Great Replacement For The AAA Pump
By Trey H.
Oregon
Purchased 05/28/2024 |
Review Posted 07/12/2024
Great replacement, highly recommend it for anyone still on the 4gpm. Able to build a relief valve, more consistent pressure, tougher, and will last me a while. Can't wait to upgrade to 8gpm but this one is holding together great!

My CAT pump went out and I replaced it with this one. Surprisingly it has quite a bit more pressure.
