Welcome to our forum.
Actually, I did hear a humming noise from the ozonator. What would you advise? It's not as if I can order another nipple right? Would I have to order a whole new ozonator?
The ozonator is definitely humming. I put a small hose clamp around the hose just below the black plastic screw-on adapter that keeps the hose connected to the nipple. The hose is now just as tightly fit to the nipple as before. I think it should be good from here. Thank you both for your assistance. When I do swap out the check valve, do I just pull off the hose on each side of the existing one? It seems very tight.Thanks!
