Water Pressure Repair in Fort Worth, TX

Low or high water pressure? The signs

Low pressure

• Weak flow, or a washer, dishwasher or toilet tank that fills slowly
• Flow that drops when a second fixture runs
• Pressure that faded over months, or dropped suddenly

High pressure

• Pipes that bang when the washer or dishwasher shuts off (water hammer)
• Toilet fill valves that hiss, run or keep failing
• Repeat leaks at supply hoses, or a dripping water heater relief valve

Check your water pressure in five minutes

1. Turn off all water use, inside and out.
2. Thread a pressure gauge onto a hose bib or the laundry faucet and open it fully.
3. Read it. About 40 to 80 psi is normal; under 40 feels weak and over 80 is high.
4. Open a nearby faucet. A big drop points to a restriction like scaled pipe or a partly closed valve.

What causes low water pressure in Fort Worth homes

One fixture

If only one faucet or shower is weak, look at that fixture: a clogged aerator or showerhead, a worn cartridge or a partly closed stop valve. Fort Worth's hard water leaves scale in these parts (see faucet, shower or fixture repair). Weak hot water at several fixtures points to the water heater.

The whole house

Weak pressure everywhere points to a failing PRV, a main or meter valve that isn't fully open, a leak, or buildup in old pipe. If the neighbors lost pressure too, call Fort Worth Water; the main is their side. After a main break, like the June 2026 break that put the Northside 2 pressure plane under a boil notice, stirred-up debris can clog aerators and screens.

Pressure that faded over years: galvanized pipe

Galvanized steel supply pipe is still common in Riverside, Oakhurst, Six Points and Fairmount, where many houses date from the 1920s–60s. It scales shut from the inside, so pressure fades slowly, often with brown water. No valve adjustment fixes that; replacing the worst sections, repiping or a new service line does (see water line repair).

A hidden leak

A leak in the yard line or under the slab steals flow before it reaches your taps, and North Texas expansive clay keeps stressing buried pipe. A meter that moves with everything off calls for leak detection or slab leak repair.

Pressure-reducing valve (PRV) repair and replacement

A PRV is a bell-shaped brass valve on the main line, usually near the main shut-off, in the garage or in a box near the meter. It steps street pressure down to a steady level. Street pressure varies with elevation across Fort Worth Water's pressure planes, so some homes need a PRV and others have none.

Signs a PRV is failing:

• Pressure that creeps higher over days or weeks
• A sudden drop across the whole house
• Surging while you shower, or a valve that hums or leaks

Sometimes it only needs adjusting or its strainer cleaned. If it can't hold a setting, we replace it and set the new valve to a safe working pressure, under the 80 psi limit most plumbing codes set for homes.

Thermal expansion: a PRV can stop heated water from expanding back toward the street, so pressure climbs each time the water heater runs. An expansion tank on the heater's cold supply is the usual fix.

How our water pressure repair works

1. Test static and flowing pressure, before and after the PRV where we can.
2. Check the valves and look for leaks: main shut-off, meter, fixture stops, the PRV and the water heater.
3. Explain the fix before work starts, then retest at your fixtures.
