## Customer Reviews

### ⭐⭐⭐⭐⭐ Works perfectly on my tankless system.
*by J***T on June 24, 2026*

Just as described. Crazy to think this replaces my old expansion tank. Can't beat the price.

### ⭐⭐⭐⭐⭐ Small tank for a 2 gallon water storage tank
*by H***N on July 21, 2025*

I put this on the input to the pressure regulator to absorb the water pressure surge when the pump comes on. It keeps the pressure switch from hammering on and off.

### ⭐⭐⭐⭐⭐ Great fix for significant water hammer
*by J***E on December 14, 2025*

We replaced or clothes washer with an HE version. The new washer ware control valves are quick close and created severe water hammering. I tried the AA size anti water hammer device. Still slammed the pipes. I bought this larger unit that is designed for a water tank up to 2 gallons. It is small and was able to squeeze in to my arrangement. I had to install a wye to replace the multi tap AA device. But now all is silent. This device has an air chuck to adjust the pressure. A QR code directs you to instructions that simply say “pressurize to 3 to 5 psi above normal pressure”. It would be nice to say that on the permanent tag on the unit or at less have the QR code on the device, not the box.
