Hi all,
I want to install a dishwasher, beside an existing washing machine in a kitchen. What I want to know is ,
-- is it alright to connect up a 'y' connection to the cold water supply? And if so will this effect the water pressure and the appliances if I have the two of them on together?
--Underneath the sink there is a waste pipe in the shape of a 'Y'. One side has a blank and another feeds the waste pipe coming from the washing machine the other obviously goes to the drain. My question is ,.. Can I connect up the waste from the new dishwasher to the blank side (taking into concideration that I remove the blank of course)
Thank you:rolleyes:

I was always told never to connect an appliance to a kitchen sink waste,the reason being that if the sink was ever blocked ,your kitchen would be flooded.

But wastes do come with connections for appliances and in apartments etc ,you have to do what you have to do.

In regards to your water ,is it a direct feed from the tank? ,off the mains??

This won't be a problem. Even if both are on together it will just take them a little longer to fill. Each machine has sensors and won't allow the program to advance until the water reaches a predefined level.

Again, I dont see any problem with doing this. You can get a fitting from a plumbers suppliers that you can push your rubber outlet hose onto rather than just "hanging" from the waste pipe. The advantage is no potential for leaks if there is a degree of blockage and further, no backdraughts allowing foul air back into your room.

Can I ask how much a plumber would generally charge for plumbing/fitting a dishwasher and washing maching.

I think the last time I put a Washing machine in,we charged about 120 euro.
That was for a new waste running to the drain outside ,fittings etc.
For a feed aswell within 6ft, it would probably be another 35 euro on top of that.

My first plumber flowed both the wastes through the same pipe... second plumber said that was not a good thing to do and put in a second waste, one for the sink, one for appliances. The logic was as Brian described.
