Hello everyone so I've just recently opened my pool and I've never had a problem until now. I have bubbles coming out of my pool jet. I've looked online and followed every tutorial from cleaning the skimmers, checking the orings, checking the pipes, checking the water level and letting the air out of my pumps everything seems to be fine. I've got no idea what to do anymore. Any help would be appreciated thanks. Also I have a cascade and have 3 different pumps for the jets and heater. Thank you
