My partner very kindly blocked our loo 3days ago. After moaning at him to sort it with no avail, I Googled it and successfully unblocked division myself. Now however, toilet paper won't flush down, everything else will except the paper. Any ideas why?

Because you only partially unblocked the drain... there is still a restriction that needs cleared... either chemically... or snaked by a plumber if that doesn't work.

Welcome to The Plumbing Page at AMHD.com. Try this. Purchase a closet auger and auger 0ut the bowl. (see images) good luck, Tom
