A few years ago I had a problem with my March sucking air into pump. I figured that out as it was air bubbles forming and getting trapped beneath the FB and getting sucked into the pump as the HERMS heated the water.
Since then I've put together a new system which has been running flawlessly since last august.
Now I haven't been brewing on it for the last two or three weeks, and I'm all of a sudden getting air.
If I run MT - pump - MT, it works nicely, if I run MT - pump - HERMS - MT, I'm getting air. Everything has gotten new teflon tape, and I've swapped hoses around, opened up the pump, but it happens after ten seconds when running through the HERMS, I can run without the HERMS with no problems. I can't see a single bubble of air in the MT. The HERMS-loop adds some restriction. FB is not installed when this happens.
Anyone know what might be going on here? It's just cold water. I haven't touched a thing, it just magically started to happen.
