10 and 20 port Quick connect manifolds for use with PEX, copper and CPVC. Full flow 1" CTS (Rigid copper tube size) inlet and outlet ports can be reduced to 3/4" with 1" x 3/4" reducers (included). 1/2" CTS (copper tube size) Quick connect (push) outlets with 1/4 turn ball valves for quick control of each line. Manifolds can be deadheaded by leaving the end plugs installed or used as a return loop using the return loop end (included). Manifolds can also be placed in series by installing 6" pieces of 1" PEX, copper, or CPVC pipes into each inlet/outlet of manifold. Preinstalled mounting kit allows manifold to be securely fastened. All 1/4 turn outlet ports use the patented Watts Quick connect collet and O-ring guide design. Manifold should be located in an accessible area but can be concealed behind a finished wall with access. Manifolds include: Preassembled 10 or 20 port 1/4 turn outlet valves, 10 or 20 individual label plates for fast circuit identification, (1) 3/4" x 1" reducer, (2) 3/4" end plugs, (1) return end, and instructions. Faster, easier connections, includes shut-off valves and more versatile as it can use PEX, copper or CPVC than the manibloc type manifold.
