Low water pressure
Start by figuring out whether it's one faucet, all the hot water, or the whole house. That narrows the cause quickly.
One faucet or showerhead
Unscrew the aerator or showerhead and soak it in vinegar to clear mineral buildup. Middle Tennessee water is moderately hard, so this is common.
Only the hot water
Sediment in the water heater, a partly closed valve on the heater, or a failing mixing valve can cut hot water flow. A plumber can flush the tank and check the valves.
The whole house
- Make sure the main shutoff valve is fully open, especially after recent plumbing work.
- Ask a neighbor or check with your water utility for work or main breaks nearby.
- If your home has a pressure reducing valve where the water line enters, it may have failed. A plumber can test the pressure and replace it.
- A hidden leak can also drop pressure. Turn off every fixture and watch the water meter. If it still moves, call a plumber.
Older homes with galvanized steel pipes can lose pressure as the pipes corrode inside. Repiping fixes that for good.
