Water Valve Repair & Replacement in Tucson, AZ
Valves that actually work when you need them.
Seized, dripping, or missing shut-off valves turn a small repair into a flooded room. Priority Rooter & Plumbing repairs and replaces main valves, angle stops, hose bibs, and mixing valves with quarter-turn hardware built for Tucson's hard water.
Valve won't shut off and water is running?
If you can't stop the flow at the fixture, shut your main water valve or call us right away. We respond 24/7 to isolate the leak and replace the failed valve.
Every valve in the house.
From the meter to the last fixture — repaired, replaced, or added where one was never installed.
Main Water Valve Replacement
Seized or leaking main shut-off valves replaced with quarter-turn ball valves you can trust.
Angle Stop Replacement
Fresh quarter-turn stops under sinks and toilets so future repairs never require killing the whole house.
Leaking Valve Repair
Drips at the stem, packing nut, or compression fitting corrected before they damage cabinets and floors.
Gate to Ball Valve Upgrades
Old multi-turn gate valves swapped for reliable quarter-turn ball valves that don't seize.
Water Heater Supply Valves
Heater shut-off and drain valve replacement — a must before any tank service or replacement.
Hose Bib & Sillcock Valves
Outdoor faucet valves repaired or replaced, including frost-resistant sillcock upgrades.
Irrigation Valve Work
Manual and zone isolation valves for drip and sprinkler systems repaired and replaced.
Mixing & Tempering Valves
Thermostatic mixing valves adjusted or replaced to keep hot water safe and consistent.
Softener & Filter Bypass Valves
Bypass and isolation valves at treatment equipment so service doesn't shut down the house.
Add Missing Shut-Offs
New isolation valves installed at fixtures and branches that never had one.
Commercial Isolation Valves
Riser, branch, and mechanical room valve service for rentals and commercial buildings.
Emergency Valve Service
Can't shut your water off? We respond 24/7 to isolate the line and replace the valve.
Test your valves before you need them.
Most valve failures are discovered during an emergency. These signs show up much earlier.
The handle won't turn
A stuck handle means scale has locked the stem. Forcing it usually snaps the valve open.
Drips when you turn it
Water weeping from the stem or packing nut means internal seals are gone.
Water still flows when closed
A valve that won't fully seat is worse than none — it gives you false confidence in an emergency.
Corrosion or green crust
White scale or green corrosion on brass means the valve has been seeping for a long time.
No valve at the fixture
If a toilet or sink has no local stop, any repair means shutting off the whole house.
You've never tested them
Valves that haven't moved in ten years usually don't move at all. Exercise or replace them.
Quick, clean, and low-downtime.
Most valve work is done in a single visit with only a short water shut-off.
Inspect & test
We check every accessible valve, confirm which ones hold, and identify what's missing.
Explain your options
Repair vs. replace, and which upgrades will save you money on future service calls.
Flat-price quote
You approve one clear price before we touch a fitting.
Isolate & replace
Water is shut off, the failed valve is removed, and a new quarter-turn valve is installed.
Pressure test
We restore water, check for weeps under full pressure, and verify each valve closes fully.
