Well last night after my bath ( I really wasn't that dirty I promise lol) i pulled out the plug and the nothing happened. We tried plunging (with the over flow bloked) several times to no avail. Later on the the washing up water came up in the bath. finally I put a load of washing on and the waste was coming up and down in the kitchen sink before being mostly emptied into the bath. Now Im stuck with a blocked kitchen sink (which I cant use) and a bath full or brown liquid. Toilet seems to be working fine and bathroom sink. Any ideas?
