Herein, how do I start my pool filter?
Simply so, how do pool pumps and filters work?
Does the pool pump go before or after the sand filter?
When installing the pool sand filter, you will connect it right after the pump. Pool water will come in through the pool pump, be filtered through the sand filter and released to the chlorinator before returning back to the pool.
Plug in the pool pump and cover it with a weatherproof cover. With the main service off to the house, wire in GFCI circuit breakers to the electrical panel. Connect an 8-gauge wire to the metal posts of the pool, the pump, and the metal plate on the skimmer and then wire that to the pump to bond the entire pool.
The “Filter” setting circulates water through the sand or DE media, then out the filter through the return port to the pool. This is the standard setting for normal pump and filter operation. The “Backwash” setting redirects the flow of water backwards through the filter media to flush out contaminants.
