Adding a cold water feed for dishwasher

[totallytech]

Hi Guys,

I'm looking at running a cold water feed from the kitchen to the utility room. Its about 5m away from the washing machine feed so I was thinking of fitting a 'T Junction' connection of 15mm speedfit to the existing speedfit pipework. From the t Junction I'm planing on running down the wall, along the skirting board and through the wall, then using an elbow round the corner, to the dishwasher.

I think I'm going to need 5.5m pipe, dishwasher tap, 2 x equal elbow, an equal T Junction.

Do you think 15mm is enough or should I be looking at 22mm? Will a run of 5.5m with 2 bends in be acceptable?

on a cold mains water pipe - that`ll all be fine in 15mm

It will be fine esp if mains water.

Fab thank you, yeah its mains feed cold only. I'm assuming the washing machine tap is the same as a dishwasher tap lol.

I've just looked on a well known online auction site and found 15mm speedfit.

1 x 5m pipe @ 6.99
2 x elbow @ 1.14
1 x t junc @ 1.38
1 wash tap @ 3.50
24 x open clip @ 0.99

All in with postage is £18.58 - Seems very cheap to me lol

Could be a nice cheap installation to help out the missus!

That stuff is cheap - and speedfit is good - but you must use inserts on the plastic joints ! copper into s/fit is fine , but must be cut with a pipeslice , not a hacksaw .

Ah ok, so I'll need pipe inserts too. Daft question, Do I use a pipe insert on the connection as well as the pipe? i.e. when I cut my existing pipework, and add a t junction, I'll need 3 pipe inserts or 6? 3 would be just in the pipe connecting to the t junction, 6 would be in both the pipe and the t junction

I'm guessing its just the pipe side of the connection- also just noticed I'll need 3 elbows, and it'll be 10 pipe inserts?

splice t junction in to existing pipe (3 pipe inserts)
down wall to first elbow (1 pipe insert)
along skirting board to next elbow (2 pipe insert)
along skirting board to next elbow (2 pipe insert)
up wall to dishwasher tap (2 pipe insert)

And push-fit barrier pipe should be cut with a proper cutter:
