Review: I bought this accumulator to try and stop the pulsations of the water pump in my RV. They have smaller versions of this that are about a quart in size. I chose to go with the 2 gallon one. it is obviously larger and takes a little more room in a cabinet but so worth it. Installation was not to difficult, except for working in a cabinet. You will need to buy some pipe fittings to install it also. it worked so good, no more pulsations in the water, just like home. They pump does run longer when the pressure in the tank drops to the cut in point however it does not run as often and turn off and on rapidly with lower water flows. I highly recommend one of these for your RV
