My waste drain keeps blocking up, help!

by Jan Harlott
Spent £75 last month having it unblocked by a plumber and don't really want to have to do this on a regular basis. I stop using recycled paper as plumber says this cannot break down so easily. The blockage is (I suspect) same as last time outside the house before it gets to the junction. Help
