Fitting advice for 2-in-1 Combination toilet/basin

[davhill]

Good evening all,

I bought a combo potty with basin from Bathroom republic via eBay and I'm about to set about fitting it.
It was advertised as a 'Beth' toilet - I think it may be Chinese and there is no maker's name to work with (pls see pic).

In the cistern is new fangled (to me) hardware. It consists of a ballcock unit and a cable operated flush
device. There are various coloured plastic tabs, clearly for adjusting things. I also have a Couts & Louis?
monoblock mixer tap but no waste as yet. I think a clicker would do nicely.

Here's the plan! There's a vertical 110mm soil pipe to tap into. I bought a 110mm FloPlast strap boss, (68mm
stub) and I'll solvent weld this on to the soil pipe. I have one of those rubber reducers (Flexseal 110 to 68) on order
so the black water side should be covered.

Now for the innards. The ballcock unit clearly has a cold feed at the base - this goes through the bottom of the cistern.
On the side of the unit is a threaded stub (probably 3/4BSP) that is 25mm above the cistern's 'floor' and seems the
obvious place to attach the cold feed for the tap. I expect I'll have to add a 90 dgree connector.

OK. There are also two white Nylon connectors (pls see other pic) that are clearly meant to fit through the cistern floor.
I'll run the hot and cold feeds in this way. I'll be using pushfit piping and will put an isolating valve in each feed.
This leaves only the connections to the monobloc. The push flush button's fitment is obvious. All the threads match.



So, has anyone come across a similar setup or can anyone point me towards some instructions? Lastly, am I in the right parish as
regards the above?

Thanks in advance,

David

Am I missing something why do you need to add a strap on boss ?

the second picture is a blank put the cap on and it keeps the water in the cistern/ tank

Assuming the pan outlet is 68mm (unusually narrow, but if that's what it is - ) you make sense as far as I understand you.

Best advice is dont. Absolute pile of poop.

Best advice is dont. Absolute pile of poop.

Which incidentally is what you’ll end up with if you try and connect a toilet via a strap boss...

 

[gmartine]

Not seen that before and not sure how you'd use it safely as per the pic. What, straddle the bog or bend over and do your back in?

 

[Ric2013]

Are you sure the pan outlet is only 68mm, OP? They are normally about the same diameter as the soil pipe itself, so this sounds very odd.

Unless you're thinking of reducing the pan outlet down to 68 in order to use a 68mm connexion? Which would simply be wrong. You'd need to cut into the stack and fit a proper 110mm connexion to accept 110mm pipe and then connect to the WC pan outlet with a 4" (or whatever) pan connector in the conventional manner.

Ric, I think op was going to put a strap boss on the 4” and then connect to the outside of the boss with a fernco reducer to get it back up to 4” - clearly this is very very silly.

I have actually fitted a similar contraption 10 years ago and it did the job well, it did have a 100mm spigot as normal - I’m sure this one will too.

Thank you gentlemen,

You've understood me. I was planning to use a 110mm strap boss with a 68mm O/D
stub and a 68 to 100mm Flexseal cuff to attach the pan's 100mm outlet to the soil pipe.
As this is clearly not on, what sort of connector do I need, please?

Many thanks, David

A pan connector to 110mm
