Where should a PEX manifold be located?
Plumbing manifolds are mounted in a convenient, accessible location, such as a basement wall or a service closet, to allow access for shutting off individual fixtures. If the manifold is plastic, it needs a minimum clearance of 36 inches (vertical) and 18 inches (horizontal) from a water heater.
Does PEX need to be insulated?
PEX is treated the same as copper, iron, PVC or CPVC for the same end use. PEX tubing does not provide any significant thermal insulation properties and would not meet code requirements without additional insulation.
Does frozen PEX crack?
PEX pipe will expand if frozen and contract to its original shape when thawed. But putting frequent stress on the system weakens it, increasing chances of failure and leaks. So, to preserve the strength of your pipes, you should use the same standard insulation precautions with PEX to keep it from freezing.
How does the PEX home run manifold system work?
Manage control for all water lines throughout the home. Similar to an electrical breaker box, allows for central control for all water lines throughout the home. Innovative push-to-connect design makes for quick and easy installation. Minimizes the risk of leaks by eliminating excess connection points.
How does a PEX plumbing system work in a house?
A large-diameter (3/4 in.) main water line feeds the manifold; smaller lines run from the manifold to each fixture. Any fixture in the house can be shut off at the manifold. And because home-run systems don’t rely on a large pipe for distribution, you save both water and energy.
Where is the best place to install a PEX manifold?
The first step of installing a PEX manifold for heating is placing the manifold directly in the middle of the residence. This will allow for easy distribution of the PEX tubing to all areas of the residence.
Why do I need to turn off my PEX manifold in winter?
If the water freezes in your pipes, the expansion caused by the action makes it resistant to damage during the winter months. 2. You can turn off the water at a central location. When you’re trying to work on a specific fixture, you may find it necessary to turn off the supply before it enters your plumbing system.

How do you attach a PEX valve to a manifold?
With all of the holes drilled and the manifold mounted, attach the PEX ball valves to the manifold. Reach up, find the port and screw it into place. Get one of the lines and bring it up to the valve. This ensures that each fixture gets its own shut off valve.
How does a PEX return loop work in a hot water tank?
I imagine the easiest way would be a circulation pump on the output side of the hot water tank and before the viega pex manifold. each selected hot run (showers and faucets) would have a Tee below the fixture and a checked return pex line. then a return manifold on the supply side of the hot water tank completes the loop.
