## Customer Reviews

### ⭐⭐⭐⭐⭐ Great brand and good reliability
*by S***R on January 30, 2025*

These are really good PVC unions. I needed to match some unions I purchased a couple of years ago at a hardware store. The store no longer carries that brand and the threads on their new brand does not match. I wanted to replace only part of the union and not both half's to avoid redoing all the plumbing connections, glad I found these on Amazon.

### ⭐⭐⭐⭐⭐ Works perfectly (for less than the Big Box store price)
*by D***) on October 18, 2024*

It arrived on time and was in perfect shape in the box. It was used to upgrade a replacement of a segment of PVC for our well pump that was cracked by a 4" tree that had grown directly next to the pipe over the last 10+ years. That whipping tree was repeatedly pushing against the PVC pipe during the winds of hurricane Milton. Before tightening up the coupling I added a bit of teflon grease to the O-ring (Magic Lube brand that I always have on hand for pool-related O-rings) just for that little bit of extra guarantee it would seal perfectly and stay flexible in the Florida sun. I let the PVC cement on everything cure for 2 hours. I only hand-tightened the coupler and upon powering up the pump not a single drop of water leaked out. PERFECT! (Okay, so I got a little primer on the pipes and looking at the picture can't believe I actually was reluctant to cut down the tree... HA!)

### ⭐⭐⭐⭐⭐ Fast and easy problem solver
*by V***E on March 12, 2025*

Easy to install. I placed it in a PVC line from my well. Watertight at 60 psi.
