RV Water Heater Repair
No hot water at the campsite is a quick way to end a trip early. We come to your rig and get it back, most jobs the same day. Mobile water heater repair (gas, electric, and tankless) for Suburban, Atwood, and Dometic across the Tampa Bay area.

What we fix
Gas, electric, or combo (tank or tankless, Suburban or Atwood): every RV water heater fault diagnosed on-site and fixed same-day when we can.
Cold at every tap, a failed element, thermostat, gas valve, or tripped reset, traced from the tap to the tank.
Clicks but won't light, or lights and drops out, a burner, igniter, thermocouple, or gas-valve fault.
The electric side's dead, usually a burned-out element, a bad thermostat, or a tripped high-limit reset.
Water under the heater or at the fittings, a cracked tank, a failed drain plug, or a loose connection.
Discolored or rotten-egg hot water usually means a spent anode rod, a cheap swap that saves the tank.
Left in bypass after winterizing, or a seized bypass valve, no hot water until it's cleared.
Seeing something that's not on the list? We've almost certainly fixed it before.
Tell us what's happeningWhat's included
Gas, electric, or combo, we diagnose the real fault (element, thermostat, igniter, gas valve, anode, or bypass) and repair it on-site, plus flush and service the tank while we're there.
When a tank's cracked or rusted through, we replace it, or upgrade you to an on-demand tankless heater for endless hot water and less weight. We'll walk you through the trade-offs before you spend.
Good to know
Most RV water heaters run two ways (propane and 120-volt electric), and knowing which side failed points straight at the fix. If the electric side is dead, it's almost always a burned-out heating element, a bad thermostat, or a tripped high-limit reset button. If the gas side won't work, it's usually the igniter, the thermocouple, or the gas valve: the burner clicks but won't stay lit. Many owners never realize one side quit because the other keeps making hot water. We test both, so you leave with everything working, not just the half you noticed.
Suburban (and some Dometic) steel tanks have a sacrificial anode rod: a soft metal rod that corrodes on purpose so your tank doesn't. When it's used up, the tank starts to rust, the hot water smells like rotten eggs, and eventually it leaks. Swapping the anode rod once a year and flushing the tank is one of the cheapest, highest-value bits of RV maintenance there is. (Atwood tanks are aluminum and use no anode, worth knowing which you have.) If you've got smelly or rusty hot water, that's the rod talking; we'll swap it and flush the tank.
When a tank heater dies, a tankless (on-demand) upgrade is tempting, and often worth it. Tankless gives you effectively endless hot water, saves weight, and frees up the space a 6- or 10-gallon tank takes. The trade-offs: it needs decent water flow and pressure to fire, the temperature can swing if you crack the tap too low, and it costs more up front. For a lot of full-timers it's a clear win; for weekend campers a straight tank replacement is often the smarter money. We install both and we'll tell you which fits how you actually camp.

“I was caught in a jam at the KOA campground in St. Petersburg when my air conditioner unit was throwing a faulty code. After calling multiple people, Jared assured me he would be there as soon as possible to help since it was so hot outside. Jared showed up within 20 minutes of the call and had the issue fixed in less than that. He was professional, knowledgeable, and was fair with his pricing!”
