You want to replace an existing kitchen sink in flat pack form which includes a cabinet, stainless steel bowl with a drainer on each side, two hole mixer tap and all the parts for the U bend trap. Brockley Plumbers supply and fit various types of units.

Method.
1). Make sure that you are prepared for a full days work by stocking up on food and drink to keep you going. Isolate the mains water supply. Use a hacksaw to cut away the old sink from its supply and waste pipes being copper for hot and cold and plastic for waste that runs through the wall and away into the drain. If the waste pipe is over 5 years old then it should be replaced.

2). Assemble the cabinet in line with the instructions and clamp the bowl and drainers in place.

3). While the back of the cabinet is accessible position the mixer tap in the holes provided and ensure that it is centered and then fit the back nuts, top-hat washers on the two threaded tails and tighten firmly.

4). Fit the flexible integral valve connector to each of the two tap tails-one for hot and other for cold. These are good options for two reasons, they make the process of joining the sink to the water supply pipes easier and allow for servicing of the taps without isolating the whole system.

5). Fit the U bend to the waste outlet with the flexible pipe banjo overflow running upwards to the overflow hole.

6). Once this is done, move the whole cabinet complete with the sink unit over to its final position and decide whether or not to extend or replace or even reshape the existing hot and cold supplies and waste pipe.

7). Remove the sink unit and fit the waste pipe, extending the hot and cold supplies as required. Move the cabinet into place against the wall and link up all the pipework. Clean all around the joints and dry with tissue. Turn the water back on and check for leaks. If you are not confident call a professional like a Brockley Plumber .
