition of the plumbing system.

Homes with good water pressure are often considered more attractive and appealing for potential buyers, and some buyers may be willing to pay a higher price for higher water pressure in a low water pressure area.

Low water pressure could be used as a negotiation point during the home buying process as buyers may seek a reduction in the selling price to compensate for the inconvenience.

But, sellers who address and resolve the low water pressure issue before listing the property may be able to mitigate its impact on the perceived value. Upgrades to plumbing systems or the installation of pressure-boosting equipment can be seen as positive improvements.

The impact of low water pressure on house value can also be influenced by the overall conditions of the local housing market. In a competitive market, some buyers may be more forgiving on minor issues.

Sellers are generally required to disclose known issues, including those related to water pressure. Providing transparency about the steps taken to address the problem can build trust with potential buyers.

While low water pressure may affect the immediate marketability of a property, addressing and improving the issue can contribute to its long-term value and selling potential.
