Common Problems that Result in High Water Pressure
Published in Blog, 31st Oct 2014
Water pressure is defined as the force that pushes water through the pipes. At the end of the day, it’s the same pressure that will determine the flow from your taps. If the pressure is low, the speed at which water flows from the taps reduces so it takes longer to fill a kettle. If the pressure is high, the speed of flow increases.
Problems Leading High Water Pressure
Causes of Variations In Water Pressure In the Home
The amount of pressure at your tap basically depends on two things; how much other customers on the same line are using and the other is how high the tower or the service reservoir is.
You will agree that when everyone in the neighborhood has their taps turned on then the pressure on each tap will significantly reduce because you’re sharing the same reservoir and the same delivery lines. That’s why pressure is normally higher late in the night when other people are sleeping and therefore their taps are closed. The early morning is usually marked with very low pressure because everyone is using it in one way or another.
The height of your house may also affect the pressure – for example, properties at the top of a raised area (such as a hill)will may experience lower pressures compared to properties at the foot of the hill.
High Water Pressure In the Home
High water pressure is when water in your pipes is flowing at an abnormally high speed. The municipal water supply pressure for example sometimes runs quite high; in some cases even as high as 150-psi. This is dangerous and must be reported to the relevant authorities (in this case the municipal offices) as soon as possible. According to most national and local building codes, the maximum static pressure should not exceed 80psi which is equivalent to 5.5-bar.
- Was the high pressure offset by a past maintenance work?
If you’ve had supply interruption in the recent past, particularly for maintenance reasons, there is a possibility that the high pressure could be caused by air trapped in your pipes. It may help to run your taps for several minutes as release the trapped air.
- Was the water supply network re-configured?
Pressure changes can also be caused by a reconfiguration of the supply network. Re-configuration simply means moving the water around to places where it is needed and sometimes comes with a change in supply routes. This should be a temporary problem; all you have to do is call your supplier.
- Could it be that you’ve not adjusted to life in your new home?
If you’ve just moved homes, it is possible that you’ve not adjusted to the pressure levels in the new home. Turn the internal stop tap down slowly as you check the pressure until you arrive at a level that you’re comfortable with.
- Is the pressure reducing valve set too high?
One of the simplest ways of fixing high water pressure is to install a pressure reducing valve. The valve helps to bring the pressure to safe levels before it reaches pipes and other plumbing fixtures in your house. However, setting the pressure reducing valve can also cause high pressures in the home. For this reason, it is advisable to hire a professional plumber to fix the valve.
If the high pressure problem is persistent, don’t hesitate to call your supply company.
