Ok, at first it was taking a while for my bath (which has electric shower) to drain when ever I had a bath/shower. I decided to carefully lift the tiles and followed the pipe (strange direction, guess out of everyone's way) I then noticed that the pipe was practically sitting on the floor so I therefore corrected the level, put all my pipes back and it was draining brilliantly.

Then about a week later the bath has started gargelling when I flush the toilet. I should have mentioned that I took the pipes from the bath apart to see if they were clogged and I put them back together. I have done the same with the sink. I have not attempted the toilet pipe. I live in the top floor flat. I have also had my front driveway tarmaced this week and am starting to wonder if this is the problem, however, I looked down the manhole and it seems OK to me. I guess all the evidence leads to the toilet being the problem but it still manages to flush everything away, however, when it flushes the water level rises quite high before falling below it's previous level once finished the flush cycle. A tiny bit of water spits out into the bath when the toilet is flushed.

Having looked through the internet, I have tried, pump. Coat hanger and just went to B and Q to try One Flush(strong chemical) and after following the instructions I don't think this has fixed the problem. Does anyone know what I should do? I had phoned a plumber for advice and he had said try One shot. I know that nothing untoward has been put down the toilet. Please help people I am going insane!

why does bath gargle when toilet flushes?
The tub talks to you as the toilet flushes because the toilet's venting through the tub trap insteaed of the vent pipe. This indicates a clogged vent. Snake the lavatory vent from the roof. Put out enough snake to reach the base and 20 feet more. Good luck, Tom

Do you mean the pipe that goes outside and then verticle from the bathroom? Thanks for the reply.

That's the vent. If it comes out of your bath room that's the one to snake. Good luck, Tom

Im also having similar issues with my washing machine. I rent and whenever my washer drains off the water, the tubs and sink between the washer and the septic tank spit our a little water(gurgling) I would assume my washing machine vent is plugged correct?

Stop where you stand, if you rent ask your landlord to rod the vent or to call a plumber. Most LL don't want their tenants trying to repair anything.
