Maybe installing a couple of joker valves would help, they are better
than the flapper ones. Admittedly they might eventially fail with hair
and other debri, thats why two. I don't think you have enough room
under the shower to install a sump, which is the answer. You never
empty a bilge pump line unless you are pumping downhill. Yes under way
close the thruhull.
Good luck.
