How does a water pump work?

A water pump is designed to move liquid from one chamber to another. It works by sucking the liquid into one side of the chamber and discharging it out from the other side of the chamber. The liquid passes through an impeller that turns within an enclosed chamber. The impeller is usually driven by a pulley or belt system which causes it to rotate rapidly. This rotating impeller creates suction that draws liquid into the chamber and forces it out through an outlet pipe on the opposite side of the chamber.

What is the average cost for a water pump?

The cost will vary widely depending on where you live, the type and size of your RV and what type of water pump you have in your vehicle. The average cost for a new water pump will be around $250. This average cost is taking into consideration that not all water pumps are built the same.

There are three main signs your water pump needs replacing:

  1. Low water pressure
  2. Too much of a high water pressure
  3. Noisy, loud operation

The water pump is the heart of your RVs plumbing and water system. If the pump goes out, you will have no running water. That means you won't be able to flush the toilet, take a shower or wash dishes.

However, just because it stops working doesn't mean that you need to replace it. Sometimes it can be repaired and other times you will need to replace it. Here are a few things that you can do to find out if you need to replace your RV water pump or not.

How to test your pump

  • Test the 12-volt power supply:
  • Most problems with your water pump are caused by loss of power from a bad fuse or wire connection. So, when your pump stops working, test the 12-volt power supply first before throwing out the old one for a new one. If there is power going to the pump but it's still not turning on then move on to step two.

  • Remove the pump and inspect
  • Next, remove the water pump from its position under the sink and inspect it very carefully for any signs of damage or wear and tear.

    It's possible that the impeller blades inside of the pump have been damaged or worn down due to rust or corrosion.

  • Test your water pump pressure switch
  • The pressure switch starts and stops the water pump when the faucets open or close. This can be tested with a simple multimeter. Make sure that all of your faucets have been closed and then unscrew the pressure switch from the top of the RV water pump.

    Once you have removed the pressure switch, connect one lead from your multimeter to each terminal on the switch. The terminals are usually marked with L and N for low and high pressure; however, some models may not be labeled in this way.

    Turn on your multimeter and look for a reading between 30 PSI (pounds per square inch) and 45 PSI (pounds per square inch).

A water pump is a vital part of your RV's plumbing system. It draws water from the freshwater tank, to be used in the sink, toilet, shower, or elsewhere. It can also draw water from an outside source, such as a hose connection, if you're on city water.

When you turn on the faucet in your RV, a valve known as the demand pump opens. This allows water to flow from the freshwater tank, through the pump and out through the faucet. When you stop using it, the demand pump will close until pressure builds up again.
