Pan Connector lower than Soil Pipe

[GrantMcscott]

Hi

We have 2 soil pips that come straigh out of the wall and were set for having tiles on the bathroom floor.  We have now changed to LVT in the bathrooms meaning the soil pipe is 15mm higher over a distance of 200mm.  

 

Will this cause me an issue or will I need to ply out the bathroom floor to raise it?

 

thanks

You mean the soil pipe is already higher than the pan connector?  or are you saying you "only" have a fall of 15mm over 200mm?

It's not going to go uphill

Sounds like discrete a plinth under the loo pan might fix it

I would rather ply out the whole floor than a plinth

or go back to the original plan of tiles?

yes could do.  May give it a try and see what happens plumb it in and raise it the 6mm for the LVT.  see if it leaks or blocks

You will need a pan connector anyway to fit into the soil pipe, so you might try an offset one like this

 

 

It would in effect increase the depth of the U bend in the WC and still leave the outflow going down hill.

 

No doubt a plumber will come along now to say why not, but I did this years ago in a previous house to line up with the outlet that was a cast iron pipe cemented into the house wall which i did not want to replace.

That’s designed for vertical fit offset not horizontal

Will give it a go it will raise the water in the pan a little but testing will see if it is an issue 🙂

Can you fit a wall hung toilet? - extra height shouldn't be an issue then.

Ready got the toilets and would need to take wall out to put in frame for wall hung.

I am not a plumber (but have done loads), using that will leave a small amount of water permenantly against the seal but as long as it’s good it will work (it’s what I would do.)

What are you measuring …?? You’d be surprised that the WC pans aren’t all equal and I would measure to the inside of the bottom lip of the pan and do the same for the soil pipe. That will give you your true offset.

 

If laying LVT I would just glue and screw down a layer of 6mm ply and then LVT over that, pan on top of the lot. If you need any more height then use another layer of LVT under the pan cut slightly back and then a decent sealant bead tooled properly would cover it anyway. That gives you 18mm and a downhill connection.

Measuring centre of the pipe.

Water flows on the bottom of the pipe - start there with measurements.
