Are RV Pumps Really That Noisy?

One of the biggest complaints that RV owners have is how noisy RV water pumps are. When it comes to noisy RV water pumps you can experience banging pipes, floor vibrations, water hammer, or even all three, which is more than enough to keep you awake all night. One of the leading causes to noisy RV water pumps is that the manufacturers used a cheap water pump so that they could keep costs down. If a noisy pump is keeping you awake at night, the good news is you can make your water pump quiet by following a few simple steps.

Easy Steps To Reduce RV Water Pumps Noise

  • Step One – You are going to need to find your water pump before you can start making any changes to it. The most common places that RV water pumps are located are under the dinette or in a cabinet by the sink. If you can’t locate it you will need to turn on one of your faucets to follow the noise. Once you have found the pump make sure that it is turned off so you can begin working on it safely.
  • Step Two – Most RV water pumps are held in place by 4 screws. Now place a rubber computer mouse pad underneath your water pump and reattach the screws. This helps to reduce the vibrations put out by the water pump.
  • Step Three – You will need to turn back on the water pump so that you can find the pipes that are rattling every time the pump is working. This part is better done with a friend because they can turn the faucets on and off while you locate the rattling noise. In most cases, you will find the noise coming from a cabinet wall where the cold water runs through the wall.
  • Step Four – Using 1/2 inch foam pipe insulation you will want to wrap each pipe that is making noise. Even though the insulation should fit snuggly over the pipe you might want to secure it at each end with some duct tape.
  • Step Five – Many RV water pumps also fall victim to rapid cycling, which means they turn on and off within 2 seconds when you are using a low flow of water. Before addressing this issue you will need to check to see if your pump is a victim of rapid cycling. To do this, turn a faucet on very low and check the pump. The pump should cycle, but the off time should be more than 2 seconds. If it is less than 2 seconds you want to increase the setting. Do not increase the setting by more than 1 clockwise turn.

Replacement Of RV Water Pumps With Variable Speed Pumps As An Option

If the above steps do not help quiet down those noisy RV water pumps, your other option is to replace the current one with a variable speed pump. This option is going to be a bit more expensive, but the amount of noise that it is able to reduce can make it worth it in the end. Installing an accumulator can also help reduce noise, and also extend the life of your pump. If you are looking for a reliable RV water pump, you may want to consider the popular Shurflo water pump.
