How to Vacuum Your Above-Ground Pool With a Hayward Filter

By Contributor ; Updated September 21, 2017

Hayward filter systems, known throughout the pool industry, are for many the standard by which other systems are measured. They are reliable and hardworking, with easily understood functions. Hayward filter systems come in a variety of sizes and styles, and use either sand, diatomaceous earth or a heavy-duty cartridge, according to the medium employed to filter and trap debris. The Hayward filter is also easy to operate when vacuuming your pool.


Empty both the skimmer and pump baskets of any debris. Any material trapped in either basket can reduce the water flow during vacuuming. Assemble your manual vacuum cleaning system, which consists of a 16-foot aluminum extension pole, a weighted vacuum head and a vacuum hose that is six to eight feet longer than the farthest location in your pool. The vacuum head attaches to the pole and the hose attaches to the hose adapter on top of the vacuum head. Lower the vacuum head and hose into the pool. Hold the free end of the hose and submerge it to evacuate any air pockets from the hose.


Fill the hose with water completely and attach the skim-vac that came as an attachment with your skimmer. Slide the hose onto the hose adapter built onto the skim-vac and place the skim-vac with the hose attached into the skimmer, resting atop the skimmer basket. Turn your Hayward multi-port valve to the filter setting and then, as you hold the extension pole, turn the Hayward pump on. The filter setting provides suction to the vacuum head on the pool floor and all of the larger vacuumed debris, filling the skimmer basket. Smaller items travel to the pump basket from the pool floor for trapping, while most of the other items flow into the Hayward filter, where they too are trapped. Vacuum the entire pool floor, removing all debris. If the pool appears cloudy, then concentrate the vacuuming in the center or in the particular area where leaves and other debris normally accumulate.


Turn off your Hayward pump and remove the entire vacuum system from the pool when the job is finished and the pool is clean. Coil the hose loosely and store it indoors to protect it from ultraviolet rays. Detach the vacuum head and store it and the pole indoors too. Take note of the starting pressure on your Hayward multi-port valve's pressure gauge prior to vacuuming. If during vacuuming, the gauge increases to between 8- to 10-pounds of pressure per square inch higher than the starting pressure, turn off the Hayward pump. This is an indication that the Hayward filter canister, filled with foreign objects to the point of restricting the water, needs to be backwashed to relieve the pressure before continuing. Backwash the Hayward filter by turning the multi-port valve to backwash and turning on the pump, which begins discharging dirty water from the filter canister. Continue until the water exiting the pool is clear. Turn off the Hayward pump and change the multi-port valve setting to rinse and turn the pump on for thirty seconds. This action settles the filter media back into the correct place. Turn the pump off, change the setting to filter and turn the pump back on to continue filtering.
