Sink draining very slowly yet U-bend is clear, etc

just pumps · 16 Oct 2018

Very little fall so the bottom half of the pipe will be fat, oil & grease, still say loads of very hot soapy water.

Thanks, I'll give that a go.

Buster pipe unblocked works (as well as any other). Little Black /Blue bottle, buy 2.

Thanks, is that any better than Mr Muscle ?

just pumps · 16 Oct 2018

I believe so

Actually Kilrock now do one and their products are normally first class.
Yellow and Black label, widely available.

Thanks both of you.

If those dont work, for goodness sake be careful if trying to do anything else with it, and warn anyone else who may work on the problem.

This is your last pair of eyes.

Noted, will do.

I'm trying the drenching with very hot water and fairy liquid approach first though.

Plunger? Pressure can sometimes loosen things up, but failing that I'd still go for mechanical methods over chemical.

I do have one of the long flexible waste pipe cleaners on order, just hope it doesn't break the plastic pipe as it goes around the bends.

You could do with measuring the fall on that waste pipe (is it a kitchen sink or a hand basin? Recommendations are different- sink should have min 40mm dia waste, fall between 18 and 90 mm/metre. Washbasin min 32mm (max run length 1700mm), fall between 18 and 22mm/metre)).

still a lot of info missin but as someone said above, cut the waste pipe 75mm - 100mm from the outlet wall. an then run a K45 pipe cleaner down it - no hit orr miss or chemicals ( i hate them) involved.
also after cuttin, drop the trap an bit of pipework an clean it out.

you can hire a K45 or get a plumber who does drain cleaning in to do it.

I've now dumped a load of hot soapy water down the sink and it's definitely draining better now. Not perfect yet but I'll do that a few more times and keep my fingers crossed that I can avoid chemicals or pipe cutting.

Thanks all.

fair enough but you said in first post that it keeps happenin?
whats i'm suggestin will be a once and for all unless your dumpin grease an stuff down the waste?
