How to Repair Water Lines in an RV

How to Repair Water Lines in an RV
RV water lines are often not as sturdy as their household equivalents, and they have much more potential for wear and tear due to freezing. This means the owner of an RV must be handier with basic plumbing than the owner of a house, lest they wind up paying for expensive repairs on leaky water lines all the time.


Difficulty: Easy

Things You’ll Need:
  • Pocket knife
  • PVC saw
  • Spare plastic tubing and/or PVC pipe
  • Tubing and/or PVC pipe fittings
  • PVC adhesive
Step 1
Turn off the RV's water pump and open the faucets around the leak to drain the water line.
Step 2
Cut out the damaged section using a pocket knife for plastic tubing or a PVC saw for PVC piping.
Step 3
Cut a new section of tubing or piping the same length as the damaged section to serve as a replacement. In the case of a plastic tube with plenty of slack, this might not be necessary.
Step 4
Patch up the water line. For a plastic tubing with plenty of slack, you can do this with one fitting. Fittings for plastic tubing are often of the push-in or screw-in variety, so simply put the two ends of the severed line into a single fitting. For plastic tubing with no slack, use two fittings attached to the ends of the severed water line and a new section of tubing inserted between them. For PVC piping, use the two fittings and a new section of tubing between them again, fastening it all together with PVC adhesive.
Step 5
Allow the PVC adhesive to dry overnight, if it was used.
Step 6
Switch the water pump back on, open faucets around the repaired area and check for continued leaks. There might have been a flaw in how your did the fittings or perhaps another leak you did not detect.

Tips & Warnings

Take the damaged piping or tubing with you to the plumbing store when you go to buy replacement parts. This is a classic do-it-yourself tip for avoiding purchasing the wrong parts and only discovering it when you are trying to install them.
