6.2. WATER PROBLEMS
WATER DOES NOT ENTER PAN, OR ENTERS SLOWLY
Cause Solution
Mainline or valve frozen.
• Install heat tape onto mainline to prevent mainline
and valve from freezing.
• Properly insulate waterer box and caulk around bot-
tom of the base to eliminate cold drafts.
Valve bottom may have obstruction
restricting water flow.
• Remove valve from pan, inspect, and if necessary,
clean out bottom half of valve of any obstruction that
may be present.
Top portion of valve may be over-tight-
ened to bottom portion (causes dia-
phragm to rest directly on top of zytel
seat; for proper flow of water, tolerance
should be approximately 1/16” between
diaphragm and zytel seat). • Back pressure off of the 3 valve screws, empty bowl,
and allow pan to refill. Water should seep out sides of
valve (between the diaphragm and bottom of the
valve). Retighten screws only until the seeping stops.
This will ensure proper function of the valve.
Plastic plunger is frozen to inside of
valve top.
• Check water level. Float arm may need to be
adjusted to ensure proper water level. Excessive or
improper water level will detour proper function of
waterer.
Pressure in water system is inadequate
to service waterer(s). Recommended
water pressure: 40–50 psi.
• Service pressure system to ensure adequate pres-
sure.
• Note: Excessive water pressure will cause seepage.
Do not exceed 40–50 psi. If excessive water pressure
is present, use an inline flow restriction regulator
device to ensure adequate pressure (at pressure sys-
tem).
Float may be frozen to side of float
cover.
• Ensure float is centered in float cover. Valve may
have to be turned slightly to achieve this.The float
must move freely up and down (in centre of float
cover) to function properly.
VALVE FAILS TO SHUT OFF AUTOMATICALLY AND WATER LEVEL CONTINUES TO RISE IN PAN
Cause Solution
Foreign matter (sand or grit) may be
lodged between diaphragm bottom sur-
face and zytel seat preventing proper
sealing of diaphragm.
• Turn water valve off. Remove 3 screws from valve top.
Clean bottom side of diaphragm and zytel seat. Exam-
ine zytel seat for pitting. Replace zytel seat and/or dia-
phragm if damaged. Retighten screws.
• If your water source continues to bring up particles,
you may need to install a strainer filter in your pump
house to remove any particles.
Float adjustment may be too high. • See Figure 4.1 for water level adjustment.
