Who repairs park model water heaters?
Apache Junction Water Heater Pros handles park model water heater repair and replacement in RV resorts around Apache Junction and Gold Canyon. Most have a small electric tank or an RV-style gas/electric unit, often 6 to 20 gallons, in a tight closet or behind an outside door. We fix leaks, no-heat problems and failed tanks, 24/7.
Park models are the small, permanent-looking homes you see in many of the RV resorts along the Apache Trail and Idaho Rd, and along US 60 out in Gold Canyon. They're typically up to about 400 square feet, often with a porch or an add-on room. Many belong to winter residents who come for the season and leave in spring.
Because the space is so small, the water heater is too. That changes how it fails, which parts fit, and how the work gets done.
How is a park model different from a mobile home?
They look alike from the street, but they're built to different rules. A manufactured home is built under the federal HUD code, and gas water heaters in those homes must be models listed for manufactured-home use. A park model is built as a type of RV, so its plumbing and water heater often look more like what you'd find in a travel trailer than in a house.
| Feature | Park model | Manufactured (mobile) home |
|---|---|---|
| Size | Typically up to about 400 sq ft | Usually much larger, single or multi-section |
| Built to | RV-type standards | HUD code |
| Common water heater | 6–20 gallon RV-style or small electric tank | About 20–40 gallon gas or electric |
| Typical location | Small closet, under a cabinet, or behind an outside access door | Closet reached from outside, or inside utility closet |
If you live in a manufactured home rather than a park model, our mobile home water heater repair page covers HUD-listed models, outside closets and soft floors in more detail.
What kind of water heater does a park model have?
Three main types are common in the resorts around town:
Small electric tanks
Compact tanks, often 10 to 20 gallons, tucked into a closet or under a counter. Simple to work on, but slow to recover after a shower.
RV-style gas/electric units
Built into an outside wall with an access door. Many run on propane, electric or both, and hold about 6 to 10 gallons. If the unit was bypassed when it was closed up, set the bypass valves back to normal before filling, or no water reaches the tank.
Larger tanks in add-ons
Some owners have added a bigger home-style tank in a shed or utility room on the lot. Those follow house rules more than RV rules.
Why does my park model run out of hot water so fast?
A 6 or 10 gallon tank only holds a short shower's worth of hot water. If it used to last longer, sediment may be taking up space in the bottom, an element may have failed, or a dip tube may be broken. With our 13–16 grain water, the same amount of sediment takes up a bigger share of a small tank.
Can a park model have a bigger water heater?
Sometimes, if there's room and the wiring or gas supply can handle it. A bigger tank often won't fit the closet, though, and moving or upsizing usually means a permit and park approval. Tankless is another option for some lots, and our tank vs tankless guide for Arizona compares the two. We'll tell you plainly what fits.
Common park model water heater problems
- Leaking drain plug or valve. Small tanks often have a plastic drain plug or valve that cracks or won't seal over sediment. See our page on a water heater drain valve leaking.
- Relief valve drips. An outside-wall compartment in July sun ages the valve on an RV-style unit. These small tanks rely on a little air space at the top, and once it's gone, a bit of weeping as the tank heats is common. A steady drip means a worn valve; see why a relief valve leaks.
- No heat after a storm. After a monsoon outage, check the breaker and the reset first. RV-style units also have their own electric switch, and the gas side runs off a 12-volt control board that a surge can knock out. Turning the power on with an empty tank burns out an element. Our no hot water repair page covers what to check first.
- Gas burner won't light. Dust, spider webs and nesting critters block burner tubes on RV-style units that sat all summer.
- Leaks at the access door. Monsoon rain blowing past a worn door seal can rust the fittings and the floor of the compartment.
- Rusted-through tanks. Once the tank itself leaks, it has to be replaced. No patch lasts. Here's how to spot a tank that's leaking from the body.
My park model water heater has water under it. What should I do first?
