Soil stack question

[huw169]

Hi all
I have 2 toilets on the same stack - one up stairs, one down stairs.
I need to remove the downstairs toilet for a few weeks while work goes on. What can I use to block up the opening so it doesn't smell, and i don't get any 'splash out'??
Been hunting for something on line & in B&Q, but haven't really found anything suitable.
Thanks
Huw

You need a drain bung.

Not common at B&Q .... try a proper merchant

I'll give you £3 for one posted Nige?

The drain blanks that stop off unused plastic chamber outlets are ideal.
