Ok first off this happened several months ago so I feel I am ok but.....
My kids were having swing lesson at around 10AM. I leave with baby sitter and swim teacher (20yr old girl). I come home around 2-3 and my kid says I think the pool is getting too hot because it is bubbling. I look outside and the swim teacher removed the vacuum cleaner and put it outside the pool. This was about 4 hours later. The water was bubbling out of the ports.
The pump has been working fine since but at shut off it shoots a small squirt of water out of the seal. I also noticed the water pressure went from say 15-20lbs.
The season is about to start and if there is going to be an issue I would rather do it now. Could the pressure just be a coincidence?
