| I have had that experience with the snotty stuff in suction line of Dosatron. There is a check valve in the bottom of the Dosatron that gets some of that snot in and I think it keeps the check valve from sealing. I also have a check valve of my own installed in the suction line but once in a while I still experience what you are saying. Clean the check valve at very bottom of Dosatron. Not a very heavy spring in it also. | |
