Aft Shower/tub drain line

[rebuckley]

Does any one here believe that the aft shower/tub drain hose ever fully empties into the sump - I remeber something about water running downhill better than uphill from school. It seems that the drain hose goes "up" to reach the sump.
I am thinking a "sump box" in the stern by the shower may be a much better method to ensure the "stinky water" goes away.

Has anyone done any modifications here? (I thought I had read something like this but cannot find it again)(1982 36 DC Trawler) Any good suggestions for "sump box" locations? or photos?

Thanks -
Reb

Hi Reb,

Would you consider one of these new pumps from Whale?

Does away with the sump and is small enough to mount close to the tub. Should eliminate any water in the drain line.

They also make a shower version where the "intelligent control - IC" is built right in to the strainer, but that wouldn't work for a tub.

I just installed a Johnson shower sump, input from the shower pan in the aft head. The tub is too small to use. I routed the output to "T" in the aft sink drain. Pump is automatic.
