So it would be best to replace the whole control valve? It may or may not be important, but there seems to be no trace of any type of silicone or anything where the spider gasket is supposed to sit. Also, is it hard to replace the control valve? My husband is a truck driver and I usually try to tackle these types of projects myself. And if I were to try to just do the gasket, is it someting I can purchase anywhere or is it a pool store type item?
Thank You
