Although am very careful about grease not going down the sink, I am finding just the greasy water from washing up is causing blockage in waste drain. What have you good people found to be the best to clean the tank out. Many thanks.

Well today I put 4 litres of cheap cola down the sink and went for a spin to slosh it about. I then open waste drain and when it drained out loads of bits of fat and sludge came out. I then boiled a kettle and a saucepan of water, put it in a bucket with Fairy liquid, added a small amount of cold water not for it to be boiling and do damage, and poured the jot down the sink. Another drive around for a slosh, and when I opened drain loads of fat and sludge came out. I will do another session but I think I have cracked it.
