I just add an old towel and few carrier bags round the loo brush (tied on tight), when I did it, but it turned out the drains were blocked from my neighbours man-hole and had backed up to ours!

Don't be as clever as me Val, who decided to put hot water in the cistern and flush it through. It cracked and we had to have a new emergency toilet... a white one (with a pale blue suite)>>>>>>>>>>then a completely new suite!
