Bathroom sink

[HarryHornby]

Oh focer font of knowledge - another "before I foc it right up" question:


I want to replace the tap on our bathroom sink.  The sink is probably 20 years old at least and was in the house when we moved in.  Ideally we should replace the bathroom but cash does not permit this yet.


On the current sink the automatic plug thing that you control from the taps is long focced so I'm looking to replace it with the new taps.  The one I've got from Wickes comes with a new plug section.


My question is about removing the current waste from the sink.  I'm guessing it's simply been silicone sealed (or similar) into place in the sink and once the ubend has been disconnected I can "push" it out from below using a "little" force and patience.  Would this be right or is there normally something firmer holding these things in place never to be replaced, ever?!


Cheers

It should come out with a little (as we say) fazer elbow grease.
A big tip for you when fitting the new one is to use one of these http://www.diy.com/departments/plumbsure-plastic-rubber-basin-sealer-dia32mm-set-of-1/178380_BQ.prd
I fitted a new sink last year and the pop up plug waste came with great looking silicone rubber seals that I was sure would work, but after a couple of hours - sure enough it started to weep as they all do down the thread.
I then used the basin sealer in the link, which was supposed to be used without any extra sealant but that too dripped.

So I refitted with the basin sealer in the link AND added silicone sealant in between all surfaces and now no more drips, I think that pro plumbers always use extra sealant because that is the only way to guarantee that they wont be called back with drips.   

Dont use the crappy foam rubber washer that comes with the popup waste but instead seat it into a bed of silicone in the sink.

Cheers Mr Sharp,  just as I suspected re removal, just wanted to check.


For a couple of quid that seal looks a winner, and as for silicone sealant, I'm no plumber, so any job I do involving water gets plenty of that (or PTFE tape) used

Heres a fitted photo of the one I did last year. the only part I used that came with the waste was the nice brass backnut 
Silicone between the white plastic part and black rubber cone and on the cone to sink area where you can see the white silicone and also around the thread and inside rubber cone mating area

Google Basin sealer or basin mate for better pictures and a utube help too

i think it depends on the quality of the fittings as to whether it leaks or not.
a 9.99 waste will always need sealant........others don't

As you can see by the fact that my waste came with a brass back nut it wasnt a cheep one and the seals that came with it "looked" really good and so I was sure that they would do the job, but they didn't

One thing that can cause an issue is the small bore pipe some taps have now, if the water supply is not at mains pressure the flow from the taps can be very poor.

don't forget PTFE tape on the threads, lots of it, in the right place.

Being a sparky and not a plumber , although i have moved and replaced the kitchen sink , and moved a radiator , i would say if the fittings are old , be prepared for if it can go wrong it will go wrong .

Whereas I go crashing in and 5 minutes later I have to ring a plumber 

[HarryHornby]

thought I had best report back:


Like you Mr Locksmith it took an age (0930 to 1430 Including 2 trips to Toolstation), I'm glad I don't charge myself an hourly rate! 


All sorted though, had to cut some pipes back a bit and then re-do a couple of the compression joints where I had bleeds I couldn't get rid of, but all there in the end.


Waste came out ok, put the new one in seating it on silicone sealent in the sink and also where the rubber washer sits under the sink.


Touch wood, jobs a gooden!

Did you use the basin sealer that I linked to
