Custom Flush Pipe High Level Cistern

Postby Hiven88 » Fri Apr 15, 2022 5:20 am


I’m trying to replace an antique high level cistern with a more modern ceramic one. The flush pipe is routed in a very specific way so the new one will probably need to be bespoke.

Does anyone have any experience, or at least seen, bespoke flush pipes? I was hoping they could be made from standard off the shelf copper tubing (needs to be metal for aesthetics), rather than me needing to buy the chrome flush pipes they sell with the cistern and bodging it to make it fit.

Any insight would be appreciated to know if this is possible. Companies don’t seem to list what size the flush pipe would be or if an off the shelf diameter would also work.

Hi hiven88,
Usual size is 1 1/2” diameter so you would have to find some 32mm copper tube and a company with suitable bending equipment. You could use a standard plastic hi level flush pipe, heat it to bend to the shape you want and spray paint it with copper paint.
