Hoeptner Freeze Flow Sanitary Yard Hydrant Installation Instructions

Freeze Flow hydrants are designed for heavy-duty commercial use where safe potable
water is needed. This hydrant drains into the canister below the frost line to prevent
freeze ups and cross contamination with the soil bacteria
INSTALLATION
1.) Hydrant canister must be placed below existing frost line. Figure1
2.)
No ground preparation is required for the Freeze Flow Sanitary Yard Hydrant; therefore
it can be placed in any soil condition. Hydrant canister is stainless steel and pipes are
all galvanized steel, which meet ASTM specs.
It is still the responsibility of the installer to know his/her soil condition and to ensure that
proper corrosion protection is administered to the hydrant. The application of paint or
rubber tape may be needed to protect against some soil conditions.
3.) Flush supply lines BEFORE installing hydrant.
4.) Attach hydrant to existing supply line using an approved thread sealant.
5.)
BEFORE back lling with soil, perform a Shut O Valve Leak Check to make sure shut
o valve does not leak due to debris in supply line or damaged o-ring. A leaking seat
can cause hydrant to ll with water and possibly freeze.
Shut O Valve Leak Check:
Remove back ow preventer at quick disconnect (Figure 2)
Operate hydrant at partial ow with thumb over outlet until the
water pressure forces past thumb. (Figure 3).
At this point shut o hydrant.
[ With hydrant full of water it is easier to detect if hydrant is leaking. Hydrant
should not drip from outlet once hydrant is full of water. ]
If hydrant leaks from outlet, remove operating rod and replace o-ring on stopper tip. (Figure 4)
6.) If no leaks are detected then replace back ow preventer and proceed to back ll hydrant with soil.
