Almost NO Reason to Ever Dig up a Hydrant to Fix a Leak
Under no circumstances should Merrill Manufacturing™ Yard Hydrants drain back into well or drinking water
supplies!
*Merrill Manufacturing™ disclaims all liability of any kind and voids the hydrant warranty for installations of this
product where it can or could drain back into a drinking water supply.
Step 1: First be sure line on which hydrant is to be installed has been thoroughly flushed to wash out foreign
particles, rocks and sand.
Step 2: Be sure the hydrant is installed with provision for drainage below frost line.
If hydrant is installed in a pit, the pit must have an open bottom or some form of drainage.
If hydrant is buried in the ground, a few tile can be laid in gravel or coarse material to form a field system for
the drain.
If hydrant is buried in ground and no tile are used, be sure to put a quantity of gravel, crushed rock or some
coarse material around the drain of the hydrant. This will permit faster and better drainage.
Step 3: Important - If hydrant is buried in the ground it is a good idea to put a brick or large stone under the hydrant,
because when the hydrant drains and the subsoil becomes wet, it will allow the hydrant to settle and thus put a strain
on the pipe to which it is connected. A brick or stone would carry this weight.
Step 4: To connect the hydrant to the line, just turn it onto the male thread on the bottom of the valve body, for which
it is intended.
Caution: When the hydrant is tightened, be careful that it is not tightened so tightly that the hydrant head or
valve body will be screwed further onto the pipe and thus change the adjustment of the hydrant. If this should
happen, adjustment on the hydrant stem rod can be made by turning the two nuts, refer to the adjustment
instructions below.
Step 5: Important - Before backfilling the trench, turn on the water. Then turn on the hydrant by raising the handle
to let the water flow. If the hydrant is not working properly, refer to the adjustment instructions below. Merrill
Manufacturing™ will not accept any responsibility for digging up the hydrant if installer fails to flush out the water line
before attaching hydrant to water line and to check hydrant for proper operation before backfilling the trench.
WARNING: If the ground freezes at or below the bottom of this hydrant, your warranty is void and damage due to
improper installation or act of nature is not covered by manufacturer.
CAUTION: Use wrench on valve body and fitting only! Do not use wrench on this stand pipe! Additional tightening
or loosening will change adjustment of hydrant and restricts water flow or may make the hydrant inoperative.
CAUTION: If the hose is attached to nozzle of hydrant when hydrant is shut off, back siphoning can occur if end of
1/4