Shut the cold water supply to the heater, or the main for the park model if you can't find it. Switch off the breaker and the propane or gas, and set the electric switch to off on RV-style units. Take photos, then call us. Small spaces mean small leaks spread fast into cabinets and floor decking.
Safety: If you smell gas or propane, leave the unit and call 911 and your gas company or propane supplier from outside. Don't flip switches or try to relight.
Working in RV resorts around Apache Junction and Gold Canyon
Apache Junction has many RV resorts, especially along the Apache Trail (see west-side park leak repair) and Idaho Rd; our east-side leak repair page covers the resorts off Idaho, Tomahawk, Royal Palm and Cortez. There are more just west along Main St, covered by our East Mesa leak repair page, and Gold Canyon has more along US 60. Most of them have rules for contractors.
- Tell us your resort and lot number when you call, so we can plan parking and the gate.
- Check in with the office if your resort asks for notice before a contractor visit.
- Ask whether the heater is yours or the resort's. On a rented unit, the owner or resort office usually signs off on a repair.
- Clear the access door or closet of plants, storage bins and hoses.
Many park model owners are seasonal. If you're closing up for the summer or opening back up in the fall, see our snowbird water heater service, or work through our printable snowbird checklist yourself.
Replacing a park model water heater
When the tank is rusted through or repairs no longer make sense, we replace it with a unit that fits the space, the connections and the power or gas you already have. Like-for-like is usually the simplest choice: same size, same fuel, same footprint. You'll get our price for the swap before we start, and the cost question in the FAQs gives area context.
Do I need a permit to replace a park model water heater?
For electric, often not. Inside Apache Junction city limits, City Code § 7-1-6 says replacing an electric water heater with one of equal or lower amperage does not need a plumbing permit in a park model serving one dwelling, as long as the code-required bonding and disconnecting means are already there. The work still has to meet code. Gas replacements, bigger units, fuel switches and relocations are a different story. Outside city limits, including Gold Canyon, Pinal County sets the rules. Rules change, so confirm with the city or county for your address, and ask us about permit requirements. Our guide to water heater permits in Apache Junction has more detail. This isn't legal advice.
Can an RV-style unit be swapped for a home-style tank?
Sometimes, but it's rarely a straight swap. The wall opening, venting, gas supply and wiring are all different. In many park models, a matching RV-style unit is the cleaner fix. We'll walk through both options if you ask.

Park model water heater FAQs
What size water heater is in a park model?
Most hold somewhere between 6 and 20 gallons. RV-style units built into an outside wall are usually 6 to 10 gallons. Small electric tanks inside a closet tend to run 10 to 20. Check the label on the unit, or send us a photo of it when you call.
Can you fix an RV-style gas and electric water heater?
Yes. We work on RV-style units with gas, propane, electric or both. Common fixes include elements, thermostats, igniters, burner cleaning and leaking drain plugs. If the tank itself has failed, we'll match a replacement to the wall opening and connections you already have.
Why does my park model water heater smell like rotten eggs?
Usually because a small tank sat warm and unused between visits, letting bacteria react with the anode rod. Flush it and run the hot water. RV-style units differ: some have an aluminum rod and some aluminum tanks have none, so check your model before buying a replacement rod. Our anode rod replacement page explains the fixes.
Is a park model water heater cheaper to replace than a house tank?
Often, but not always. The units are smaller, but RV-style heaters and tight spaces can add parts and labor. For context, Angi lists an Apache Junction install or replace average of about $1,136, typically $819–$1,320, but that mostly reflects full-size tanks. You'll hear our price once we've seen the unit. See the replacement cost guide for more.
Should I shut off the propane to my park model water heater for the summer?
Yes. Close the propane at the tank or the unit's gas valve, switch the electric side off, and shut the water supply to the heater. An RV-style unit left on for months with nobody around can leak for weeks unseen, and a storm surge can damage its control board. Our snowbird checklist covers the rest of the close-up.
