    Rated 5 out of 5 by from Works Good Needs More Fittngs I can't fault the product it does what I wanted, removing the surging and giving a little reserve water without turning on the pump. Can't say it made the pump less noisy, but I didn't expect it to. Would have been nice to have include more fittings. I needed to go from the 1/2" pipe to 3/8" barbed fittings and went to 4 places before finding what I could make work and it was still with an extra adapter. Leaks were a problem with the plastic fittings till a neighbor (retired chemist) told me to seal all the threads with silicon (RTV) sealer before assembling. I use automotive gasket silicon. I let it set over night and it now works with zero leaks. Jim...

    Rated 5 out of 5 by from Works Well On Day One Works well, all the pulsating in the water is gone. According to the directions a 45 PSI pump, has a flow of 30 PSI, so I confirmed the pre charge is at 30 PSI (I am using a SHURflo 45 PSI/3.1 BAR pump). I supplied two screws into the floor, and a new 8 dollar plumbing extension to finish the job. The item came with one adapter to hook up the tank to the pump. If your rig is like mine the manufacture didn't waste any material for future upgrades, so that is why I had to buy an extension to bring the water back to where the pump was running into originally. Item work as described. That is why I give it five stars.

    Rated 5 out of 5 by from Finally quiet I converted to the accumulator tank and a variable flow pump. Installation was easy and straight foreward. Only problem was a damaged fitting on the pump due to very poor packing by Camping World, but I robbed one off my old pump to get going. Now there is no pumping noise outside the RV if the compartment door is closed, or in the kitchen area, and it is VERY quiet in the bathroom/bedroom area. The air pressure is easy to fine tune with any air source and a tire guage. Compared to the former "flush toilet in middle of night and wake everybody up", this is a dream.

    Rated 5 out of 5 by from Exactly as promised... This little gem is a real dandy! I have a 23' travel trailer and three kids. My pump was working overtime, so I ordered this tank online....it arrived in the afternoon after we left Cincinnati for Colorado. So, I was a little disappointed......until I remembered that there was a Camping World in Denver. So, we stopped, I purchased this little beauty and installed it in less than 15 minutes, with the included fittings. It has eliminated the rapid cycling of our pump, and has really made the flow like home. We dry-camped for two weeks, and this item made all the difference. If you get a chance, visit a Camping World store and get one! Camping World is the best! One Warning: The flow is so like home, that you use more water than previously. Watch out!

    Rated 4 out of 5 by from Easy Install in tight spaces Installed with no problems. The new male fittings allow for a direct hookup to the outlet of an existing standard pump, which makes for a quick install. All parts included, no extra fittings or hoses are needed, except for custom installations or limited space on the outlet side of pump. Still need to fill the water tank to see how it smoothes out the flow. Says in directions to make sure pressure of accumulator is equalized to activation of water pressure switch for best results, and will do that this weekend.

    Rated 5 out of 5 by from Does Everything as Advertised My pump moving and tank installation took a little time because of my motorhome's setup. The tank actually came with everything it needed for installation. Pump really runs a lot less, under 60% for full flow. Hand washing at low flow is completed without any pump sometimes. If you happen to own a large RV and have the room, the larger tank would probably be better. Just remember when doing plumbing work to open a fauchet to release the pressure since the tank holds enough water to make a nice sized mess.

    Rated 5 out of 5 by from Shurflo Accumulator Tank I had to change my pump in my pop up camper, when I did it hammered badly. The Parts dept at Camping World helped me with this problem. Using the Surflo Accumulator tank (2290) ended all my problems. The tank was easy to install, the small size made it fit easily in my pop up camper. the threaded ends hooked right up to my fittings. I also added to my new pump (2088-422-444) a Surflo in line strainer (255-313) before the pump. ended all my water problems. Thank you Camping world Churchville NY.

    Rated 5 out of 5 by from Great improvement The existing pump in my travel trailer was noisy, cycled constantly and had unenven pressure. I installed the Shurflo Accumulator Tank, along with the Pump Silencing Kit from Camping World. WOW, what a impressive improvement. 45 minutes start to finish and it took no additional parts to install. The noise is a mere fraction of the original installation and it has home-like consistent pressure. The cost is far less than the new variable speed pumps with the same results.

    Can I replace a 12 volt 4 amp shurflow pump with this one?

    The camper is a 1990 sunline pull behind
    Asked by: Anonymous
    No, Item# 2290 is an accumulator tank for a water pump, not an actual pump. Water pumps are universal, you will need to compare fittings and specs of a replacement unit to what is currently installed to make an informed purchase. <p>If you are looking for a 12v 4amp Shurflow water pump, then you may want to look at < a href=https://www.campingworld.com/flojet-triplex-automatic-water-system-pump-29-gpm-11-lpm>item# 28997</a>.
