What Can Cause Fluctuations in Water Pressure?

What Can Cause fluctuations In Water Pressure

Sometimes your water pressure is too strong; sometimes it’s barely more than a trickle. If the water pressure in your home is fluctuating and all over the place, you may be confused as to what’s causing the problem. Pressure may change in the same outlet over time, or you may have different pressures in different parts of the house. To get to the bottom of the issue of changing water pressure, it’s important to look at the potential causes.

Air Trapped in Pipes

When air gets trapped in pipes, it can cause fluctuating, and spluttering water pressure as the air and water move through the pipes. Air trapped in pipes acts as a valve, causing water flow to stop and start in fits and bursts. Air can enter the pipes through a leaking suction line, damaged tank bladders, a faulty pump, gas build up in the well system or leaks in the pipeline.

Pressure Regulating Valve Failure

The pressure regulating valve is designed to manage and stabilize main water pressure as it enters a home’s plumbing system. Pressure regulating valves are usually installed to counteract mains water pressure that’s too high. However, if the pressure regulating valve fails or malfunctions, water pressure may suddenly increase or fluctuate between too high and too low. Check the pressure regulating valve yourself by lifting and lowering the test lever, or get an inspection from your local plumber, Magnificent Plumbing if you think this may be the cause of your issues.

Clogged or Old Pipes

If the plumbing system in your home or the mains pipes supplying your home are many decades old, chances are they may be clogged, constricted, and filled with debris. As pipes leak or clogs move around inside the pipes, water pressure can vary and fluctuate. If your plumbing system is old and has potential issues and leaks, it’s essential you have it inspected and potentially replaced as soon as possible. Even small leaks can cause significant damage and wastage, whereas a burst pipe can cause flooding and an expensive renovation. If the issue seems to be with your mains supply, you’ll need to speak with your local water authority.

Municipal Water Supply Issues

If the municipal water supply is affected, your home supply will be affected too. Leaks, damage, and clogs in the mains supply line will pass on to your supply too. Water supply can also be redirected in times of drought, or your pressure may be diminished due to a fire hydrant being used somewhere on your line. If you’re concerned about fluctuating water pressure that seems to be caused by municipal line problems, call the city authorities about water supply in your area.

High Usage of the Same Line

Even high water usage on the same main line as you, such as neighbors filling a pool or using water for landscaping can cause the pressure in your supply to go up and down. Stay up to date with your neighbors’ water usage to understand how your supply might be affected.

Fluctuating water pressure should be investigated and corrected as soon as possible. Talk to your local plumber, Magnificent Plumbing for expert advice in addressing and correcting water pressure issues.
