4 Causes of Low Water Pressure

Low water pressure is a problem that seems to follow you around your house. The showerheads emit a weak spray and sink faucets slow to a trickle. Each one a frustrating reminder that there is a problem. If you don’t know where the problem starts, it is so difficult to get moving towards a solution. Here are some possible causes of low water pressure in your home.

Faulty Regulator

The pressure regulator is a control valve that reduces the input pressure in your plumbing system to a safe level that will not damage your pipes. When the regulator fails, you might notice changes and inconsistencies in your water pressure or loud banging pipes from pressure surges called water hammering. If you do decide to change anything with your regulator make sure you shut off your water main first so that nothing is damaged.

Leaks

Water leaks can cause low pressure because not all of the water is making its way to your faucet. By the time you need it at the faucet, maybe only a few drops are left. Luckily there is a pretty simple way to see if not all of your water is getting where it needs to go. All you have to do is check your water meter, which is usually found near the curb or sidewalk in front of the property. Don’t use any water for an hour and check it again. If the meter indicates continued water use, you have a leak.

Hard Water

Hard water is simply water with high mineral content. Deposits from hard water cause weaker water pressure. Particles of limestone or chalk can build up inside of your pipes, constricting the flow of water. While this water is perfectly safe to drink and use, it can eventually lead to pressure issues. The solution here is a water softener.

Corrosion

Corrosion can lead to a similar problem. Rust and other minerals can form clogs that drastically reduce the pressure. Older homes may have galvanized pipes that carry a higher risk of corrosion. Unfortunately, often the only solution is to do a full repiping of the water system when there is strong corrosion.
