Reversible ballasts draining during use

[j.mo]

In my Supra my bags fill, and drain from the same hose and discharge beneath the boat.
The rear are draining during use.
Worn out impellers?
I can’t put a wakemakers check valve, because then they would not drain.

Impellers would be the cheapest troubleshooting option and the most likely reason for draining.

I have some new ones in the glove box. I’ll give ‘em a swap and see.

not sure of your set up but is there a vent line that goes out the side of the boat for overflow when filling? If so, sometimes you can get some draining out if the bags are completely full and you are listed to the side.
