My bath has one of these levers that you press to get the plunger to go down. Last year the people downstairs complained there was water through their ceiling. I went back to the bathroom company and they gave me some reason that if you jumped in the bath quickly it can cause it to go down the hole but it would work if the taps were left on accidently. ARe they telling me rubbish as it doesn't sound right to me. Does this bath sound like it has an overflow or not. I cannot see a reason for a company omitting such a vital thing.
