Dealing with low water pressure can be frustrating. It makes everyday activities such as washing dishes and taking a shower such a hassle. Some causes of low water pressure can be minor, while others require the expertise of a professional. If you have low water pressure and are troubleshooting what’s causing it, here are some common reasons listed below.
FAULTY PRESSURE REGULATOR
The pressure regulator is typically located where your local supply line connects to your home, right after your home’s main shut-off valve. It controls the water pressure coming from your service line into your home. A licensed plumber can inspect the pressure regulator and determine if this is for sure the cause.
SCALE BUILDUP
Minerals and other sediment can buildup in pipes, especially in older homes, causing a reduction in water flow. If your plumbing is corroded or blocked and needs replacing, this is a job for a licensed plumber.
CORRODED PIPES
Corrosion is a common cause for homes with older plumbing. Galvanized steel pipes can start to corrode in as few as 20 years, while copper and PEX can last around 100 years with continual use. You’ll want to have a plumber inspect your pipes before committing to such a big project.
LEAKY PIPES
Leaky or damaged pipes can be another cause of low water pressure. Check around your valves, toilets, sinks, and other plumbing fixtures to see if water is spilling out. If you do discover a water leak, shut off the water outlet valve on the wall and contact your local plumber.
CLOGGED AERATOR
Faucets and showerheads have aerators to regulate how much water comes out. They look like small mesh screens. Unscrew the aerator from the faucet, clean it, and see if that improves your water flow.
SEDIMENT IN YOUR WATER HEATER
Sediment build-up in your water heater can also cause low water pressure. Keeping up with your yearly water heater service and flushing can ensure all components are working properly and help prevent it from impacting your water pressure.
