I agree it would be nice if DMCH sent out letters to their customers letting them know about these problems, especially after spending $400+ on something. I didn't know anything about this issue until Josh @ DPI posted about it on facebook.
Sounds like the problem is easily corrected with a check valve. Perhaps DMCH should send out a complimentary check valve to everyone who purchased one?
