THE AREA LEAKS BETWEEN
THE HEADERS AT THE PLASTIC
PANEL CLAMPS
1. PPC latch is not tight enough to
seal the joint.
Slide the latch farther across the
connection between top and bottom
half of the clamp.
2. PPC is not seated squarely in
grooves.
Disassemble PPC and verify that the
gasket is seated properly.
THERE IS A PIN HOLE LEAK IN
ONE OF THE RISER TUBES
1. If it’s a new installation, it may be
a manufacturing defect.
Contact your distributor for warranty
repair information.
2. Riser tubes are rubbing on roof
surface.
Contact distributor for a repair
kit and adjust the spacer bars to
prevent future damage.
3. Birds or squirrels have damaged
the tubes.
Contact distributor for a repair
kit and adjust the spacer bars to

THE 3-WAY OR BALL VALVE
WILL NOT TURN
Internal parts need to be lubricated
or replaced.
If the valve has a grease fitting, turn
it clockwise to inject grease into
valve then turn the diverter past the
grease fitting to spread the grease.
If the grease fitting is dry, fill it with
silicone grease. If there is not a fitting,
disassemble valve and lubricate with
silicone grease. Replace worn or
broken parts.
THE AUTOMATIC CONTROL
SYSTEM IS NOT WORKING
Various
Consult the manual for the automatic
system you have.
THE WATER COMING FROM
THE SOLAR SYSTEM IS NOT AS
WARM AS IT SHOULD BE
1. The water is flowing too fast
through the panels.
Test the water flow rate. Water flow
through a single panel should be less
than 10 gallons per minute. Adjust
the 3-way valve to bypass some of
the water.
2. Seasonal normal operation.
In the cooler months of the year,
or on cool, partly cloudy days,
temperature rise through the panels
may only be 2° or 3°. Use the back
of your hand to feel the water
temperature difference at the pool
return inlet.
