I know this is an old thread but was hoping to revive it. I have a Jandy system and need to check the check valve since my spa level drops when the pump is off. I'm new to the pool and tried to take off the check valve cover and water was shooting out. I thought it was just in the pipes and would stop, but it didn't. I put the cover back on but am not sure how to check it without losing a ton of water. I would be grateful if someone could let me know how to do this properly.
