How To Install A Frost Free Hydrant

Posted on

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.

Frost

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.

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.

Woodford Yard Hydrants INSTALLATION INSTRUCTIONS

Install

(These instructions do not apply to Sanitary Hydrants or Utility Hydrants)

  1. Dig hole for hydrant approximately 2 feet in diameter and deeper than the bury depth.

  2. Flush gravel, debris, etc. out of the supply line before connecting hydrant.

  3. 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.

  4. 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. Before filling excavation, turn on water and check hydrant connection for leaks.

  5. Provisions must be made to allow the water to drain from the hydrant drain hole each time the hydrant is closed. (a) If the hydrant is installed inside a structure or concrete driveway, connect 1/8' copper drain tubing to the drain hole and dig a remote drain field outside the structure for the drain pipe to empty into. Without this remote piping drain field, the water from the hydrant drainage will percolate up to the surface around or near the hydrant and will damage the floor surface or cause muddy areas around hydrant. (b) Saturated ground in the hydrant drain field can prevent the hydrant from draining and may result in freezing. If the area where the hydrant is located is low lying or has a tendency to have standing water, a larger drain field or pit may be required to provide the hydrant a place to drain. (c) Fill bottom of pit with 1/2' gravel to a level about 3' above brass drain valve body, to insure adequate drainage.

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.

W34 & X34 To increase the tension: With the hydrant in a closed position, loosen the set screw in the side of the pivot. Lift the handle, which should lift the linkage without moving the stem, to the desired location and reset the set screw.

To decrease the tension: Lift the handle part way open and loosen the set screw in the side of the pivot. Lower the handle, which should lower the linkage without moving the stem, to the desired location and reset the set screw.

The handle, at the end of the closing stroke should 'snap' closed.

Y34 & Y1 To adjust the linkage, remove the lower link bold that connects the lower link to the clevis assembly. Loosen the set screw in the lower link. Turn the lower link out (counterclockwise) to increase tension and in (clockwise) to decrease tension. The handle, at the end of the closing stroke, should 'snap' closed. Tighten set screw. Install lower link bolt.
