Hi

Can anyone offer advice on what might be happening here please?

In our downstairs shower room the water has always flowed fine since we've lived here (2 years) but recently the water has started to drain very slowly and fills up the bottom of the shower to the point where I have to stop mid shower, let the water drain away, then start again.

I've removed drain cover, grating and waste trap to clean (not really anything significant in there as far as I can see) but doesn't make any difference. Was worried it might be something wrong with the saniflo (recently had new replacement but it's not very easy to access to check) but bath seems to still drain fine. Funny thing is that I've now noticed if I take out the trap insert (inner white tube thing) it seems to drain fine! When I put it back in it flows slowly again. Not sure why this would be the case when it's never caused a problem before. When I look into the fitting where the trap insert sits there is a strip of plastic across the bottom that looks a bit knackered but I can't really see how that would make a difference anyway.

Any ideas please???

Grateful for any advice.

Thanks

H

Don`t see that you can do anymore at the shower end Helen and doubt the wet vac idea would be worth trying. Shame the Sani is difficult to get too as you could wet vac from that end at least you haven`t got the Sanimatic shower floor pump which was rubbish and has just been replaced hence my question in #12.
Different pumps start at different water levels in the tank so if the problem started as soon as the new one was fitted then that might be the problem. I mention this because of the washing machine which tells me that you should have the Sanibest but that model has a high ativation point. I seem to remember a post last year where the advice was to cut 10mm off the bottom of the tube part to allow water to flow away better but don`t do this until another member say`s so in case I`m wrong.

Thanks 'Pub Member' I too found that post about cutting 10mm off the bottom earlier before I wrote this post and did wonder. What does everyone else think?

Truth be told I am moving out soon anyway but feel bad about leaving this problem for someone else! Plus I could be here another few months before that happens anyway.

That's really nice of you 'village idiot' but I am Bristol based! Was planning to see what I could do on my own first before working out if I need to get a plumber in.
