Repairing A Leaky Outdoor Water Hydrant


Hydrant interfaces

How you interface your outdoor water hydrant will depend more on where it fits in the outdoor line than on the pipe material (assuming it’s poly). Use T-fittings on in-line runs and elbows on end-of-the-run installations.  Buy and assemble the best fittings you can afford.  An investment now will save maintenance, costs, and labor later.

Installing hydrants

Installation for both in-line (using T-fittings) and end-of-the-run hydrants (using elbows) is basically the same.  Follow these simple tips:

Plumbing Pro Tip of the Week

Tip #1  Tape the interface fitting threads with Teflon tape;

Tip #2  Screw the fitting into the hydrant;

Tip #3  Slip the pipe on the fitting, and secure it with two all-stainless clamps on each side;

Tip #4  Set the hydrant in the trench, drop a bucket of gravel around the drain hole, and fill in the ditch.

Tip #5  To keep an end-of-the-run hydrant turned in the right direction, make the turn with the fitting, not the pipe.

PLUMBING TRADE SECRETS:  When taking the lines to the hydrant through a concrete or block basement wall, punch out a hole for a PVC pipe slightly larger than the water line pipe.  Use the PVC as a sleeve through the wall to protect the water line pipe from abrasion.  Once in, caulk all around the joint to prevent water intrusion.

WHAT CAN GO WRONG:  Just remember that this protective sleeve is not enough to prevent freezing.  Other measures will have to be taken to protect the water line pipe when temperatures dip below freezing.
