## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy install
*by A***R on May 20, 2025*

Perfect fit for the water heater, the damper and the supply. No leaks!

### ⭐⭐⭐⭐⭐ A no-brainer item when installing a smaller hot water expansion tank.
*by C***E on March 25, 2025*

If you are using installing the smaller hot water expansion tank, (and have a little space on top of your hot water tank) then this is a no-brainer for an easy install. Install this, using a 3/4" dielectric nipple on the female end on top your hot water tank. Cold water input goes to the horizontal 3/4" male threads. (For an easy cutoff - use the SharkBite Max Stainless Steel Corrugated Flexible Water Heater Connector that offers a very nice ball valve available here on Amazon.) Lastly, install your tank on top. Looks professional.

### ⭐ Leaks
*by S***S on May 23, 2025*

This products is well made and of good quality. However, it leaked. I did follow the instructions instructions (the box has a QR code tag you scan with your phone to download the manual), and I tried multiple times and it didn't matter how much I tightened it. I decided not to use it and instead I used just a regular bronze tee coupling. I didn't need the 360 degree swiveling after all,
