Salt water pool filter not working.

Hello susie the pump may not be getting enough water when you connect the pool cleaner. Chlorinated water leaves the canister in a hose that connects to the main return line after the filter. A salt chlorinator cell not working causes the water to become murky and dirty with time and most sane people wouldn t touch it with a ten foot pole. Under sized swimming pool filters and pumps having too small of a pool filter pump motor will cause the pump to work harder and it won t be able to filter the dirt out of the swimming pool.

More often than not the problem is with the salt cell and not the entire chlorinator system itself. If the unit has plunger valves make sure they are open. There s around 3 000 ppm parts per million salinity in a saltwater pool. This could mean an obstruction dirty pool filter or too much air getting into the plumbing system.

Put simply a salt water pool is a pool that has been chlorinated by means of salt chlorination and not traditional harsh liquid or solid chemical chlorine. Circulation line is blocked. In other words it has lost its prime. Switch the diverter valve back to half way between the skimmer and main drain.

In this situation something has interrupted the suction or the water flow that causes the system to work properly. A malfunctioning salt water chlorinator is every spa and pool owner s nightmare. Clear dirt and debris from filter cartridge and cell. If the pump is still not primed check the impeller for debris and filter pressure for anything 10psi above the clean reading for your pool filter.

Commercial pools may do it a little faster. The key is to just slightly open the main drain because opening it too far can cause the cleaner to get stuck on the drain. If water is not flowing freely in the strainer box return to step one and repeat. You can try opening the main drain line so that the pump can get more water.

Make sure filter pump is attached and is operating. Normally a residential pool filter pump should turn over the water at the most every 8 10 hours. Electrolytic pool cells are often mistakingly referred to as salt water filters but they in fact don t filter anything they convert the existing salt in your pool water into low levels or chlorine through the process of electrolysis. If the chlorinator was inadvertently installed with these hoses reversed the injection.

Release all trapped air in the circulation line. By comparison there s 35 000 ppm in the ocean.
