A weak shower or a slow-filling sink is more than an annoyance. It can be a clue that something in your plumbing needs attention.
Maryland homeowners can use this guide to work through eight common causes and learn when low water pressure repair is the better next step.
1. A Partly Closed Valve
WSSC Water lists partially closed main or fixture valves among the causes. A valve that is not fully open restricts flow. Check that your main shut-off valve is fully open first.
2. Clogged Fixture Screens
Fixture screens can clog too. If one faucet runs weak, unscrew the aerator and look for debris. If the faucet is worn out, new faucet installation may be worth considering.
3. A Failing Pressure Regulator
A pressure-reducing valve keeps pressure in a safe range. The EPA WaterSense program recommends 45 to 60 psi. If the valve malfunctions, pressure can drift outside that range. The same sheet notes that too much pressure can damage pipes, fixtures, and appliances.
4. Corroded or Restricted Pipes
Restricted pipes can cut flow. Old lines made of deteriorating material, such as galvanized steel, may need replacement, and copper can corrode over time from utility water treatment.
5. Hidden Leaks
Water lost through a leak never reaches your fixtures. Low pressure throughout the entire house can be a warning sign of a failing water line.
6. A Public Supply Problem
If low flow shows up throughout the property, WSSC Water says to call it. The utility will test pressure at the nearest fire hydrant and at your property. Homes served by another utility can call that provider.
7. Dry-Weather Well Trouble
If you have a well, sputtering faucets and a sharp drop in supply can follow dry conditions. Pump size and depth matter too. We note that a properly sized system delivers 10 gallons per minute with a 1/2 horsepower motor.
8. A Faulty Pressure Tank
On a well system, a faulty pressure tank or a tripped pressure switch can limit pressure. Check that the pump is plugged in and the breaker has not tripped before calling.
Need Low Water Pressure Repair?
WSSC Water suggests checking with a plumber when only one fixture is affected, or restricted pipes are the likely cause. We can trace the problem and explain your options, whether the cause is a valve, a regulator, or a pipe.
