Had a pool party and it was cloudy, drizzle, and cool. I let the heater run all day and the pool was a nice 90 degrees for the kids. I forgot that the pump kicks off at 8pm on the timer and the kids noticed the return jets stopped. The heater did trip off from the pressure switch. When I turned the pump back on, one of the kids screamed as hot water shot out of the returns (she was OK) and three joints on my plumbing starting leaking. Both o-ringed fittings coming off the heater were spraying and the PVC fitting going to my SWG blew out! I had to shut everything down and re-glue the PVC. The o-ring fittings are warped and won't seal. I had to use RTV silicone to glue the orings just to get the pump running again. At least it's leak free, but I need new fittings.
