When you're ready to choose a tap or shower, you'll find the water pressure it's suitable for will be clearly labelled.
What is water pressure?
Water pressure refers to the measure of force to get water through the mains and into your pipework. It is measured in “bars”, where one bar is the equivalent to the force required to push water up to the height of 10 metres.
What does it mean when water pressure is 100 psi?
Call your water company if you notice that your water pressure is immensely above the normal standards. When the force exceeds 100 psi or more, this could indicate a problem in the water supply network. It’s the supplier’s responsibility to make sure that your home receives normal levels of water so if you feel like it’s too high it is worth getting in contact with them to see if anything can be done.
What is the difference between water pressure and water flow?
As we discussed above, water pressure is the measurement of the force that it takes to get water through your mains and into the pipework of your home.
Why is water pressure weaker on a hill?
So if you live on top of a hill, for example, your water pressure is likely to be weaker as the water is fighting against gravity to reach your house. On the other hand, if you live at the bottom of a hill, your water flow is likely to be much stronger because gravity is helping to pull it down the hill to your property.
Can low water pressure cause a weak shower?
It’s not something we think about often, but making sure your water supply has the correct water pressure could make or break the water function in your home. If your home suffers from low water pressure it will be painfully obvious to see, your taps in your kitchen and bathroom will produce a weak dribble while your power shower will be reduced to gentle rain.
Can a pressure reduction valve be used for high pressure water?
Fitting a pressure reduction valve could also help with your high-pressure water problems. For a novice at DIY, it may be advised to get the help of a professional to install it for you as it can be quite tricky to do if you don’t know your way around the pipework.

How much pressure does a water supply have to be?
Your water supplier must be able to supply a statutory 1 bar of normal mains water pressure (enough pressure to move water vertically to a height of 10 metres). This should be measured at the point that pipework enters your property, for example at the boundary of your property.
Why is water pressure weaker on a hill?
If you live atop a hill, your water pressure is likely to be weaker than someone whose home is situated at the bottom of a valley, simply due to how quick the flow will be to that destination. Uphill = Flow is weaker as it works against gravity. Downhill = Flow is stronger as gravity aids it. To get an idea of how this affects your mains water ...
What is water pressure?
Water Pressure is nothing but the flow of water from the pipe. It is defined as the force which makes the water flow stronger or weaker. Here are the simple and easy steps to calculate the water pressure.

What does bara mean in a gauge?
Sometimes, “Bar (a)” and “bara” are used to indicate absolute pressures and “bar (g)” and “barg” for gauge pressures.
What is absolute pressure?
Pressure as discussed above is called absolute pressure. Often it will be important to distinguish between absolute pressure and gauge pressure. In this article the term pressure refers to absolute pressure unless explicitly stated otherwise. But in engineering we often deal with pressures, that are measured by some devices. Although absolute pressures must be used in thermodynamic relations, pressure-measuring devices often indicate the difference between the absolute pressure in a system and the absolute pressure of the atmosphere existing outside the measuring device. They measure the gauge pressure.
What is the cause of pressure or the force exerted per unit area on the boundaries of a substance?
In general, pressure or the force exerted per unit area on the boundaries of a substance is caused by the collisions of the molecules of the substance with the boundaries of the system.
