To install a Wirsbo EP Manifold, you need a Wirsbo Expander Tool with a 3/4" head and a 1/2" head. 3/4" PEX-A tubing can be attached to the supply and return ends of the manifold, and 1/2" PEX-A tubing to each outlet.
Wirsbo manifolds, tubing, tools, and fittings can be found at www.supplyhouse.com
