Water Heater Service Built for Mobile and Manufactured Homes
We provide mobile home water heater repair in Apache Junction, AZ and Gold Canyon, for mobile homes, manufactured homes and park models. Under HUD rules, gas units in manufactured homes must be models listed for manufactured-home use, and many sit in a closet reached from outside. We work within those limits and your park's rules, 24/7.
About 46% of the homes in Apache Junction are mobile or manufactured homes, many in the parks along the Apache Trail, Delaware Dr, Ocotillo Dr and Meridian Rd (see leak repair in west and central Apache Junction) and the communities off Idaho, Tomahawk and Royal Palm (see east-side leak repair). Their water heaters have the same basic parts as any other, but almost everything around them is different: the space, the access door, the venting, the floor and the rules.
What Makes Mobile Home Water Heaters Different
HUD-listed models for gas units
Gas water heaters in manufactured homes must be models listed for manufactured-home use. Listed units are usually sealed-combustion designs that draw their air from outside the living space, which is why a standard store-shelf gas heater isn't a straight swap, even if it fits.
Outside-access closets
Many heaters sit behind a small exterior door. That keeps combustion outside the living space, but it also exposes the closet to summer heat, monsoon rain and the occasional freeze.
Floors that don't forgive leaks
Mobile-home floors are often particleboard or thin wood decking. A slow leak can swell and soften them, and the damage spreads under walls and cabinets.
Smaller tanks, tight spaces
Common sizes run about 20 to 40 gallons, gas or electric. Height and diameter matter as much as capacity, because the closet door has to close and the vent has to line up.
Can I put a regular water heater in a mobile home?
For gas, generally no. Gas water heaters in manufactured homes must be models listed for manufactured-home use. Electric models are less restricted, but size, wiring and the closet layout still have to work. When we handle a water heater replacement in a mobile home, we match the listing, the dimensions and the connections before anything is installed.
Gas or electric for a mobile home?
Stay with what you have unless there's a clear reason to switch. Electric units need no venting and are simpler to place. Gas units recover faster after heavy use but must be the right listed type with correct venting. Switching fuel adds wiring or gas line work, which adds cost and normally needs a permit. Our Apache Junction water heater permit rules page explains when.
Common Mobile Home Water Heater Problems in Apache Junction
- Drain valve leaks. Hard water, about 13–16 grains per gallon here, leaves sediment that stops plastic drain valves from sealing. A brass replacement is usually the fix. See drain valve leaking.
- Relief valve drips. With July highs around 105°F, hot outside closets wear T&P valves faster. On-and-off discharge while the tank heats usually means thermal expansion, which an expansion tank handles. A steady drip points to a worn relief valve.
- No hot water after storms. Monsoon outages (June 15 to September 30) can trip the reset or breaker, and surges can damage thermostats or elements. Check the breaker first. To press the reset, turn the breaker off, open the panel, press the button, close the panel and turn the breaker back on. If it trips again, call us, or see no hot water repair.
- Cracked lines on freeze nights. Winter lows average about 42°F but have dropped into the high teens. Exposed lines in older outside closets can split.
- Pilot outages. Wind and dust can affect pilots in outside closets, and worn thermocouples are common on older units.
- Rusted-through tanks. Many older mobile-home heaters have never been flushed. Once the tank leaks, it must be replaced. See water heater tank leaking.
My floor feels soft near the water heater. What should I do?
Stay off the soft area, shut off the cold-water valve to the heater, and turn off the breaker or set the gas control to "Off" or "Pilot." Take photos for your insurance company (see what insurance usually covers). When you call us, mention the soft floor so we can check it before any new heater goes in. A full tank weighs several hundred pounds and needs solid support, which is where replacing a rotted platform or pan comes in.
Working in Mobile Home Parks and RV Resorts
Many parks have rules about contractor access, parking, work hours and who may work on park-owned equipment. Tell us your park's name when you call. Most mobile home water heater repair in Apache Junction, AZ happens inside a park, so we plan around those rules and the visit goes smoothly for you and your neighbors.
- Let your park office know a water heater visit is coming, if your park asks for that.
- Check whether the water heater belongs to you or to the park, especially in rentals.
- Clear a path to the outside closet door, including plants or stored items.
Do you service park models?
Yes, and our park model water heater repair page covers them in detail. Park models usually have small gas or electric water heaters in very tight spaces. We repair and replace them, and we leave the area clean and dry.
Snowbird Homes: Leaving for Summer and Coming Back
Apache Junction roughly doubles to about 80,000 people each winter, and many of those homes are mobile homes that sit closed up all summer. An outside closet nobody opens for six months is where a slow drip turns into a soft particleboard floor.
Before you leave, shut the cold-water valve and turn off the heat, and have someone look in the closet now and then. Our printable snowbird water heater checklist lists every step, or book our snowbird close-up and start-up service and we'll handle both visits.

Mobile Home Water Heater Repair Apache Junction, AZ: FAQs
What size water heater does a mobile home usually have?
Most fall between about 20 and 40 gallons, gas or electric. Park models often have the smaller end. The replacement has to fit the closet's height and width and line up with the existing water, gas or electric connections. The label on the tank lists its size and fuel.
Do mobile home water heaters cost more to replace?
Gas ones often do. Gas units must be models listed for manufactured-home use, which narrows the choice. Tight outside closets, venting and floor repairs can also add labor. Electric models are often simpler to replace. Angi's Apache Junction average to install or replace a water heater is about $1,136 (typically $819–$1,320), and listed gas models plus closet work can push a mobile home job higher. Our replacement cost guide breaks it down.
Can a mobile home water heater be in an outside closet?
Yes. Many are installed in a closet with an exterior door, which is common in Apache Junction. The closet still needs proper venting for gas units, a working relief line and protection from freezing on cold nights. Keep the door clear of stored items so the heater gets air and is easy to reach.
Does a mobile home water heater closet need a drain pan?
It's a good idea wherever the closet has room. A pan with a drain line catches drips before they reach particleboard, which swells and softens fast. Some tight outside closets only fit a shallow pan, and the line has to run somewhere safe. If the floor is already soft, we repair the support first. See stand and drain pan replacement.
The park owns my water heater, or I rent my lot. Who handles a leak?
First, find out who owns the heater. If you own the home on a rented lot, the heater is usually yours, but the park may set rules on who can work there. If the park owns the heater or the home, tell the park office right away; they decide on repairs. Shut the water off either way. This isn't legal advice.
Do you work in Gold Canyon parks and resorts too?
Yes. We serve mobile homes, manufactured homes and park models in Apache Junction ZIP codes 85119 and 85120 and in Gold Canyon's 55+ and resort communities. See our service areas for the full list. Tell us your park or resort name and lot number when you call.
Why does the outside door on my mobile home's gas water heater closet have vents?
Those louvers or openings usually give the burner the air it needs. Don't cover or seal them, even to keep out cold or dust. A burner short of air burns poorly, can put out the pilot and can make carbon monoxide. To protect against freezing, insulate the exposed lines instead. If the vents are rusted or blocked, call +1 480-863-0807 and we'll check the closet.
