WATER HEATERS & VALVES
Pressure reducing valve service in Roswell
Pressure reducing valve service in Roswell and North Metro Atlanta. Street pressure can run higher than your pipes, faucets and water heater are built for. The PRV at the main brings it down to a number the house can live with. When the valve fails, you get banging pipes, dripping faucets or no pressure. Tell us what the taps are doing. Call 770-597-4141.
Signs you need pressure reducing valve service
- Pipes bang or hammer when a faucet or the washer shuts off.
- Faucets and the toilet fill valve started dripping around the same time.
- Pressure swings from a blast to a trickle during the day.
- The relief valve on the water heater keeps letting water out.
- Low pressure everywhere with the main valve fully open, so call before buying parts.
How we diagnose it
- 1Measure before replacing anythingWe measure the pressure coming in and watch it over time. The number tells us whether the valve is doing its job, stuck, or not there.
- 2Rule out the other causesLow pressure can be a supply-line leak or a clogged fixture. High pressure can be the valve or no valve at all. We check the system, not just the part.
- 3Set it for the houseA new or adjusted valve is set to what your plumbing and water heater need, then tested at the taps. You get the setting and the price in writing.
Your likely options
- Method
Adjust the existing valve
What it doesA working valve set too high or too low is brought to the right pressure and checked again under flow. No parts, no cutting.
When it applies- the valve holds pressure and responds to adjustment.
- Method
Replace the valve
What it doesA valve that will not hold a setting, leaks at the body or has seized is cut out and a new one installed at the main and set.
When it applies- a failed valve, or one that drifts after every adjustment.
- Method
Install a valve where there is none
What it doesSome houses never had one. If incoming pressure runs above what the plumbing is built for, a PRV goes in at the main line where water enters the house.
When it applies- high measured pressure and no valve on the service line.
What it costs
A visit to look at the problem. We tell you on the phone, before we schedule, whether that visit has a charge and what it is.
- Adjustment, replacement, or a first-time installation.
- Where the main enters and how much pipe has to change.
- Whether the expansion tank or heater valves need attention too.
A written scope and price for the repair, before we start. No work beyond that scope without your OK.

Pressure reducing valve service questions
Is low pressure always the valve?
No. A leak on the supply line, a half-closed valve or a clogged aerator drops pressure too. We measure first, so you do not buy a valve for a leak.
Will a new valve stop my faucets dripping?
It stops the pressure that is wearing them out. A faucet that has already failed still needs its own repair. We tell you which fixtures need work after the pressure is right.
Is the PRV the same as the expansion tank?
No. The PRV lowers the pressure coming in from the street. The expansion tank absorbs the pressure the water heater creates inside. A house can need one, both or neither.
Do you charge to come out and look?
We tell you on the phone, before we schedule, whether the visit has a charge and what it is.
How soon can you come?
Call and we tell you straight; it depends on the day. For an active leak or backup, call rather than sending the form.
