Fairline Weekender 21 Toilet

[RogerBarnett]

Hi everyone.
I'm very new to this and new to boating too. Not sure if I'm posting this question in the correct forum. I have a Fairline Weekender 21 and would like to know if the toilet uses seawater or fresh water to flush? There is no holding tank. Does anyone know?
Help appreciated.
Many thanks.
Roger.

It could be plumbed either way, but all the boats I've been on used salt-water.

On my boat the hose supplying water to the head is obvious and you can follow it through the engine bay to a seacock.

Some have a marine toilet so will use whatever the boat is floating in, seawater or fresh, to "flush". Does it have in/out seacocks through the hull?

Some have a chemical loo in the heads compartment...

Almost certainly uses seawater. The toilet in the first video is a pretty standard Jabsco sea toilet which draws in water through the 3/4" pipe at the bottom of the pump and expels it through the large 1/ 3/4" pipe at the back. Follow those pipes and you will find the seacocks - probably in some hard to reach place. The second video boat has a chemical toilet, presumably because it is on inland waterways.

Inlet and outlet seacocks are both under front port side berth. I blocked off the outlet and put a new holding tank in the engine room, front port corner, with pump out fitting through the deck directly above, and vent out the stern next to the fuel tank vent.

Thank you all very much indeed for your replies. I shall investigate the pipework this weekend and all should become apparent.
Thanks again.

I have a weekender and as KDee states in his reply inlet piping is under port side berth. mine has switchable Y valve to dump sewage either into holding tank on portside in engine bay or overboard.
Flushing water is drawn onboard from the water source your on either sea or fresh water.

Hope that helps

almost all toilets like this, use the water taken through a skin fitting in the hull. It will then either be pumped directly overboard or through a y pipe with valves to select either a holding tank or overboard. hope that helps

Many thanks for taking the time to reply, it really is much appreciated. Does the boat suck in the sea water from the outside then, ie, endless supply of flushes? Or, as QBhoy says, does it use the water taken from the skin fitting in the hull, ie the fresh water I fill the boat with?

 

[Blackgang boy]

Roger a skin fitting is the name given to any fitting that passes through the hull ( Skin of the boat, hence name) from the inside to the outer hull.
This therefore gives you an endless supply of water for flushes, but if you have a holding tank for the discharge (usually fitted if operating on a river or lake) then you will eventually fill it, whilst at sea you will discharge all waste through a skin fitting over board into the sea.

Hope that makes things a little clearer.

I was meaning it takes water through the skin fitting in the hull, as in takes water from outside the hull..as in the water the boat is sitting in..hope that helps clarify.

Oh I get you... Many thanks for explaining, much appreciated. All the best.

Clear as a bell. Many thanks for explaining Blackgang boy.
