If you're planning a trip in your RV, you'll want to fix any damaged water lines before taking off. Plumbing repairs can be expensive if you pay have to pay a plumber. There are things you can do to detect leaks and possibly repair them yourself.

Difficulty: Easy

Instructions

Step 1

Put approximately ½ inch of dish detergent in a squirt trigger bottle and then add water until it's full.
Step 2

Pressurize the water line by using a compressor.
Step 3

Spray soapy water on areas where you suspect leaks. Bubbles will form if a leak is present.
Step 4

Check the fitting areas, as freeze breaks often occur at these areas. If you find a leak at one of the fittings, take it off and take it with you to the hardware or RV store to make sure you buy the right size. Replace the old fitting with the new one.
Step 5

Repair a water tank by welding any breaks with a benzomatic torch. All you need to do is heat a screwdriver with a flat tip with the torch and then weld the break with the hot tip.
Step 6

Replace a leaky shower head or hose. You can find these at any department store. Normally, you can reuse the old fittings to connect the new one.
Step 7

Apply a car repair, like Bondo, to cracks on water pumps. Simply fill in the cracks with the putty, smooth out the surface and brush a coat of epoxy to the outside of the water pump.
