Water pressure problems are a common plumbing issue. Figuring out what is causing the problem is the first step. In some cases, it’s a simple fix. In other cases, it may not be so simple.
Here are some common causes of household low water pressure:
Mineral Deposits and Other Blockages
Old iron pipes may have rust that breaks loose, causing particles to plugs up valves, aerators, valve and other areas within the pipes. Mineral deposits can also clog faucets and shower heads, restricting water pressure.
If your sink faucet isn’t working well, try removing the aerator (the small cylinder screwed on the end of the spout) and see how the water flows without it. If the water flow is better without the aerator, clean or replace it. If your shower has a low water flow problem, remove the shower head and then check the water pressure.
If the water flow is still poor after removing the aerator or shower head, then the source of the problem is elsewhere in the plumbing system.
Blockages or mineral buildup may create low water pressure problems. If small mineral deposits accumulate on insides of your plumbing system, it reduces the diameter through which the water can flow. You may need to regularly descale and remove sediment buildup. If your area has hard water, installing a water softener can help reduce the problem.
Water pressure regulators (also called pressure reducing valves or pressure limiting valves) are designed to reduce incoming water pressure and to protect a home’s plumbing system components. The pressure regulator is usually found below the hose connection in the front of your home, though it may be in different places. If the pressure regulator goes bad or malfunctions, it may cause low water pressure issues. This is a plumbing repair problem best left for a professional.
Well Water Pressure
Homes that use well water use a water pressure tank. These tanks can sometimes leak and lose water pressure. You may need to increase your tank pressure setting to 40/60 psi. This one adjustment may solve the problem.
The flow rate of your well pump may be too low to meet your demand. Upgrading to a different well pump with a higher flow capacity should greatly increase your home water pressure.
a water pressure booster pump to your home plumbing system.
A water pressure booster pump can help, especially if the water pressure on the top floor of your home seems lower than on the ground floor. Booster pumps are motors that increase the flow of water throughout your home.
If you have low water pressure problems, you can try to fix the problem on your own. However, issues of pipe corrosion, major blockages or major water leaks are all problems better left to professional plumbers.
