View Full Version : DoS head losing prime

03/18/2017, 11:33 AM
Any advise before I send message to Neptune directly. I have 2 DoS pumps, 1 of the 4 is losing prime. I've removed and re-seated the clear tubing and still loses prime. I can actually watch the magnesium go back into the bottle.

Any advise?

I'll update when I get info or trade from Neptune
