SEAFLO 2 Gallon Pre-Pressurized Accumulator Expansion Tank – Reduces Pump Cycling, Smooth Water Flow, 87 PSI, 3/4" MNPT, Compact Design for RV, Marine, Boat & Off-Grid Systems – 4-Year Warranty

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

Great! Marine water pump runs less/ does not lug for small pressure drops. Easy to adjust pressure, there is no problem with the 3/4npt nipple, not sure what happened with that guy.AndThe water doesn’t look like a rain puddle underneath some cast member of Jersey shore anymore. (The nipple is stainless and doesn’t rust)It’s great

We're using this with our Seaflo water pump in our rv. Together they make us forget that we're not in a house with city water pressure. Specifically, this tank acts as a baffle to eliminate the shake, rattle and delayed roll most rvs have when running the water pumps. The functionality gives you peace of mind and places you back in the mindset of a home with typical city water pressure immediately at the tap every time. It also improves the longevity of your water pump performance and longevity. It a quick, easily installation with a new install or a retro fit that's easily a value for the monty.

Used as a pressure equalizer.

Basically a great item but only ships as a tank. Needs a holder/mount or should reference where to get one.

Just spent a week trying to get this to work. As the other reviews state, the threads are all wrong on this. I even tried ordering a special adapter that was recommended, but that failed as well.

Bought for a garden irrigation pump.works great

At first I connected it to the supply side of my rain water catchment system. When it didn’t do anything I realized I needed it on the pressure side. Since it is small it doesn’t prevent the pump from running much but it does make a difference and I’m glad I have it. Other than reducing pump usage it also helps cushion water hammer from the pump cycling on and off. Quality items from Seaflo. I also use their series 33 pump.
