MortarThePoint Posted Thursday at 11:49 Posted Thursday at 11:49 I'm using a McAlpine CON8E and it connects up nicely except my soil pipe is too high relative to the tiled surface meaning the connector's pipe section doesn't have a fall. In fact it slopes slightly the wrong way. If I raise the toilet up on 5mm packers, this pipe section is level. Ideally I'd want a fall of about 1:40, which would mean having the toilet 10mm above the tile. I can't change the height of the soil pipe as it is all boxed in so I'm wondering what to do? I think the spigot on the toilet is lower than it says in its dimension drawing (180mm) and the tile build-up is thinner. I've attached some pictures of the situation and then a single picture of it with 5mm packers under the toilet.

I can't see infill of 10mm looking awful, so go for that. I guess you may have to plug and re-drill the holes for the cistern, risking tile cracks, but (unless I have missed something) that looks like being your worst potential problem. Do you have a couple of spare tiles?

Do you have a couple of spare tiles? I haven't drilled any holes for the toilet screws yet so that wouldn't be an issue. I do have some spare tiles. Are you thinking I could create a low platform for the toilet to sit on?

I do have some spare tiles. Are you thinking I could create a low platform for the toilet to sit on? Yes and no. The spare tiles were in case you cracked the existing when drilling. The 'platform' could be made of anything. 9 or 10mm ply or cement-board cut slightly undersized so that you can 'point up' with silicone. Equally if the tiles are c 10mm and you like cutting tiles, use tiles, again undersized and pointed. Re the fixing of the cistern, I have a sneaking feeling that one of mine (they are all close-coupled) never got fixed to the wall anyway, with no disastrous effects. I'll go and have a look later! 1
Russell griffiths Posted Thursday at 12:30 Posted Thursday at 12:30 Flush it see what happens IMPO the whoosh of the pan emptying will send all stuff well past that pan connector, then gravity takes over with a bit of momentum from the flush. nothing will come backwards. 1
markc Posted Thursday at 12:37 Posted Thursday at 12:37 +1 @Russell griffiths as long as it’s only the connector with no fall you will be fine, fall along the run is to ensure everything keeps moving along.

May mean I have some waste water permanently sat in the connector against the seal to the toilet pan. Isn't that a concern?

Isn't that a concern? Actually, thinking about it there is often going to be some water there since the toilet spigot is larger diameter than the pipe section 1

Isn't that a concern? Only if it leaks, mcalpine products don’t leak if fitted well. what’s your other choice, don’t pack the toilet up more than 3-4 mm it will look proper turd. 1

MortarThePoint Posted Thursday at 14:45 Author Posted Thursday at 14:45 By measuring the height (107mm) above tile to the underside of the MAC-8E's 'trumpet spigot flange' and based on a crude measurement of the MAC-8E drawing's 'trumpet spigot flange' O.D. (136mm) I get that the spigot height of this toilet is actually 175mm (107 + (136/2)) not the 180mm it's supposed to be. That's the main route of my problem. The tiling is also likely a tad thinner than expected, but the spigot dimension is the main issue.
