RV Water Line Maintenance and Repair – Read This First


Our Camping Adventures

Water lines are a vital part of any RV. Without them, campers wouldn’t have running water for showers or dishwashing. Therefore, caring for your water system and repairing your RV water lines and fittings when necessary is an important part of RV maintenance.

RV Water Line Maintenance

Wondering what you should be doing to take good care of your RV water lines? Remember these things:

Purchase an RV Water Pressure Regulator

Make sure you are using a water pressure regulator every time you connect to a water hookup. This will protect your RV waterline tubing from bursting due to high water pressure. 

Invest in an RV Water Filter

An RV water filter will help clean the water before it enters your rig’s water lines. This will keep the lines clean and free of weird smells.

Sanitize RV Water Lines

In addition to using a filter to keep thing clean, it’s a good idea to sanitize your lines from time to time. Our instructions on how to do this can be found here

How to Blow Out RV Water Lines

Before freezing weather hits, it’s important to winterize your water system. Some people use antifreeze in their water lines, while others feel it’s ideal to blow out RV water lines. We find the latter is a bit cheaper, easier, and cleaner.

Not sure how to blow out your RV water lines? Start by emptying all water lines and water tanks. Attach a blow out plug to your water intake valve. Have a helper go inside the RV and ensure all taps are closed except the one closest to the intake valve, which should be fully open. Using an air compressor and a tire pump tip, blow air through the blowout plug until you hear the tap squeal. At that point, stop the compressor, close the first tap, and repeat the process at the next closest tap. Do this with every tap (including the toilet), and you’ll have a nice dry system.

RV Water Line Repair

Unfortunately, no matter how careful you are, things will break over time. Luckily, RV plumbing systems are relatively easy to work on as long as you can get your hands on the right RV water line repair parts.

RV Water Line Fittings

Usually, a leak can be fixed quickly and easily using RV water line connectors. Simply cut out the damaged part of the tubing and reconnect the two parts using RV water line fittings. You can choose between RV plastic water line fittings or metal fittings. Either way, you should only need simple tools such as a wrench or pliers to do the repair. 

Replacing RV Water Lines

Occasionally, a leaky line won’t have enough slack to be repaired as described above. In these cases, you will need to purchase some extra RV water line repair parts: an extra bit of tubing and a second connector. Use the two connectors to put the extra tubing between the two original pieces of water line and you’ll be good to go.
