Easy purchase

Accumulator pressure tank for fresh water system on our 60 foot motor yacht. Product works well. It did have a large dent on arrival but is in a hidden location and does not affect its function.

Quick delivery, exactly as described and works perfectly

I've had a problem with water heater induced pressure build-up for years, finally decided that I needed to fix it and ordered this unit. Shipping was very fast, installation was easy and it works perfectly!

Easy, simple, reliable

The tank is simple and easy to install. Its self-standing was a welcome feature. I only wished that the inlet was located on the opposite side of the labeling, so that I could install the tank with the piping hidden, but still have view of the label for future maintenance.

Good Size - Easy to Install

I have a solar water heating system tied to a hydronic radiant floor. I put this tank on the potable water side of my heat storage. Compact size to reduce the amount of floor space.

Yes, you can use this unit. You can also use the 141N43 if you are just using one tank.
