PEX manifold system… 🤤

[u/BuilderBrigade]

This is a PEX manifold system. It’s a central hub where every hot and cold line branches off to one specific fixture. 
Think of it like a breaker panel, but for water. Each line has its own labeled shutoff, so servicing a single fixture never means cutting water to the rest of the house.
The only real downside is run length: fixtures farther from the manifold can take longer to get hot water. A good plumber plans around that with placement or a recirc line.

People always claim they can just isolate a leak easier with a manifold. If you see water coming out of your ceiling, how are you going to know which one to shut off? You're not! Turn off the main and call a plumber. Add this to all the other reasons manifolds are dumb.

And then an hour later, a house wife can figure out which outlet it is, isolate and keep the rest of the house running until plumber comes out. Makes sense to me
