Answer 1

I did the same thing about 2 years ago. You need a 'y' shaped waste pipe and the same with the cold feed. you can do it yourself but go into wicks or b and q to get the part. I would be a little cheeky too, most men that are standing around that area know what they are talking about (not the staff!!) so ask them before buying.

Answer 2

We tried to do this a couple of years ago but could not get the right connection - a double waste spigot. Also we were told that if we used this we wouldn't be able to use the dishwasher and washing machine at the same time. In the end we got a self tapping screw to attach to the cold water supply pipe and put a separate waste pipe through the wall into the drain. It was so easy, my husband was able to do it!! Now we can use both appliances at the same time.

First off, you need a hot water feed line for your dishwasher, not cold water

Secondly, if you have a garbage disposal installed on your sink you can connect the dishwasher drain hose to the side port on the garbage disposal. That's what that little port is for anyway. If you do have a garbage disposal and hook the dishwasher hose to it then make sure you take a hammer and screw driver and knock out the little plastic plug that's inside the garbage disposal port before hooking up the hose to it, if you don't you'll flood your kitchen.

If you don't have a garbage disposal on your sink, then you're going to have to replace a piece of your sink's drain piping with a wye (Y) tailpiece. The tailpiece has a small branch that comes off it to where you can connect the dishwasher drain hose.

Regardless of which way you hook up the drainage and water lines, make sure you test out the work you did by running the dishwasher and keeping an eye on it. I can't tell you the number of times i've seen people hook up stuff like this and not test it and then when they go to use the dishwasher it floods the kitchen..... usually when people are sleeping at night. Test your work.

Dishwashers require 120F hot water, anything less will not melt the soap. Also if you have a water softener it is only connected to the hot water. Get a plumber or ask at a local dishwasher sales company for the name of a professional dishwasher installer believe it or not there is such a job. You will be very unhappy with the cleaning results without a correct installation. If you must do it yourself consult the installation guide that came with the machine. If you do not have a manual and an installation guide, you can contact the manufacturer and have them send you one or probably find it on line. "Sears.com" sells manuals and parts online. Good luck.

Answer 5

Most dishwashers require hot water connection. If for nothing else, to save energy since the DW heater would need to heat cold water to 140 degrees. The drain is connected to the sink drain with a dishwasher tee. You can purchase a double outlet water supply tee to replace the shut-off valve you have now.

Answer 6

You need a tailpiece with a dishwasher inlet installed on the sink drain.
Are you sure it's a cold water feed? Most dishwashers are hot water feed.
You need to tap into the water supply for the sink somewhere under the sink where theres enough room to install an additional valve.
Then you need to connect that valve via copper tubing.
If you're that unsure, or it sound like alot of work, call a professional.
Good luck!

Answer 7

As long as you know where your mains supply is turned off you can do it yourself and t off from the one cold feed, and t into the waste pipe.


Oh my days, the guys above are handy round the house... Most dishwashers are hot feed??? WTF? Oh yeah most houses have a hot supply of water just for dishwashers, lol the majority are cold fed. What on earth have they been reading? Whats all the jazz about copper piping and valves are we going back in time or something? Its all PVC these days. lol, Jokers stick to your day jobs chaps.

End of the day check the speks on your machine, but the one I've just fitted doesn't require the central heating to be on in order to work!!! Or did I miss the mains supplied hot water, lol. Sorry I am being fickle, you do get hot feeds, but you will see with the tubing supplyed a red hose, not copper, red PVC, but it entirely depends on your machine.

Either way it is exactly the same operation, if you have been supplied with the red warm feed pipe then you t off the warm feed to your sink. What do people think you need to install a seperate feed???

Answer 8

we run into this on a daily basis , ok so which you're taking a small length of copper pipe perhaps 4 inches and clamp that to the tip of the present dishwasher drain hose( many times one million/2" or 3/4"pipe ) after which connect yet another length of hose ( bought at domicile depot , Lowe's or any stable ironmongery save ) clamp that on after which clamp it to the disposal . in case you employ stable high quality hose and clamps ( chrome steel in ordinary terms ) you will have years of un interrupted carrier .particular it is legal and as much as code .

Answer 9

connect to the water supply with a Y piece, and try to find Y piece for waste if you cant find Y piece for waste get a waste saddle joiner for this basically you attach it to existing waste and it makes it own hole in the pipe when you screw connection together

Answer 10

You need a plumber. Connexcting to the drain is not too much of a problem (although I wouldn't do it!) but you need a plumber in to set up a cold water pipe to your dishwasher.
