• If the hydrant leaks just after installation, the valve seat may be
fouled with debris, such as small rocks. The operating pipe

• A small leak may be the result of a leak at the drain hole.
Replace the plunger if it is old and worn. See
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.
• 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

• The O-ring seal in the diverter may be damaged or pulled loose
from the groove. Use a pair of needle nose pliers, stuck into the
outlet of the diverter, to remove the diverter. Inspect for damage
or reinsert the O-ring into the groove. Replace the Diverter
#15238 if necessary.
• If water will not flow through the backflow preventer with the
diverter pulled down, the backflow preventer may be obstructed
or damaged.
Remove the backflow preventer and inspect for obstruction or
damage.
