any plumbing experts here?
Got a bit of an issue with a flush pipe - it keeps working its way loose and the best suggestion so far is to replace it with a flexi (worked a treat
for the soil pipe)
only issue is the original is one of these:
https://spares.thomasdudley.co.uk/concealed-cistern-spares/vantage-cistern-spares/pspfwh322326.html
which tappers from 51mm OD to 41mm OD
it actually measures more like 49.9mm OD (45.7mm ID) at the cistern end which is a push fit
and at the pan end it measures 43mm OD (39mm ID) which is a fairly tight fit into the rubber connector - which it seems to be lifting off the bottom
of the seal off the pan and working / walking its way loose..
so the plan was to use something like this:
https://mcalpineplumbing.com/plastic-chrome-fittings/flexible-fittings-non-return-valves/flexcon5c-flexible-fitting-universal-x-plain-spigot
https://mcalpineplumbing.com/sites/default/files/uploads/drawings/Flexcon6.pdf
but as to the best way to connect it at the cistern end and which size is which (some sites are quoting different sizes for the same fittings )
I'm pretty sure too short get the flex on the end of the smaller diameter of the existing flush bend - so the best bet would seem to be using the
flex to do the bend, then use some sort of adaptor onto the larger diameter coming down from the cistern
any thoughts / suggestions of what to buy ?
Hi,
You shouldn't need any sort of flexi-pipe between the cistern and the pan. It sounds more like something is miss-aligned. The pipe into the pan /
rubber should be a really tight fit, should need lots of Fairy Liquid and pressure to get it to enter. It only has water in there during the actual
flush, it doesn't hold water at any-other time. Has your cistern dropped or the pan moved and caused the alignment of the flush pipe to move ? A
new flush pipe, with new washers and seals, should be all you need. The few mill difference between manufacturers and cisterns will easily be taken
up. If you still not sure // confident, a make an extra "washer" from some well kneaded Plumbers Mate and apply that.
If you do go for an alternative to the fixed / solid flush pipe I can thoroughly recommend McAlpine fittings, they were the first manufacturers whose
fitting would "fit" any other makes / material of waste pipe. Since discovering them 35years ago I have refused to use anything else.
Might a block of wood or plastic between the pipe and the wall prevent it moving back and coming out of the toilet end?
Sorry should have said, its a wall hung toilet, so its definitely moving a tiny bit every time its used
I've stiffened it massively already, so the flex is as small as possible, but it'll never be 100% solid
It's not from Victoria Plum is it? i had problems with leaks and a dodgy seal, i wouldn't use any washing up liquid, only water or
saliva.
Check the length of pipe as it may be slightly longer or shorter and when you use the pan it moves the pipe from the seal slightly.
