With the new and modern RVs coming out today, a RV water pump is most likely already a standard inclusion in the package. RVs nowadays are so complete and comprehensive, that they can rival most real homes. The water system for example, is already integrated into the trailer and it has its own water pump working the needs of the household. With regular use though, this pump can wear out and eventually fail. Here is some help for replacing the old, worn out RV water pump.

Step 1: Drain the Water Tank

Drain all the water from the water tank of your RV and make sure that everything is flushed out and no residue remains. Do this by connecting a water hose at the base of the tank to siphon out all of the water. You can save the water if you wish, by directing the hose to a drum or large pails. Now, disconnect the link from the tank to the RV water pump. Expect some water to still spill out.

Step 2: Remove Old Water Pump

Remove or disconnect the battery of the RV. Using the screwdriver, remove the wires connected to the old RV water pump. These wires should be colored black and red. There should be hoses connected to the pump and you need to disconnect them at this point. Remove the bolts and screws holding the pump in place. After this, carefully remove the pump from its resting place.

Step 3: Install the New Pump

Get the new RV water pump and position it where the old pump was. Secure it in place using the screwdriver and bolt it down tightly. Get your Teflon tape and wrap the threads of the pipes with it. Connect the inlet hose then the outlet hose and secure them both with the clamps that support them.

Step 4: Reconnect Water and Electrical System

Reconnect the link of the water tank to the pump and fasten it well. Now re-connect the electrical wiring that you removed earlier. Finally, reconnect the RVs battery, so your new RV water pump has a live power source.

Step 5: System Test

Test the system by starting your RV and seeing if the pump goes on standby. You should hear a sound coming from your pump, signifying that it is turned on and that it is working. The type of sound may vary depending on the kind of pump you have installed. If you don’t hear anything, check all electrical connections and see if they are connected properly. Make sure also that the battery is working and that it is connected.

Step 6: Pump Test

After you have determined that the pump is actually running, check all lines and connections for leaks and holes. Fill the tank about ¼ the way with water. Turn on the pump and let it do its job. Go to a faucet and turn it on. It might take a few moments for the water to come out, because the RV water pump is still filling the lines with water before it reaches the faucet.
