marine boat toilet

[tinny tim]

Part 8 bolts to the underside of part 3 which directs the black water to the bottom of the pump which is pumped out of part 16 which is piped to the BW tank inlet

So are you saying that part 16 is the out let pipe and no outlet pipe on part 8

Part 13 connects to part 12 in the bowel flush and is connected to outlet on part 31.

The part 18 has an inlet that gets piped to the flush water tank or the the sea water inlet on a boat

But part 18 cant be the inlet can it?

Out of those 3 only one is a inlet hole or outlet hole

The right circle is not a hole the flange is used to bolt the head down to the floor

the one in between is also used to bolt the head down and not an inlet or outlet.

the other hole is a flush inlet just below when the pipe is from the pup to the bowl

Part has an inlet for water going into the upper pump that then is pimped out of the part 31

So is this the inlet whole; part 16?

 

[rogerthebodger]

No thats the black water outlet to the black water waste tank

Just below the No 18 is a inlet that the flush water goes in and is pumped out through the spigot on past 31 down the pipe 13 into the bowl through part 12

This shows the water flow directions

Only 2 holes.
1) flush inlet 19 mm dia
2) flush outlet 38mm dia

I replaced the pump with a electric diaphragm pump and a the inlet flush with a small diaphragm

it would appear that the 2 circels on the diagram are the 2 holes in question. But the waste one looks like it has 2 holes to it. one pointing up and the other pointing down

 

[rogerthebodger]

That is just alternate positions so the outlet pipe can be swiveled to suit the best direction of the outlet pipe to your waste tank

Look at the right hand pic it shoes the outlet pipe downwards as if your waste tank is under the head

So 38mm and 19mm right? Are they flexi or hard pipe?

So basiclly you can swivel it around to suit how you want it

The outlet you can but the inlet is fixed and yes they are hard PVC so be careful the stress / pressure you put on them when fitting any plastic pipe.

I use a heat gun to warm up the pipe i and fitting to make it easier to fit without putting too much load on the head spigots

While Roger googled a decent image I was sketching this... but I think you've worked it out now.

Sorry Kevin to beat you too it

Very good sketch BTW

Here you go, same make as your chosen khazi...

Sanitation and Waste Water Hose

Flexible, but the 38mm pushes the boundary of that description. It fights back if you try to get it to go round a corner!

It's costly stuff. You don't have to need too much of it and it will cost more than the crapper itself.

Will a 19mm compression fitting, fit on the inlet?
What about the outlet; is it hard or soft pipe

 

[rogerthebodger]

No use the pipes as posted by Angus in post #72 clamped with a stainless steel worm drive clips

I just want it to go into the floor boards and then stright into the tank. Would a 1 1/2" barb fitting bolted onto the tank do the job

 

[rogerthebodger]

Yes depends on what fittings are on th the tank

This would screw into a socket on the tank

Do you think this will work?

What about the 19mm inlet, is there room for a commpesion fitting to fit on the end of the pipe?

 

[tinny tim]

I guess you could boar out the hole your self really. But next question is; what kind of fitting do they use on the other side? for when they empty the tank. Where is it located, on the side or on the bottom underniegh

You'd normally just jubilee clip on a flexi pipe direct from your supply tank - in the same way as the pipe to the waste tank. In your situation filling that supply tank from rainwater might be an idea. In my strong opinion don't be tempted to connect the inlet to the toilet direct to your drinking water supply - these toilets use pressure and (perishable) seals and valves, back feed is not completely impossible.
