Installing a holding tank - Installation, Days 2 & 3

It was a bit of s struggle getting hoses on, even with lots of hot water, but I got there in the end.

There is a "Y" junction bottom left leading to the
seacock,  the holding tank outlet pipe going behind
the bowl, the direct outlet is waiting to be cut and
connected to the diverter via the anti-syphon loop.
The green pipe is for the automatic bilge pump
Getting the diverter straight and fixed to the panel
was the biggest struggle mainly due to lack of
room plus stiff pipes and pipe connections that
would not rotate (with jubilee clips slack).
The finished job. The board left is a drop down table,
rarely used now that I wear a beard so don't need it
shaving using the mirror out of picture right. If I
venture into the Baltic or some other areas I will
have to put an eye on the panel to "lock" (probably with
a cable tie) the diverter to feed to the tank as is required
in places to prevent an accidental discharge.
The holding tank and filter fully plumbed in, the breather goes
to the chain locker as there is insufficient freeboard to put it
through the hull without a high risk of getting water in the filter.
The Henderson Mk 5 pump in position with the ball valve left.
All plastic components are by Trudesign, the seacocks are genuine
bronze (not  DZR Brass)  by "Blakes". The pump is capable of
emptying the tank in less than 30 seconds. Lots of jubilee clips,
 doubled for all connections below the water line or hidden are
needed for piece of mind and to keep surveyors and insurance
companies happy.
The hatch, installed when I converted the forepeak to a wet area
had to be butchered, I can still get my spare washboards in the
locker but I'll have to find somewhere else for the spare tiller. For access
I'll need to keep this area reasonably free of obstructions so things I might
 need quickly or regularly are going to live in the locker.
All together it took about 3 days but I had the advantage of my work some years ago replacing the original vanity unit and installing panelling and the electric conversion to the toilet.

Servicing the clean water input side of the unit,
the output side was not as straightforward.
As I was working in the area a deep service on the 5 year old macerator seemed to be a sensible idea, unfortunately it as not straightforward; two slot headed machine screws were unmovable, I ended up bringing it home, drilling off the heads, disassembling, bending the 650mm M5 machine screws through c 90 degrees and using the bend to get leverage to free them after applying lots of penetrating oil. 

Fortunately nothing was damaged so it only cost a couple of bolts, lots of swearing, several hours and a "wasted" visit to the boat when I tried to do the service whilst on board.
