## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Solved my problem
  

*by W***5 on Reviewed in the United States on 15 May 2023*

I installed the tank to eliminate a problem with my RV instant water heater. 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.
