Water Pressure Problems and Valve Replacement in Gwinnett County
Water pressure that runs too high wears out every fixture in the house, and pressure that runs too low means weak showers and slow-filling tubs. 1st Place Plumbing measures your pressure, finds the cause and corrects it with the right valve, across Gwinnett County and metro Atlanta. Call or text (770) 800-7563 or book online to schedule service.

What we can help with
- Pressure reducing valve replacement: When the valve fails, pressure climbs and fixtures start failing early.
- Main shut-off valve replacement: A quarter-turn ball valve you can close in an emergency, instead of one that won't budge.
- Stop valves under sinks and toilets: Old stops seize or weep, and replacing them takes minutes.
- Backflow prevention: The devices that keep outside water from being drawn back into the house.
- Whole-home pressure diagnosis: We find out whether the problem is the valve, the meter or the lines themselves.
What to expect
We put a gauge on an outside faucet and read the pressure at the house. If it's above the safe range, the pressure reducing valve has usually failed and we replace it. If it's low, we look for a failing valve, a partly closed shut-off or a restriction in the line, and we test rather than guess. Either way you get the reading and the explanation before we quote anything.
You need the main shut-off valve to close when something goes wrong. If yours is stiff, corroded or won't seal, we replace it with a quarter-turn ball valve. Before we leave, we make sure you know where it is and how to close it.

Frequently asked questions about water pressure & valves
What should my water pressure be?
Between about 50 and 70 psi for most homes, and never above 80. The pressure reducing valve is what sets it. We measure yours and tell you where it stands.
Why do my pipes bang?
Usually high pressure or a failing pressure reducing valve, and sometimes a pipe that has worked loose in the framing. We measure the pressure first and go from there.
Can you fix low pressure at just one faucet?
Yes. Pressure that's low at one fixture and fine everywhere else is usually the fixture or its supply line, not the whole house.
