Hi Everyone

We had a bit of change on the original plan and haven`t had dedicate tap for the dishwasher.

I`m planning to get feeding after the isolation valve under the sink but struggling to find the right vale and connector to make it work.

Idea is to keep the isolation valve for the tap in case something goes wrong with it and have isolation valve for the DW.

Can anyone who has done this before help me

Many Thanks

1. When you say "after the isolation valve under the sink", presumably you mean before it in terms of the direction of water flow.
2. I'd suggest you:
2a. Isolate the water at the main stop cock.
2b. Get a compression washing machine tee valve. E.g. Screwfix 60723.
2c. Work out how much you need to cut out of the cold pipe to fit this valve. Likely to be the distance between two raised ridges on the straight part of the valve, but check carefully. Call this dimension "X".
2d. Cut the cold pipe about 50 mm below the existing tap isolation valve.
2e. Cut again X mm below this.
2f. insert the valve into the gap you have created and do up the compression fittings.
2g. Attach the dishwasher inlet hose to the tee part of the fitting.
2h. Turn the water on, and, barring leaks, you are good to go.
3. If your pipe is plastic rather than copper, you will need inserts to fit inside the cut ends of the plastic pipe. Inserts should be same make as pipe, and if pipe is Speedfit, the ones without the extra O rings.

Let`s recap to see if I understood properly

I cut copper pipe to the X dim. I compress fitting the exiting isolation valve and then with a short copper pipe I link together with compression the washing machine valve on top of it?

A picture of your pipework would enable us to advise you better.

Remove the isolation valve,fit a compression tee in its place, short length of copper then refit the isolation valve. The other branch of the tee fit a length of pipe and a wash Mac valve.

Basically - you need to cut and remove a section of pipe, to match the amount of space in the pipe taken up be the T outlet. The T outlet will probably have marks on in, which allow you to measure how long the piece to remove needs to be, but be wary of cutting too close to another fitting - you need space for the compression fittings and olives.

I have no idea when you started typing and frankly couldn't care less.
