What's included
What's Included in Shut-Off Valve Repair
Every shut-off valve job covers the essentials: diagnosis, water shutoff, valve replacement or rebuild, pressure testing, and cleanup. Here's what you get, and where add-ons like flange or wax ring work come in.
✓
Full Valve Diagnosis
We shut off the main, drain the tank, and inspect the valve body, stem, packing nut, and supply line connection. An inspection camera checks for hidden moisture in the wall. You get a straight answer on whether to rebuild or replace, with pricing for both.
✓
New Quarter-Turn Valve
We install a quarter-turn ball valve rated to 200 PSI, matching your supply line size. It closes in one quarter-turn, so future repairs take seconds. We carry valves compatible with Kohler, American Standard, Toto, Gerber, Moen, Delta, and Sloan fixtures.
✓
Supply Line Replacement
If your supply line is old, kinked, or cracked, we replace it with a braided stainless line while the valve is out. That's the combo that prevents most toilet floods. Most Phoenix jobs include this at no extra labor cost.
✓
Pressure Test and Leak Check
We restore water, open the new valve, and watch it under full house pressure for five minutes. We check the supply line, tank inlet, and floor around the flange with a dry paper towel. If anything weeps, we fix it before we leave.
✓
Flange and Wax Ring Inspection
While the toilet is pulled, we check the flange for cracks and the wax ring for failure. If either needs replacing, we quote it upfront and handle it on the same visit. That saves you a second call-out and a second water shutoff.
✓
Cleanup and Walkthrough
We wipe down the fixture, haul away the old valve and line, and walk you through what we did. You get a written workmanship warranty and a two-minute lesson on exercising the valve twice a year to keep it from seizing.
How it works
How Our Shut-Off Valve Repair Works
01
Phone Diagnosis
You call +1 (602) 835-0160 and describe what you're seeing: a stuck handle, a drip at the wall, or water that won't stop. We ask three or four questions, give you a price range on the spot, and book a same-day window. Most Phoenix calls get a technician out within two to four hours.
02
Shut Off and Inspect
We kill the water at the main, drain the tank, and pull the toilet supply line. Then we inspect the valve body, stem, and packing nut, plus the toilet flange and wax ring while we're in there. An inspection camera checks for hidden moisture in the wall cavity. Ten minutes, no charge for the look.
03
Replace or Rebuild
If the valve body is sound, we rebuild it with a new stem, washer, and packing nut for less money. If the body is cracked or the seat is scored, we cut it out and sweat in a new quarter-turn valve. Either way takes 30 to 60 minutes, and we use an adjustable wrench, putty knife, and torch with a flame shield.
04
Pressure Test
We restore water, open the new valve, and watch it under full house pressure for a solid five minutes. We check the supply line connection, the tank inlet, and the floor around the flange with a dry paper towel. If anything weeps, we fix it before we call the job done.
05
Clean Up and Walkthrough
We wipe down the fixture, haul away the old valve, and walk you through what we did. You get a written workmanship warranty and a plain-English explanation of how to exercise the valve twice a year so it never seizes again. Total visit time: 60 to 90 minutes on most jobs.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Adjustable Wrench and Basin Wrench
Used to break loose the compression nut and valve body in tight spaces behind the toilet. A basin wrench reaches where a standard wrench can't, which saves the wall from getting chewed up.
Inspection Camera
Slides behind the wall to check for hidden moisture, corrosion, and cracked fittings around the valve. It's how we confirm a drip hasn't already rotted the subfloor before we close everything up.
Propane Torch with Flame Shield
Used to sweat copper when we cut out a seized valve and solder in a new one. The flame shield protects the wall and framing. Most copper replacements take 30 to 45 minutes.
Quarter-Turn Ball Valves
Rated to 200 PSI and built to resist hard-water scale. We stock sizes to match standard supply lines. These close in one quarter-turn, so future repairs take seconds instead of a trip to the main.
Braided Stainless Supply Lines
Replaces old plastic or corroded copper lines that crack under Phoenix heat. Braided stainless handles pressure spikes and lasts years longer. We install them with every valve replacement when the old line is suspect.
Fluidmaster and Korky Rebuild Kits
Contain the stem, washer, and packing nut needed to rebuild a sound valve body for less than a full replacement. We use them when the body is intact and only the internals have failed.
Real results
Before and after.
Seized Valve in a 1955 Encanto Bungalow
Before
The homeowner couldn't turn the shut-off valve by hand, and a wrench just rounded the handle. The valve had been frozen for years, and the supply line was original galvanized pipe with visible corrosion at the wall.
After
We cut out the seized valve, sweated in a new quarter-turn ball valve, and replaced the galvanized stub with copper and a braided stainless line. Total job time was 75 minutes. The valve now closes in one quarter-turn, and the wall connection is dry.

Before

After
We rebuilt the valve with a new stem and packing nut, replaced the supply line with braided stainless, and used an inspection camera to confirm the wall cavity was still dry. The drip stopped, and the baseboard dried out within a week. Total cost was $265.
