Performing RV plumbing repairs in your particular camping unit is a part of regular maintenance. Inspection at the beginning of the season is a must if your sojourns to our great campgrounds are to be a success. No one wants the RV sewer system acting up while they are on vacation, especially their campsite neighbors.
By checking the RV plumbing at least annually, most plumbing problems can be prevented or repaired before they cause trouble. Leaky faucets should be fixed as soon as possible by replacing the rubber seals and valve seats just as you would in your home. It is a good idea to replace them every two years even if they aren't leaking.
Since these RV plumbing parts are usually not subjected to water but a few times a year, they tend to dry out and become hard and brittle. If not changed they may not seal correctly or possibly break. The same goes for the shower and bath fixtures.
RV Water Supply Lines
The water supply lines in a RV can be of different materials, but all have one purpose., to deliver water to the sink, bath, shower, or toilet. Flexibility is one common requirement the different materials possess because of the flexing experienced while the camping unit is being transported to and from the campsite.
Older camper units may use copper tubing, while newer models use flexible plastic materials. The copper tubing may require a flare tool when replacing or repairing a broken water line, while the flex rent dumpsters tubing uses rubber or plastic pressure fittings to insure a good seal. These parts can be found in most Home Depot or Lowe's building supply stores.
RV and camper trailer toilets have different mechanisms than that used at home. Instead of retaining water in them at all times they use a trapdoor type slide and water flush component to dispose of the waste. The water connection to the toilet is no different than used at home.One of the most common problems with the toilet is incomplete closing of the sliding trap door.
The slide fits snugly into a groove when operating correctly. After a period of time, bits of toilet paper may become lodged in the groove preventing the slide from closing tightly. This will allow air to seep from the waste holding tank causing an odor problem. Carefully clean this groove with a parking lot small piece of wire until the slide will seat properly into the groove.
