2 Gallon Pre-Pressurized Accumulator Expansion Tank – Reduces Pump Cycling, Smooth Water Flow, 87 PSI, 3/4" MNPT, Compact Design for RV, Marine, Boat & Off-Grid Systems – 4-Year Warranty

Worked as intended, I replaced my existing expansion tank with this. Made sure to match the water pressure, and everything else was smooth. Size, quality, and noise level did not differ from my old tank, and it was a great price!

Great product. Super happy. The thread is 3/4" MNPT as advertised. Many reviews mention troubles with pipe thread, but a standard 3/4" FNPT to PEX fitting from a local big box worked just fine for me. I've used the much smaller model from their competitor in much more space-restricted camper build. That helped with pump cycling, but this tank changes the game. Flush the toilet and wash your hands - the pump doesn't even kick on. It's only during really prolonged use that the pump is needed. Not to mention the added consistency in pressure. We don't have much use for both sinks and the shower at the same time - but we could if we wanted to now.

My sprinkler system would hammer the water pipes whenever it shut off. I put this in the supply line and now I don’t hear it at all. The small anti hammer devices I tried first made no difference at all. This works great for me.

Easy to install. Match air pressure in tank to water pressure

Very good

Installed easily!

Meets form, fit and function. Hope for Longevity .

Exactly what I ordered

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.

Great quality item, been in use for 6 months now trouble free. Easily fitted especially with a long 15mm flexii hose .Recommend.

Great solid unit like the one I have for my lake water system. Only complaint I have is that I had to build a special unit to be able to mount to the wall.

Works great and was great quality

I purchased a SEAFLO 33-Series pump and the tank. The pump came first. Alone, the pump started and stopped continuously and the flow was jerky. Once the tank was in the system, everything smoothed out and it runs perfectly!!!! There is so much more to this story, but you can assume I think this was a perfect purchase!
