How is mobile home plumbing different?
Mobile and manufactured home plumbing is different because the pipes run under the floor, inside a crawl space behind the skirting, instead of in walls or under a slab. Many older homes have gray polybutylene pipe, smaller drain lines and a water heater that must be rated for manufactured homes. A plumber who knows these homes can fix them fast.
Key things to know about your home's plumbing:
- Pipes run under the floor, reached by removing a skirting panel
- Gray polybutylene pipe is common in older homes and can fail
- Water heaters must be approved for manufactured homes
- Drains are often smaller, so they clog more easily
- Park rules can affect who fixes what
Manufactured homes built since 1976 follow the federal HUD Code.

How do you know there is a leak under your mobile home?
Signs of a leak under a mobile home are a soft or bouncy floor, a musty smell, water dripping from under the skirting, low water pressure and a water bill that keeps climbing. Leaks under the floor can go unseen for weeks, so look under a skirting panel with a flashlight if anything seems off.
Other signs your Rancho Carlsbad home needs a plumber:
- A soft spot in the floor, often near the bathroom or kitchen
- Low water pressure at more than one faucet
- A water heater that will not heat or is leaking
- A toilet that rocks, often a sign of a weak floor or a failed seal
- Slow or clogged drains in a smaller drain line
- A high water bill with no change in use
What is polybutylene pipe, and why does it fail?
Polybutylene is a gray plastic pipe that was widely used in homes, including many manufactured homes, from the late 1970s into the 1990s. Over time, chlorine and other disinfectants in tap water can make it brittle from the inside, and the fittings can crack. It often fails without warning, which is why many owners replace it.
Should I replace polybutylene pipes now?
If your home still has polybutylene, replacing it before it fails is the safer choice. A leak under the floor can damage the subfloor and lead to mold.
Why do mobile home drains clog more often?
Many manufactured homes have smaller drain lines than site-built homes, often made of ABS plastic. Grease, wipes and food scraps clog them faster. See drain cleaning.
Why is my mobile home water pressure low?
Low pressure can come from a polybutylene leak, a failing pressure regulator, a clogged shutoff valve or scale in older lines.
Who is responsible for water lines in a mobile home park?
In most California mobile home parks, the park is responsible for the water and sewer lines up to the connection at each home site, and the homeowner is responsible for the plumbing from that connection into the home. California's Mobilehome Residency Law and your rental agreement spell out the details. Check with park management first.
- Call us. We answer 24/7 and help you stop the water.
- Find the source. We check under the home to locate the leak.
- Show who owns it. We note whether the problem is in your home's plumbing or at the park's connection.
- Park approval. We help you check whether the park needs to approve the work.
- The repair. Done to code, with a permit when needed.
- Test and close up. We test the line and put the skirting back.
How do I get park approval for plumbing work?
Ask park management what their rules say for plumbing work. Some parks want notice before a contractor works on site. We can talk with management for you.
Can you repipe a mobile home?
Yes. A mobile home repipe replaces the old polybutylene with new PEX or CPVC pipe. Because the pipes run under the floor, a repipe is often faster and less messy than in a site-built home. Most of the work happens in the crawl space, with only small openings inside for fixtures.
- Polybutylene pipe replacement with PEX or CPVC (see repiping)
- Mobile-home-rated water heaters, gas and electric (see water heater repair)
- Leak repair under the floor with the right fittings
- Drain cleaning for smaller mobile home drains
- Pressure regulators and new shutoff valves
Can I use a regular water heater in a mobile home?
No. A manufactured home needs a water heater that is approved for manufactured homes. These have the right venting and safety features for the space. We install the correct type.
Should you use PEX or CPVC in a mobile home?
Both are approved for many manufactured homes. PEX is flexible, handles small ground movement well and needs fewer fittings, which means fewer places to leak. CPVC is rigid and works well too. We recommend the best fit for your home and what your local rules allow.
- Repair vs repipe polybutylene: a single repair is a short-term fix; a repipe ends the worry
- Fewer leaks with fewer fittings in a PEX system
- Better water pressure with new pipe
- A dry, solid floor with no hidden leaks
- You can usually stay home during a mobile home repipe
How do you find a good mobile home plumber?

Who issues permits for mobile home plumbing in California?
In California, permits for plumbing work in many mobile home parks come from the state Department of Housing and Community Development (HCD). In some places, the local city or county handles it instead. Small repairs may not need a permit at all. We check what applies to your home and your park before starting.
- HCD: oversees most mobile home parks in California
- Mobilehome Residency Law: sets rules between park owners and residents
- HUD Code: the federal standard for manufactured homes built since 1976
- City of Carlsbad: may be involved for some work and park utilities
- Water: check your bill; some parks have their own meters for each home
- License you can check: search our business name on the CSLB license lookup
How long does a mobile home repipe take?
Many mobile home repipes are done in one to two days, because most of the pipe runs in the crawl space and is easy to reach. Water is usually back on at the end of each day. Here is how a typical Rancho Carlsbad polybutylene repipe goes.
Typical job (an example of how these calls go, not a specific customer):
- The problem: a resident notices a soft spot in the hallway floor and a musty smell, and the water bill has gone up.
- The check: the tech removes a skirting panel and finds water dripping from a cracked polybutylene fitting under the bathroom.
- The cause: the original gray polybutylene pipe has turned brittle, and more fittings show signs of wear.
- The fix: after the resident checks with park management, the whole home is repiped with PEX in the crawl space, with new shutoff valves.
- The test: every line is pressure tested and each fixture is checked for leaks.
- The result: no more leaks, better pressure and the skirting put back neatly.
Do I need a permit for mobile home plumbing in California?
Some work does, like a repipe or a new water heater, and some small repairs do not. In many parks, permits come from the state HCD. We check before we start.
When should I replace my mobile home water heater?
Replace it if it is leaking, rusty or not heating well and the problem is the tank. Make sure the new one is rated for manufactured homes.
How do I find a leak under my mobile home?
Turn off all water, then check whether the meter is still moving. Look under a skirting panel with a flashlight for drips or wet ground, or call us to find it.
Do regular plumbers work on mobile homes?
Some do, and some do not. Ask if they have worked on manufactured homes before. We do.
Is it safe to stay in my home with a leaking water heater?
Turn off the water and the power or gas to the heater, and call a plumber. A small leak is usually not dangerous, but a gas smell is. If you smell gas, leave and call the gas company.
Who pays for plumbing in a mobile home park?
Usually, the park handles lines up to your home's connection, and you handle the plumbing in your home. Your rental agreement has the details.
Can I stay home during a repipe?
Yes, in most cases. Most of the work happens under the home, and water is usually back on each night.
What is the HUD Code?
It is the federal building standard for manufactured homes built since 1976.
