Hello All -
I’m getting ready to start the plumbing work on my NS36: new sinks and faucets (and all the plumbing attached to them). I’m wondering why it wouldn’t be ‘nicer’ for the shower sump and the ice bin sump to simply tee into the through-hull drain underneath the counter rather than the countertop whale faucet that is used? Is the water line too high to make a loop under the counter?
Thanks -

the ice box floor, the through hull and the shower sump are below water line. Even with a loop above the waterline you would need a siphon break.. I think you will need a new separate pump to drain the ice box. You will also need shut off valves near the shower sump and the ice box drain to keep standing water out. On the 26 if I forget to close the sink drain through hulls when I am sailing water will come into the sink. If you forgot to close the through hulls and did not have shut off valves to the ice box and shower sump there is a risk water would come over the loop and back into the ice box and shower sump. Once water started flowing it would continue flowing even if the boat is no longer heeling unless you had some type of siphon break.
Now I get to sit back and find out why I am wrong.

Hi Bob,
The boating industry solved this problem for you. Several brands make a “shower drain box”.
Whale GW0500 or Rule 99B or others. They feature enough inputs and one output.
In my N36, a Rule version of this box is installed under the floor, right in front of the toilet door. The icebox drain, the toilet countertop sink, the showerfloor drain and even the mast compartiment drain are connected to its inputs. The output of the box goes to a breather that is mounted under the countertop in the bathroom. It’s kinda midships and well above the waterline. It then goes to the thruhull that was formally used for the toilet countertop sink.
The sink of the kitchen goes overboard via it’s original thruhull because of debris that gets flushed in this sink that might clog up the drainbox pump.
hope this helps
