I attempted to open my pool for the first time today, usually have a company open and close it but figured I would do it myself this year. Everything was going fine until i turned the pool filter on. Water had started coming out the return lines in the pool and then I noticed water was coming out of the heater rather steadily(from the inside). I'm attaching a picture of my filter/heater, anyone have any ideas? Also this piece was with all the plugs and baskets and I cant find where it goes, could it be why its leaking?
