Review: product assembled and works well - After reading some of the negative reviews, I was somewhat concerned with ordering these manifolds. I ordered a 2, 3 and an 8 loop manifold for a 3 zone system. When the manifolds arrived, they looked like they were manufactured in the same plant as a previous manifold I bought that I paid significantly more for. Everything assembled quickly and I had no leaks. It looks to me like they have updated the design to work with standard tapered pipe fittings. I had no issue with the 1" threads bottoming out before they got tight. They look like standard tapered pipe threads, not British or fuel threads some reviewers were having issues with earlier. I have been very happy with these manifolds any would buy them again. I can't speak to the longevity but hopefully they will last .
Review: High quality - Excellent manifold. High quality and much cheaper than other brands. Comes with all the compression fittings for 1/2” Pex.

Excellent manifold. High quality and much cheaper than other brands. Comes with all the compression fittings for 1/2” Pex.

### ⭐⭐⭐⭐⭐ Good quality, works well, includes everything needed
*by W***A on November 25, 2021*

Everything appears to be good quality so far. Been using it for a couple months now. Only issue I had is one of the ports isn't being used and while it was turned off so water wouldn't come out, it is now dripping. This could be due to lower temps recently and my wood boiler not running during that time. Easy enough to use a piece of PEX tubing and cap it off. No instructions included, but it's pretty simple and plenty of resources on Google.
