Pond Boss Forums AERATION Systems questions Problems with air delivery -Thomas 107CDC20/24

I am glad you found your problem!

They don't make'em like they used to!

Sounds like the manufacturer got a bad batch of reeds. And you proved that you're not going crazy. lol

The old design of the reed stop is a back-up plate with a rounded edge, the new style is a shorter nylon reed on top of Stainless reed that spreads the bend over a longer area instead of a very localized spot.

Augie: Hopefully you don't have any issues, your pump is different design if I remember correctly, but you know where mine came from. :-))

No wonder this was hard to troubleshoot-- TWO bad pumps. Very odd, but explains the symptoms. If nothing else you are now MUCH more familiar with your system and the normal pressures you should see at the pump discharge. A long and somewhat frustrating process, but knowledge and experience were gained. Odd that a new pump would have bad reeds. Congrats on figuring it out!

So far, so good here. I'm up to 6hrs/day run time with a strong boil for the duration.

I'm sure you'll be good with your pump style Augie.. I wish I was closer to REA, I'd change a few things but if nothing else I have an entire (upgraded) back up for every piece in the system.
