How do I replace my bathroom sink?

if you have a combi boiler that is no tanks then just have to turn off mains cold water supply and open upstaires taps and downstairs taps to drain any remaining water but if you have tanks in the house then you will have to turn of cold water mains tap and then drain hot and cold water tanks by opening hot and cold taps on bath untill tank is empty at which point taps will stop running then you will know tanks empty safe to disconnect sink and fit new one undo nut under sink connected to taps undo waste behind pedistal undo screw if screwed to wall remove sink and replace with new one reconect wast will have to replace 1/2 fiber washer in the nuts taken off taps once replaced refit nut back on to taps turn mains cold water back on allow to fill tanks shut all taps and check for leaks hopefully all ok if any leaks need to redrain down hope that enough info

if you are not sure what system you have why give yourself a head ache just turn mains stop cock off turn kitchen cold tap on should not run if mains closed then turn cold tap on in bathroom if stopped turn on hot if stopped get stuck in first fitting ball a fix valves to basin pipework only a couple of quid and next time so easy to isolate
however when you open cold bath tap water does not stop leave running and have your tea and bicys will stop after main tank ,if you have one is drained down when stoped turn on hot tap and wait to stop when it does crack on fitting valves to basin pipework
reason cold tap first dont want to waste hot water however if job planned and no hot water in cylinder both taps bath taps can be turned on together
by carring out the above no matter what system you have then water suoolp tp basin is cut
and ps make sure you keep kitchen tap open as if main stop cock letting by slightly water will discharge through this tap and pps when you open up stop cocks and valves firstly just crack open and check your new joints are sound also then open up fully then close half a turn this way when you want to close and open them in 5 years time they should still operate ok if you open them up fully they get very very very stuck after a few months

Hi if the house you are in is quite modern there should be 2 shut off valves under the sink one on the hot water pipe and one on the cold water pipe they are silver in colour. and a screw slot in the side to turn off the water (half a turn only)if you do not have these THEN you must turn off the cold water at the stop tap there should be one in the house.depending on what system you have in your house this action can also cut off the hot water as well check this by turning on the hot tap if hot water has stopped ( it will run for quite a while As it drains out of the pipe work ) if it does not stop or slow down after say 5 mins see if you can find the stop cock for the hot water and turn that off . if you have a combi boiler shutting off the cold supply should do the trick Hope this helps , let me know jim

Hi Mark, no, I haven't a clue, I reckon that I'll be able to disconnect the sink alright but it's the water situation that's worrying me, I don't know where or how to turn it off and whether I have to empty the hot water tank or not, thank you for taking an interest, Ali
