Toilet Cistern Pipe Fitting

[Del 80]

Now that the downstairs toilet is fitted, the time has come to connect the permanent water supply to it.......the thing is when I connected the temporary supply, I over tightened the conex fitting, and partially stripped the threads of the plastic pipe at the bottom of the close coupled cistern.......is there an extra long female fitting ? with more threads on it, that I can use ?.......

Use a inlet with a brass thread not a plastic thread.
I stick to same brand as thread length can vary making swapping a problem as you need to adjust pipework to couple.

fluidmaster are good

If you have stripped the thread on the float valve ,fit a new float valve. As said above ,one with a brass tail.

Thanks for the replies.......it's just the very bottom of the threads, I just wondered if there was a fitting with longer threads that I could use......either brass or plastic...... the toilet is working at the moment, with a temporary feed, on very low pressure, but once connected up properly it will be full pressure, and I can't see the fitting holding..........it might be a dumb idea, but I did wonder if I could cut say 1/4" of the bottom of the float valve feed ? thus allowing the connector to "bite" the threads........

Bin the plastic rubbish off, as said, brass tail every time.

For the sake of £15 why muck about?

Brass-tailed valve all the way

Mmmhhh....this might do the job......as long as the threads on the inlet are 3/4 BSPF........anyone know ?.....the other end is a 15mm compression fitting.......

 

[Del 80]

Or this ?......I'm using JG Speedfit anyway.........

Thread is 1/2in BSP on virtually all float valves,never 3/4.

O.k...Thanks for that.....just measured it again......18mm.......it's a Portland close coupled toilet, from Wickes......

 

[terryplumb]

The diameter has nowt to do with the thread size. 19mm diameter will be 1/2 inch BSP thread.

 

[Del 80]

Ok, Thanks.....so if I go for the Speedfit one, do I want 15mm x 12mm.....or 15mm x 19mm ?.........

 

[terryplumb]

I have no idea what fitting/s you are looking for, but the end that connects to your supply pipe needs to be 15 mm if it's a 15 mm pipe. The other end Needs to be 1/2 inch BSP female thread.
Why don't you just fit a new float valve as I ,and others , have already advised ?

 

[Del 80]

Thanks for that.....it's only the very first few threads that are damaged, so I might get away with it, if not then a new float valve is in order.......

 

[Del 80]

Well, all is not lost......it turns out that the threads are O.K, and with the correct fitting, it tightens up no problem.......the fitting I was using was an old "Prestex" one that I found in me shed.....not one of my best ideas !!......
