I replaced the two diaphragms on my Pond Master, before winter. My kit didn't cost that much and the aerator is only a couple years old, so it was worth it.It's not the stones @Meyer Jordan - we replace those twice a year. The air isn't coming out of the hose at the stone end at all - I tested by removing the stone and sticking the end in the water. Nothing.
@Tula - I did a little reading and it sounds like it just might be the diaphragm. They say it can appear the unit is pushing air, but as you get farther from the pump it doesn't have enough pressure to go through the hose and stone so it escapes back through the bad diaphragm. Unfortunately the replacement part is almost $30 on a $90 unit - I think it's time for a new aerator.
I think I'll look into a piston driven aerator, next time I have to replace one, as they're quiet and don't have a diaphragm to fail.
