I have a remote shop that we added a bathroom in and decided the 12v RV instant water heater made more sense than the traditional electric ones. After it was installed (on our county water supply) I would find a puddle of water from time to time. After some research I realized the expansion was the issue and added this tank. Problem solved. I realize instant water heaters aren’t supposed to need a tank but my application did and it was a cheap solution. Loved the built in mounting points. I will add pictures at a later update. ### ⭐⭐⭐⭐⭐ The tank has a factory installed mounting bracket *by L***R on Reviewed in the United States on 12 June 2023* The installed mounting bracket makes mounting easy. I used the tank in a recreational vehicle mostly to reduce water pump cycling, but also to eliminate water heater pressure valve release. ### ⭐⭐⭐⭐⭐ Glad I bought this! *by M***R on Reviewed in the United States on 8 March 2023* This was a win... easy to install and seems very well made. It works GREAT to minimize pump cycling on my sailboat, it actually feels like I'm moving up in the world when I wash the dishes now because I don't have to listen to the pump going on and off. :) I just installed it so no comment on durability but so far I'm very happy with it and feel that its a great value when compared to the plastic versions with smaller capacity. ## Frequently Bought Together - 2 Gallon Accumulator Expansion Tank With Wall Mount Bracket 1/2" Female NPT - WiseWater 110V Circulation Pump, 130W 13 GPM Hot Water Recirculating Pump, 3 Speed Switchable Circulator Pump with 1'' FNPT Flanges for Boiler, Solar Heater and Hydronic Radiant Heating, Red --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/545487851-2-gallon-accumulator-expansion-tank-with-wall-mount-bracket-1](https://www.desertcart.vu/products/545487851-2-gallon-accumulator-expansion-tank-with-wall-mount-bracket-1) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
