If you switch to wipes, for god sake don’t flush them down. I, er someone I know, did that a bit to vigorously once resulting in a blockage. No amount of flushing or liberal use of a wrong size plunger would shift the beggars.
Ended up calling a plumber in. A bloke who looked uncannily like Ed from Shaun of The Dead turned up. Whipped the u-bend off the sink, and shoved a long cable spooled around a drum thing, then attached a drill and gave it the good news. Cured the blockage, only problem being the speed of the wire turning flung the weeks old excreta of previous customer’s endeavours up my bathroom wall 
He wiped some of this off with a manky old towel (no gloves) then flung this into his work tool bag and left.
Still, cured the problem, but lesson learnt. Don’t be a lazy ■■■■
