All is well again, I do think there may have been at least a partial clog in the air line to the OC maybe that is all the trouble. I did have the return pump flow reduced down some don't know what that have to do with it tho. So all things being equal why do you think the water preferred the OC over the drain line does the valve in drain line give enough resistance to tip the flow down the OC which has no valve at all? I doubt it as I still had the same problem until I got my return flow back up.
