Water Valves You Can Count On

Hard Arizona water leaves scale that seizes valves over time, so many homeowners discover their shut-off doesn’t work in the middle of an emergency. We replace main shut-offs, fixture stops, pressure-reducing valves (PRVs), and thermostatic mixing valves so you are always in control of your water.

Arizona Tip

Many Valley homes have water pressure above 80 PSI. A properly set PRV protects every fixture and appliance in your home.

Signs You Need Help With Water Valves

  • Valve won’t turn or won’t fully shut off
  • Banging pipes or very high water pressure
  • Leaks at the valve stem
  • Fluctuating shower temperature

I called about my sewer backing up, and they came out within the hour and took less than an hour to fix it. Very friendly, very efficient, cleaned up after themselves and I would definitely use them again!
Patricia H.Phoenix, AZ★★★★★
Our water heater died on a 112 degree day. Baja had a new one installed by dinner. Upfront price, no surprises, and the tech walked me through everything.
Marcus T.Mesa, AZ★★★★★
My plumber was excellent. They scheduled me the same day in the afternoon. I could not have asked for a better plumber.
Brian A.Chandler, AZ★★★★★

I highly recommend Baja Plumbing. Very efficient. I called in the morning and they came out in the afternoon and solved the problem. Extremely professional.
