The pump is the heart of a swimming pool filtration system. The Association of Pool and Spa Professionals publishes standards for swimming pool circulation. Residential pool pumps are required to have sufficient pumping capacity to turn over the entire volume of the pool every six hours. In the average residential pool, this requires a circulation rate of 36 gallons per minute; that’s a heavy load on the pump and other system components. It’s no wonder malfunctions and system shortfalls occur.

Pool pumps are installed below the upper water level of the pool in pump pits or underground compartments. Water is gravity fed to the pump inlet when the pump is off. Once the pump is energized, the inlet line is under suction and the pump outlet, including the filter and return line to the pool, is under pressure. Anything that disrupts that harmony may result in loss of circulation, even though the pump is physically operating.

The strainer basket inside the pump chamber is the last-ditch filter to stop debris from entering the impeller of the pump and damaging it. Debris that slips past the skimmer strainer collects here. If it’s not regularly cleaned, a full strainer eventually may obstruct water from reaching the pump and interrupt circulation. Cleaning out the strainer basket according to the pump manufacturer’s instructions may be all that is required to restore flow of water through the system.

A neglected main pool filter may obstruct circulation entirely. This normally is preceded by a noticeable rise in the filter pressure as indicated on the gauge atop the filter canister. Filter manufacturer’s specifications include the normal pressure range for your filter. If the pressure displayed on the gauge is high, backwashing the filter according to the manufacturer’s procedure may remedy the problem. If the filter is too contaminated to respond to backwashing, emptying the sand or diatomaceous earth filter media, and replacement with fresh media may be required to restore full circulation.

Your pump does a great job moving water, but it’s not effective at pumping air. Air infiltrating the system from various sources may accumulate in the pump chamber, where it creates an airlock and prevents sufficient water from reaching the pump to “prime” it. The system then lacks enough suction to pull water through the lines and expel the air. All air leaks have their origin somewhere before the pump on the suction side of the system. If the water level in the pool has dropped below the skimmer intakes, the system will draw in air. Restoring proper level in the pool should cut off the air. Another common cause is a leaky O-ring in the removable pump chamber cover.

Manually priming a pump may be required when other methods fail to remove air from the lines and restore circulation. The procedure for priming most pool pumps is universal. With the inlet and discharge valves closed, remove the pump chamber cover and fill the chamber with water from a garden hose. To ensure all air is removed from the system, the air-bleed valve on the filter should be opened. After the chamber cover is installed, and the inlet and outlet valves opened, the pump is energized. The added water primes the pump and jump-starts the suction process, which begins pulling water from the pool and expels air. The bleed valve on the filter also releases air as water fills the filter. When water begins spurting out of the bleed valve, the valve should be closed.
