Review: Amazingly Affordable PVC Unions - Works perfectly! Got them to make a saltwater sump and they fit perfectly. Definitely much cheaper than other places but still excellent quality. I have had zero problems with anything leaking. Super easy to install, just make sure to pvc glue them!
Review: Perfect! No leaks! And they look good too. A good price and product. - Nice unions! Don't leak. Comes with additional gaskets. Easy to install. Easy to get apart if needed. A nice size too. Seems to be well made. I am happy with it for the price you can't beat it. Just make sure you have the screw part of it on your pipe before you glue it or you can't get it on there. Glad I bought these.

### ⭐⭐⭐⭐⭐ work
*by C***T on October 28, 2025*

Worked perfectly for replumbing my pool to have a faster drain-down option. Most importantly, having this also allowed me to keep my original plumbing intact with no cutting pipes in case I wanted to just switch back to the original for some reason. All the new connections (to the filter, pump, and this union on the discharge pipe) were screw on/off. Perfect fit on 2" schedule 40 pipe. I have no idea why some are saying it's too big unless they're some kind of non-standard pipe. I also liked how heavy duty these are -- they match the rest of the Jandy pool valves/connections so they look like they're supposed to be there .
