TROUBLESHOOTING
1. Air entering your filter is dangerous and can cause the lid to separate. Correct any conditions in
your filtration system that allow air to enter the system.
Some common ways to identify air entering the system:
a. Low water level in pool or spa - skimmer is starving for water with pump running. Add
water to pool or spa.
b. Air bubbles or low water level in pump hair and lint pot are caused by; low water level,
clogged skimmer basket, split suction cleaner hose, leak in pump hair and lint pot lid, or
leak in pump suction line.
c. Air bubbles coming out of water return lines into pool or spa with pump running.
d. Air is discharged from the air relief valve on top of the filter when the valve is opened with
the pump running.
2. Until the water initially put into the pool has been completely filtered, short filter cycles in
between cleanings are normal. In most cases pool owners are dismayed by the undesirable color
and appearance of water in a newly filled pool. Plaster dust can be responsible for short filter
cycles, requiring frequent cleaning.
3. If pressure drops on gauge, check skimmer basket and pump basket first for debris. If the
baskets are clean, shut off power to pump and turn off any automatic controls. Then turn motor
shaft with your fingers. If it turns freely then the pump must be disassembled and the impeller
checked to see if it is clogged. If it is not frozen or clogged then there is an obstruction in the line
between the pool and the pump.
4. The pressure gauge is an important part of the filter system. It is your primary indicator of
how the system is operating. Maintain your pressure gauge in good working order. Check the
operation of your pressure gauge in the following manner:
a. The pressure gauge should go to zero (0) when the system is turned off and pressure is
relieved.
b. The pressure gauge should indicate pressure when the system is operating.
c. The pressure gauge should be readable and not damaged in any way.
d. Replace the pressure gauge if it does not meet the requirements above.
