Y34 & Y1 Yard Hydrant
Rev 08/10 Form No.TMYH-1.103
1. Water leaks from the nozzle when the hydrant is off.
• Check the closing force of the handle. If the handle does not
“snap” closed at the end of the closing stroke, see
Linkage
Adjustment instructions.
• If the hydrant leaks just after installation, the valve seat may be
fouled with debris, such as small rocks. The operating pipe
assembly will have to be removed and the hydrant casing
flushed. See
Operating Pipe Assembly Removal instructions.
• To inspect and/or replace the plunger if it is worn or damaged,
see
Operating Pipe Assembly Removal instructions.
2. Water leaks around the brass stem below the handle linkage when
the hydrant is on.
• The Packing Nut will occasionally need to be tightened to stop a
packing leak. Tighten the Packing Nut until snug and the leak
stops. Persistent leaks will require a new Packing #10101. See
Packing Replacement instructions.
3. Water leaks from below ground level when the hydrant is on.
• A small leak may be the result of a leak at the drain hole.
Replace the plunger if it is old and worn. See
Operating Pipe
Assembly Removal instructions.
• A large leak may be the result of a hole in the pipe casing
caused by electrolysis corrosion. Some soil conditions can cause
premature failure of the pipe casing near the valve body. Brass
pipe is recommended for these conditions. Contact the factory
for details.
4. Hydrant will not drain when shut off.
• Make sure there are no attachments on the nozzle, such as a
hose or vacuum breaker.
• Improper linkage adjustment (not enough tension) may prevent
the hydrant from draining properly. See
Linkage Adjustment
instructions
• A poor drain field around the valve body or a blocked drain hole
will prevent drainage. See
Yard Hydrant Installation Instructions.
