Installation Instructions for Any Flow® Series Yard Hydrant
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 water line on which hydrant is to be installed has been thoroughly flushed to wash out foreign particles.
Merrill Manufacturing™ will not warrant or accept any responsibility if the water line is not flushed out prior to attachment of
hydrant.
Step 2: Be sure the hydrant is installed with provision for drainage below the 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 the ground and no tile are used, be sure to put a quantity of gravel, crushed rock or some coarse
material, not sand, 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 this 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 water line, just turn it onto the male thread connection for which it is intended. Merrill
Manufacturing™ has hydrant ells and tee fittings available for connection to flexible poly pipe.
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, refer to the adjustment
section for the proper adjustment.
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 adjustments below. Merrill Manufacturing™ will not accept any
responsibility for digging up the hydrant if the installer fails to flush out the water line before attaching hydrant to water
line andto check the 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 could restrict water flow or may make the hydrant inoperative.
CAUTION: If the hose is attached to the nozzle of the hydrant when hydrant is shut off, back siphoning can occur if end of hose
is left in container of liquid. The end of the hose must be left open to the air so hydrant can drain back.
