Camper Plumbing: Quick-Fix Guide For Your Next Trip

how to fix plumbing in a camper

Plumbing issues in a camper can be a huge mess and a headache to fix. It is important to fix leaks as soon as possible to prevent severe water damage and mould from occurring. The first step is to turn off the water and locate the source of the leak. This may be under the sink, in the storage area near the water pump, or even under the RV. Once the leak is found, clean up the water and observe the leak with the water turned back on to assess its severity. If there is a break in the line, cut out the damaged section and rejoin the two ends with a fitting. If the fitting is the issue, they can be purchased at a hardware store. When replacing the fitting, wrap the threads with Teflon tape to prevent leaking.

How to fix a water supply line

Fixing a water supply line in an RV is not as daunting as it may seem. The water lines in most RVs are made of plastic "PEX" pipe, which is accessible for repair and not buried inside walls. Here is a step-by-step guide to help you fix a water supply line in your camper:

Step 1: Understand Your RV's Plumbing System

Before attempting any repairs, it is crucial to have a basic understanding of how your RV's plumbing system works. Familiarize yourself with the freshwater inlet valve, the water pump, the water tanks (freshwater, gray water, and black water), and the plumbing fixtures like faucets, showerheads, and toilets.

Step 2: Locate the Leak

When you discover a leak, the first step is to locate the source. Check inside cabinets, outside storage spaces, and even under your RV. Removable panels will grant you access to plumbing areas behind the shower faucet and around the water heater.

Step 3: Identify the Type of Water Line

There are two types of water lines commonly found in RVs: copper lines and plastic lines. Copper lines are typically found in older RVs, while plastic lines, specifically PEX tubing, are the material of choice for modern vehicles. Identify which type of water line you have so you can purchase the appropriate repair parts.

Step 4: Gather the Necessary Tools and Fittings

For plastic water lines, a utility knife or a tubing cutter designed for PEX will allow you to make clean cuts. You will also need fittings to rejoin the water line. Compression union fittings are ideal for this purpose, and you may require a wrench or pliers for a secure connection. If you have copper lines, use a tubing cutter to avoid deforming the tube.

Step 5: Cut and Rejoin the Water Line

Once you have located the leak, cut out the damaged section of the water line, ensuring you only remove the necessary length. If possible, leave some slack in the line to allow for easy rejoining. Use the appropriate fittings to reconnect the two ends of the water line.

Step 6: Prevent Future Leaks

To prevent future leaks, it is recommended to use a water pressure regulator whenever you connect to a water hookup. This will protect your water lines from bursting due to high water pressure. Additionally, consider investing in an RV water filter to keep your water lines clean and odor-free.

Remember to take your time, work carefully, and if in doubt, consult a professional. By following these steps, you can confidently fix a water supply line in your camper and ensure a reliable plumbing system for your RV adventures.

How to fix a broken water line

Fixing a broken water line in your camper is a job that can be done by yourself, but it's important to act quickly to prevent water damage. First, turn off the water supply and locate the source of the leak. Clean up any water and assess the severity of the leak. You'll likely find that the water lines in your camper are made of plastic PEX (cross-linked polyethylene) pipe, which is easy to repair.

To fix a broken water line, you'll need to cut out the damaged section of the pipe and rejoin the two ends with a fitting. Here's a step-by-step guide:

  • Cut out the damaged section of the water line: Use a tubing cutter designed for PEX to ensure a clean, straight cut. You can also use a utility knife for plastic water lines, but be careful not to deform the tube. Leave enough slack on each side of the cut to work with.
  • Pick the right fitting: Take the cut-out section to a hardware store to find a compression union fitting that fits. You want a tight fit, but you shouldn't have to force the tubing through.
  • Install the fitting: Slide the tubing through the holes in the fitting as far as they will go. Then, use a wrench to tighten the nut in the middle and secure the connection. Give the tubes a gentle tug to test that they are firmly in place.
  • Test the system: Turn the water supply back on and check for any signs of leaking around the repaired area. Also, check that the faucets and shower are functioning properly.

Some additional tips to keep in mind:

  • If you're dealing with a leaking elbow fitting, simply unscrew the lock nuts and replace it with an identical fitting. Don't forget to wrap the threads with Teflon tape to prevent leaking.
  • Always use a water pressure regulator and an RV water filter to protect your water lines and keep them clean.
  • Sanitize your water lines occasionally to prevent weird smells and keep your water fresh.

With these steps and tips, you'll be able to fix a broken water line in your camper and get back to enjoying your RV adventures.

How to fix a burst water line

Fixing a burst water line in a camper can be a daunting task, but with the right tools and knowledge, it is certainly doable. Here is a step-by-step guide on how to fix a burst water line in your camper:

Locate the Leak

Before you start repairing, you need to find the source of the leak. Turn on the water pump and look for water leaking or spraying out. Check behind the shower faucet, inside cabinets, under the RV, and even under the bed storage areas. Removable panels will give you access to plumbing in certain areas.

Identify the Type of Water Line

Once you've located the leak, identify the type of water line you have. Most modern RVs use plastic (PEX) lines, while older RVs from the 1960s or 1970s may have copper lines. Knowing the type of water line will help you determine the appropriate repair method and materials.

Cut Out the Damaged Section

If the water line has frozen and split, you will usually have enough slack in the line to cut out the damaged section. Use a utility knife or a tubing cutter designed for PEX to make a clean cut, removing only the section with the split. Be sure to cut out only the damaged portion, leaving enough line to rejoin the two ends.

Rejoin the Water Line

To rejoin the two ends of the water line, you will need a compression union fitting and a wrench to tighten it securely. If there is not enough slack in the line, you may need to use two fittings and a new section of tubing to make the repair. Take the damaged piece with you to the hardware store to ensure you get the correct fitting.

Turn on the Water Pump

After you have rejoined the water line, turn on the water pump to test your repair. This will give you peace of mind that the leak has been fixed and everything is functioning correctly.

Prevent Future Issues

To prevent future issues, it is important to properly maintain your RV's water lines. Always use a water pressure regulator when connecting to a water hookup to protect against high water pressure that can cause lines to burst. Invest in an RV water filter to keep your water lines clean and free of odd smells. Finally, remember to sanitize your water lines regularly to ensure they remain in good condition.
