i will never do it again to much troubles to find all the impeler piece in the cooling system.

Sorry for the delay on booster pump. Had a high speed miss similar to clogged pump I had expierenced before.
Cleaned it and didn't go away.
If you have never had your booster pump off, do it and check for debris on the little screen. I found a lot of crap, metal bugs etc. Fountain needs to put a piece of tape over the tanks on the shelf.
