Install a 90-degree elbow and an MIP adapter onto the bottom of the water hydrant standpipe, using plumber's tape, tightening the fittings with tongue-and-groove pliers. The MIP adapter has male threads that attach to the elbow as well as a smooth (slip) socket that you will solvent-glue to the PVC water supply pipe. Install hydrant with drain hole below frost line. Use wrenches on supply line fitting and brass valve body only. This avoids over tightening the hydrant assembly which could affect operation. If supply line to the hydrant will not support hydrant, use re-bar, length of pipe or other suitable support driven in bottom of pit to help support hydrant. Using a backhoe or trencher, create a trench that is safely below the frost line from the supply to the intended location of your hydrant. Dig out a pit at the hydrant end that is roughly 3 feet in diameter and about a foot deeper than the level of the trench. Fill that bottom foot with pea rock or crushed stone to act as a small French drain. Herein, how does a frost free hydrant work? Frost-proof hydrants have been manufactured for decades. The water supply they are attached to is buried beneath the frost line and remains liquid. After the hydrant is closed, any water in the standpipe drains out, and the parts of the hydrant located above the frost line are completely empty.
I bought a 12″ Aqua dynamic Frost free wall hydrant (with Anti-Siphon vacuum breaker) from local Home Depot and it took an afternoon on the weekend to do it. It was easy but I was stupid enough to buy the wrong parts (plumbing thread types), so in order to save time and not to drive to Home Depot again, I decided to use whatever in my tool box and came up with an alternative solution – compression fittings and copper pipe soldering. The whole project took longer because of my mistake.
How To Install Frost Free Wall Hydrant
Honestly, if you don’t want soldering and don’t even want to work with PEX, buy SharkBite pipe fittings instead. Since I have all the tools when I worked on many plumbing projects in our old house, I decided to go this route mainly I have left over parts. But I bet SharkBite would be the quickest in terms of time.

Maintenance Instructions - Linkage Adjustment
The adjustment can be made with the water supply on by tightening the packing nut enough to hold the hydrant closed.
