    We do that. I have a gallon jug. I collect the first gallon or two from the water maker run, clean but not drinkable. Then we use that water to fill the bowl before doing that business.

    This is the T under my sink. It is similar to Jesse's. The white line goes to the head raw water intake. The black line comes down from the sink. Close the seacock. Put water in the sink. Flush the head wet until the sink is empty, then flush dry to push everything into the holding tank. No connection to fresh water tank or lines. If I can do it, anyone can. I was once told I should never use tools without supervision.

    I did this on Saturday. Boat is on the hard so I didn't get a chance to try it, but I think it will accomplish my intended goal and it only cost a few dollars. The hardest part was getting the hose to make the bend up into the vanity. I was going to re-purpose the Tee that the head intake and shower/fridge sump shared, but it was a tee with three threaded fittings, opted for a one piece barbed tee. West marine only had plastic, but the guy said it was suitable for below waterline.

    Thanks for the tips, sure was easier than adding a second water tank ;-)

    One of the biggest bang for the buck jobs I've ever done on a boat.

    I think plastic below the waterline is not a good idea. You CAN find metal tees- hardware store or Home Depot IIRC. I just used one for the tempering valve. I think that bend in the drain will slow or not allow normal drainage. My drain goes 2' downhill to the seacock, and it takes almost a full sink of water to overcome the bay water resistance. my 2 cents.

    Unless it's gray water, why are you flushing sink water out the thru-hull instead of flushing it through the toilet?

    I didn't think it a good idea to put soap, detergent, or anything else that might end up in the sink into the holding tank. I thought I read that somewhere.

    In regard to emptying the sink via the seacock: No issues on my boat, works just fine.

    You did...at least one of the dozen or more times I've posted it. :D Which is why I said "Unless it's gray water..."

    Thank you Peggy. Everyone who has a head on their boat should have a copy of your book (and read it). I keep mine handy
