Project Log: Friday, April 4, 2014
After a light sanding, I applied another coat of gloss
varnish to the back side of the head door. I also
sanded the door frame itself, but didn't get back to
varnish it before I had to leave for the day.

Next on the agenda was to get going on the final
connections for the head and sanitation system,
beginning with the plumbing. I'd collected a
variety of fittings and plugs that I'd require to
complete the task. To recap, since it's been some
time since I last discussed the system, recall that this
is the Raritan Hold 'n' Treat system, incorporating a 15
gallon holding tank and salt water-based waste treatment
plant with automatic or manual operation. I'd
installed the self-contained system in its space during
an earlier stage of the project.
First in line was the discharge elbow for the treatment
unit. A PVC elbow with one smooth and one threaded
side was supplied with the kit for this purpose, but I'd
needed to buy a threaded pipe-hose connector in order to
attach it to the flexible discharge hose. After
installing the adapter, I dry-fit the elbow so I could
mark, and then drill, the adjacent bulkhead to allow
passage of the hose. |
 |
Afterwards, I prepared a short length of hose to pass
through the bulkhead; the other end of the hose
connected to a joker valve (check valve), which was
supplied with the kit, and was designed to prevent
cycling of the discharge (macerator) pump. |
 |
From here, I'd connect to the hose that led directly
overboard, but I'd forgotten to purchase a siphon break;
with the whole system perhaps barely at the waterline,
this would be a prudent installation. Fortunately,
my appointment later in the day would take me near my
supplier, so I'd be able to pick up the device and
continue working later in the weekend.
Meanwhile, I installed threaded PVC plugs on all the
unneeded ports provided in the holding tank, and
installed an inlet elbow and bushing with vent fitting
in the two ports needed for my installation, then
connected the discharge line from the head itself, and a
new vent hose, which I ran into the locker outboard of
the head compartment. |
 |
To complete the vent, I installed a typical screened
vent fitting through the hull, and connected the hose
within. |
 |
That was all the time I had for now, but I'd continue
forthwith. |
