For those of you who have an overflow swimming pool, they come with a balancing tank which is used for regulating the water level.
Did you know that after years of usage, debris and dirt can accumulate in it, resulting in high chemical use?
The foot valve as you see in the photo, is an item which prevents big items from being sucked into the pipe and into the pump – burning out your pump. It also prevents water from back-flowing back into the balancing tank when your pump stops.
It’s a good idea to have it inspected and replaced together with your pump check valves every once in awhile.
