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 Review: Been using for awhile is good quality and works well. We are off grid and set up with rv pump for water in our house. ## Features - 2 Gallon (8L) Expansion Tank - 4-Year Warranty! - Increases the life of your pump and battery, while reducing sound and providing a more consistent water supply. - Set Accumulator ~3 PSI below water pump cut-in pressure for optimal usage - Connect Accumulator Tank to outlet side of water pump for best results ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B082DKMYLT | | ASIN | B082DKMYLT | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #173,657 in Sporting Goods ( See Top 100 in Sporting Goods ) #376 in Boat Plumbing | | Color | Black | | Customer Reviews | 4.6 4.6 out of 5 stars (122) | | Customer reviews | 4.6 4.6 out of 5 stars (122) | | Date First Available | 9 December 2019 | | Date First Available | 9 December 2019 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 2 Kilograms | | Item model number | SFAT-087-021-01 | | Item model number | SFAT-087-021-01 | | Manufacturer | SEAFLO | | Manufacturer | SEAFLO | | Material | Polypropylene (PP), Stainless Steel | | Part number | SFAT-087-021-01 | | Power source type | Battery Powered | | Product Dimensions | 19.99 x 19.99 x 33.02 cm; 2 kg | | Product Dimensions | 19.99 x 19.99 x 33.02 cm; 2 kg | | Style | Diaphragm | ## Product Details - **Brand:** SEAFLO - **Colour:** Black - **Material:** Polypropylene (PP), Stainless Steel - **Product dimensions:** 20L x 20W x 33H centimeters - **Style:** Diaphragm ## Images ![SEAFLO Pre-Pressurized Accumulator Tank (2 Gallon) - Image 1](https://m.media-amazon.com/images/I/61Uk+5VvHHL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by E***3 on 1 February 2025* I bought this accumulator to try and stop the pulsations of the water pump in my RV.
