    We've just had a new toilet installed and the new toilet's waste pipe is lower than the cast iron soil pipe. My installer has used a flexi pipe to connect the toilet waste upwards to the soil pipe. Am I right to be concerned about the upwards connection, and the use of a flexi pipe? The cast iron soil pipe is about 1 inch higher than the toilet waste pipe. What might a good solution be?

    Need to raise the toilet

    That flexi isn’t acceptable either look at that sharp bend

    Get the installer back

    Thanks for your quick reply. When you say the flexi isn't acceptable, is that the silver clean water pipe?

    And by raising the toilet would that mean putting it on a plinth?

    Also, any thoughts on the use of the flexible pan connector? I've read a few things about them not being very good.

    Thanks

    Neither the Flexi water pipe or the Flexi soil pipe are acceptable.

    The soil pipe will block withing a matter of weeks, or even days.

    Yes too sharp of a bend (looks kinked) they tend to split when it’s done like that

    Yes or could you raise the floor ?

    There ok not the best tho but not installed like that

    We could raise the floor a bit - how much to you think it would need?

    I can't help thinking that we should have been advised to get a wall hung pan that could have been put at the correct level needed instead of messing with the floor level or a plinth!

    So that the outlet is at the same height as the inlet

    Thanks for your replies.

    If we can't raise the floor and I don't want a plinth, should I ask for re-installation with a different toilet, say a wall hung one that can be put at the correct height?

    I bought that toilet, however I did send the link to the installer first to confirm it would work and the installed had viewed the bathroom and said it was ok to order.

    TBH sounds like both at fault measure the height of the existing pipe off the floor what’s the distance ?

    Middle of the new toilet pipe is at 185mm above the floor not sure what the middle of the existing pipe is but the difference between the bottom of both pipes is about 25mm.

    To be honest this is the first toilet I have ever had installed and I had no idea that this was even a concern, I was relying on my installer to tell me what I had to consider in choosing a toilet that would work for my situation.

    Wall hung pan takes lot longer to install, don`t expect it for the same price as a floor sitting pan & cistern. Put it on a plinth and the kink in the braided flexi might also be removed by raising the pan & cistern.

    25mm plinth then.

    Thanks, any idea how long to install a wall hung one? My installer says this one took him 1.5 days!
