RV Water Heater Repair in Tucson, AZ
No hot water, a pilot that won't stay lit, or water pooling under the RV — Shawn repairs Suburban and Atwood water heaters on-site, tank and tankless, gas and electric, without you towing the rig anywhere.
Most RV water heaters fail in one of three ways: the pilot or igniter won't stay lit, the tank leaks from a corroded anode rod or cracked tank, or the water runs lukewarm instead of hot because a heating element or thermostat has failed. Each points to a different fix, and none of them require replacing the whole unit unless the tank itself is cracked.
Suburban and Atwood are the two brands installed in the overwhelming majority of RVs on the road, and Shawn is factory-trained and vendor-certified on both — including the DSI (direct spark ignition) control boards that cause a lot of the 'won't light' calls he gets.

Pilot lights, then goes out
Usually a weak thermocouple or sail switch — a common repair, not a sign the tank needs replacing.
Water is warm, never hot
On electric-mode units this usually points to a failing heating element; on gas mode, a partially clogged burner orifice.
Water dripping from the pressure relief valve
A small drip is often just excess tank pressure venting normally; a steady leak from the tank body itself usually means a corroded anode rod or a cracked tank.

Frequently asked questions
Yes — including dual-mode (gas/electric) Suburban and Atwood units, tank-style and tankless.
No. If the leak is from a fitting, the anode rod port, or the pressure relief valve, that's a repair. A leak from a crack in the tank body itself does mean replacement.
On Suburban tanks with an anode rod, checking it once a season (more often with Tucson's hard water) catches corrosion before it causes a leak — Shawn can check and swap it during any service call.
Yes, including on-demand/tankless systems — diagnosis for ignition faults, flow sensor issues, and descaling from hard water.
