How to troubleshoot Camper Van Plumbing
RV and camper van plumbing systems can develop leaks. This guide covers fixing leaks in fresh water and waste systems using PEX fittings.
Step-by-Step Fix
- Turn off the water pump and relieve pressure by opening a faucet.
- Locate the leak and determine if it is a fresh water or waste line.
- For fresh water: cut out the damaged PEX section and install a new PEX coupling with crimp rings.
- For waste lines: use ABS or PVC pipe and fittings with solvent cement.
- Secure all connections and let the cement cure before testing.
- Turn the pump back on and check for leaks around the repair.
