toilet overflow connection to external pipe

[venablc]

I have an overflow pipe coming out of the bottom of my cistern which has a screw thread on it, i also have a pipe going through to the outside of the house approx 20cm away at a 45 degree angle from the cistern outlet. Any ideas how i can connect the two? i was thinking some sort of fexi pipe but can't find what i need

Any advice would be much appreciated!

p.s. both pipe are 22mm, the one coming from the toilet is threaded whereas the one going through to the outside is not.

Regards,

Chris V

Would this do the job?

Hi seco, the one going out of the wall isn't from anywhere, i drilled the hole, got the pipe but didn't consider how to connect to the actual pipe coming from the cistern

so at the mo i have the pipe going out through the wall, the pipe coming out of the bottom of the cistern but no way to connect the two

why did you do it so far away and at 45 degrees from the cistern outlet ?

is this a new toilet etc ? as you don't need external overflows now days

 

[venablc]

It's an old toilet which was put in before we moved in (not been in new house long) but the overflow was never plumbed up and it has no internal overflow.

As for doing it at an angle and so far away, that can be put down to lack of experience.

is it a lever type flush and not a push button flush ?

 

[dextrous]

Personally, I'd replace the flush mechanism with a new one with integral overflow (cost you about a fiver), and blank off the bottom overflow hole.

it's a lever flush, i did attempt to replace with a new mechanism which had an internal overflow but i was unable to find one which would fit in the cistern, they were all too tall

 

[seco services]

i bet its already got this and they haven't realised its got an internal overflow.

to tall you never looked properly then.

have you tried holding the float valve open and checking its not an internal overflow ?

you'll soon see when the water gets about an inch from the top of the syphon.

 

[venablc]

it doesn't already have one, the big puddle of water we found on the floor when returning from holiday can testify to that

I have two 90 degree connectors which i can use to get between the two pipes, the only bit which is really puzzling me is how to connect the the threaded pipe.

Is there any connectors which can connect a threaded and none threaded 22mm pipes ?

 

[seco services]

useally the overflow pipe pushes inside the toilet one and then a plastic nut does up on the thread and grips the over flow pipe.
and overflows 21.5 not 22mm

have you a pic of the inside of this cistern ?

 

[venablc]

Just ok a closer look and the overflow pipe is actually fractionally larger than the 22mm pipe i bought and the 22mm pipe fits extremley sniggly inside the overflow pipe

so i have just pushed it up inside about an inch (no pun intended) and connected the rest up with two 90 degree connectors and it does just the job.

I will use some putty to doubly make sure the connection at the cistern outlet is water tight.

Thanks for your help guys! didn't realise help was so readily available!

I'm looking for a sound solution to the above old-style WC overflow problem, posted as above by venablc 23 June 2009. The photo below shows my cistern overflow outlet which has a threaded c.24mm OD end collar.

It must join the c.22mm OD external pipe below, which can be pushed up inside the cistern pipe but any overflow then runs onto the floor through the small gap between the pipes. Anybody remember how that connection used to be properly made? I wondered whether the collar might have had a sealing ring that gripped the external overflow pipe and sealed the gap.
