Troubleshooting
PROBLEM.
CAUSE
SOLUTION
THERE ARE AIR BUBBLES IN THE
POOL WHEN THE SOLAR HEATER IS
OPERATING
1.
If the pump is making more noise, there
may be air coming into the pump through
an air leak on the suction side of the pump
due to the pump working harder to move
the water through the solar system.
A.
Be sure pump trap lid is on tight.
B.
Check the “O” ring on the pump trap lid.
clean, lubricate, or replace as needed.
C.
If you have a suction type pool cleaner,
remove it. If this improves the air bubbles,
only use it when not operating the solar.
D.
If you have a clear lid on the pump and
can see air bubbles in the trap, run water
over the lid and each joint individually to
see if the air bubbles will clear up using a
garden hose. If there is not a clear lid, listen
to pump noise for a smoother operation,
repair any air leaks.
2.
If the vacuum breaker is installed on the
roof, there is not enough water pressure
in the solar system to keep the vacuum
relief valve closed and it is allowing air to
be drawn into the water as it flows by the
valve.
A.
Be sure filter is clean. Backwash to
reduce pressure.
B.
If it’s an older system, check for debris
or scale in the mouth of the vacuum relief
valve and clean if necessary.
C.
Use the
2-way valve
on the return line to
throttle the flow back to produce more back
pressure on the system.
