Moving along

Lately the focus has been on finishing up loose ends.

A wash-down fixture was mounted on the foredeck and tied into the water pump for the toilet inlet. The toilet inlet water pump does three jobs now; provides water for the toilet, the deck wash-down, and a faucet at the head sink. There is no discharge  thru-hulls anywhere near the intake so their is no threat of contaminating the incoming water. The head discharges directly into the holding tank and is pumped overboard from time to time when permitted, or drawn thru a deck suction fitting when required. 

I plumbed a tee into the toilet discharge line and took it up to a deck fitting so that when pumping the holding tank the deck cap can be removed and a water hose used to flush the holding tank.

A ball valve was placed on the discharge side of the holding tank  and a macerator pump was plumbed in.

I got the pump from a customer who wanted a replacement pump as he considered this one to be too noisy.

I took it apart and cleaned, sanitized, and rebuilt it, put in new check valves and installed it my boat.

The disassembly and cleaning was a thoroughly disgusting job as there was a significant buildup of foul deposits that needed to be scraped and picked at to remove them from the orifices. Even though I saved a few hundred bucks on the pump I don't think its a task I'd care to repeat!

A two way valve was installed and the discharge line plumbed into it. From there one side of the valve went up to a deck suction fitting and the other through a vented loop to the overboard discharge thru-hull.

The last connections were made to the holding tank vent and filter and now the toilet system is finished and operational....although not tested at this time. It feels good to have another system completed and struck from the "to-do" list.
