Jetco 5 port 6 valve multiport switch or spider gasket in this sand filter might be leaking.
If I run the pump to full speed, water spoil out from the switch handle of the sand filter.
Pool water level also dropped 5mm per day see the last two photos.
But if I turn the handle from filter to backwash, all the water in sand filter will drop out then if I don’t run the pump, water level won’t drop from pool so it means the pool has no leaking, the leak is most likely in sand filter area or pipelines.
Please use the first photo to file the spare parts of the multiport valve and spider gasket then give me a quotation.
