We’ve owned our boat
a little over a year. One of the previous owners had the floor of each shower
redone in a sort of grainy, non-slip surface. I like the surface; it’s nice.
When they redid it, they apparently dropped some sort of insert into the drain that is attached to a 3/4” hose that runs through the old drain hose and to an aftermarket suction pump
that discharges directly overboard
. When showering, you have to flip on the switch for the suction pump
and you can hear it slurping and gurgling through the drain.
In this photo
of the drain, you can barely see the 3/4” hose insert under the cover plate.
The underside of the shower
drain is not directly accessible. However, a few inches away, it exits through a stringer and comes out here:
The original drain hose passes through another stringer:
When it comes out on the other side of the stringer, you can see it has been cut off and the 3/4” insert hose is coming out of the original hose.
It passes through a strainer and into a noisy, non-factory Whale Gulper pump before being discharged overboard
through a Y fitting, bypassing the sump pan entirely.
The sump currently only collects the gray water
from the sink and the a/c condensate.
Both showers have been modified to work
It works but it’s noisy and unnecessarily complicated.
I’ve spoken with other Jefferson owners and with a couple of mechanics who maintain Jeffersons. All of them say their showers drain directly to the sump, connecting through a Y fitting that also comes from the sink. No external, aftermarket pump.
Has anyone seen this modification before? Can you tell me more about the insert in the shower drain? (I have not yet taken it apart) Is there a compelling reason to leave it as is?
Any information would be helpful.
