Do you have your fill/drain hose towards the front or rear on your bags? Updated the pumps to reversible and plumbed the hoses to the front, thinking the rear would be better.

I have the Fill / drain to the back, the pump has no problem pushing water in, having the inlet in the rear allows the bag to drain better as it gets lower. If the pumps loose prime during draining the bag wont drain all the way.
I have the Vent on the top opposite the fill side because as the bags fill that corner is highest in relation to how the boat sits.
Having a hard time getting the back ballast bags to drain all the way. It isn't a timing issue. I thought I read on a previous post (can't find), that people added something to the pump or line to help drain the bags. Suggestions?
I put ball valves in the vent line, open when filling til they spill out the port, then close them. Keeps them from continuing to siphon out the vent, and when draining they drain completely with no air at all in the bag.

Thanks Shoebox! Do you recall where you got them?
A quality marine check valve in the vent line will aid on a more complete drain. Totally passive, no opening locker to do anything for fill or drain.
check valves work great.
