How to Build a Sprinkler Manifold With Six Valves

Cut a piece of PVC pipe into 5-inch sections. You need at least seven pieces this length.

Apply a thin coat of PVC cement to the outside edge of the first piece of pipe. Use enough glue to cover an area at least 1-inch from the outside edge of the pipe.

Press the glued end into a "T" fitting. The top hole on each fittings will be where you install each valve. Make sure your T-fittings have pipe thread on the inside of the top hole.

Apply a coat of cement to the end of another piece of pipe, and press that end into the other side of the T-fitting.

Apply a coat of cement to the end of the pipe that you just installed, and press another T-fitting over that. It's very important to align the top holes on all of the T-fittings so that they all point straight up and are aligned.

Repeat the process of applying cement to pieces of pipe and pressing them into T-fittings until you have six T-fittings in a row, plus one section of pipe sticking out of each end.

Apply a layer of cement to one of the end pipes, and press a PVC cap into the hole to seal that end of the manifold. The other hole will be used to connect the water line to the manifold, so leave it open.

Screw in each valve into the holes on the top of each T-fitting. Use valves with built-in pipe thread connections that are 3/4 inches. Hand tighten each valve so that they are firmly set in the T-fittings.
