connecting dishwasher

psd99 · 16 Nov 2017 at 10:46

just a sanity check here

I was trying to upload a picture but did not work

I got a setup where the water cold is connecting to a 15mm tee.

3 way device thing -

- mains water
- kitchen tap
- washing machine

I'm looking to get a dishwasher it's a new one never had one before
what do i need to connect it to the cold water supply?

I was thinking:

- 15mm pipe
- 4 way tee
- isolation valve
- one of those silver flexible hoses

am i on the right track? Can't seem to find the 4 way tee
still looking though.

That would make it an X

leave the existing T in place.

Install another above it in place of the tap isolator.

Reattach the tap isolator to the top of the new T.

Connect the new pipework and isolator valve for the dishwasher to the other outlet on the new T.

Don't do anything until you've seen the dishwasher connector. They often have anti-flood devices on them that are quite large and may need to be installed in a specific orientation.

yes def not doing anything until I see the dishwasher

this is more long wounded that I thought

any chance u could link me the parts I need?

also with your method - that means that anytime I'm using the sink and the dishwasher the water to the sink will be reduced

that's the normal right? no way around it by the looks of it damn
I might put this on hold now was hoping to get something in the black friday sale.

psd99 · 16 Nov 2017 at 11:12

so what parts do I need?

please confirm if possible.

bremen1874 · 16 Nov 2017 at 11:13

Actually you could probably get away with a washing machine tee valve and a short length of 15mm pipe.

Install the valve in place of the existing tap isolator.

Reattach the tap isolator above using a short length of pipe.

btw totally unrelated there is another pipe on the right the plumber said it is for softer I couldn't understand what that meant
what is it and what do i need it for?

bremen1874 · 16 Nov 2017 at 11:15

Do you have a water softener?

ok so the dishwasher uses the same connector as a washing machine?

will look later on this thanks.

well the pipe is there but no I'm not even sure if I will ever need this.

psd99 · 16 Nov 2017 at 11:21

I think I have these parts in the garage

but the 15mm pipe might be difficult to find in a small piece mmmm

bremen1874 · 16 Nov 2017 at 11:21

Can't tell from the picture.

Depending on the placement you may be able to replace the existing washing machine outlet with a twin version:-

or even a simple Y connector:-

At the worst you'd need to buy a 3m length for about £7.

so there are many options

can I use the first one in place of the cold water tap to the sink? the washing machine connector is on the other side of kitchen almost

it is the cold water connector to the kitchen tap you see in the picture on the LHS

The isolator for the cold tap has a different size outlet (smaller).

mm in that case your original option will be better
could u help me with the parts please?

psd99 · 16 Nov 2017 at 12:34

so just this part then above existing isolation valve to the kitchen tap

https://www.screwfix.com/p/washing-machine-valve-tee-15mm-x-15mm-x/60723

+ 15mm pipe

bremen1874 · 16 Nov 2017 at 14:22

That'll work.

You could also use the push fit version if you prefer that sort of fitting
