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
 
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?
 
Who bought the toilet ?
 
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.

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

1.5 days for what ?
 
What’s going on the floor ?
 
1.5 days to install this new toilet - see front pic attached
So install new toilet pan & cistern to existing pipes - Yes?
Wooden boxing around new toilet -Yes?
Replace basin & taps in original postion -Yes?
Remove existing flooring?
Any other work? Lights & switches?

Yes, everything, but 1.5 days was in reference only to installing new toilet pan & cistern to existing pipes, everything else took extra time and cost.

Erm, where did you find this plumber. Was is a local website such as Mybuilder? Guess he hit the problem and couldn`t figure out a better way of getting around said problem.
Did they say nothing at all to you about it before they left, take it you`ve paid them and they aren`t taking your calls now.
