Plumbing in a sink & washing machine

[garak112]

As part of our new house refurb I need to relocate a sink and washing machine from one wall to another.

What is the easiest way to route the pipes - should I be using copper or plastic (which I assume would be quicker)?

I'm a traditionalist, copper & soldered fittings ideally.

Known peeps to use plastic & it's come apart, due to they not fully seating the pipe in the fitting, & many other reasons, & ended up with flooding the kitchen.

Copper just because you'll be running it in an area of high impact or somewhere you won't want to be pulling up again.

Plus you really should do the last bit in copper anyway.

Waste in plastic.

use speedfit fittings,so easy

Use Solvent weld wasting fittings, I have no faith in push fit plastic waste fittings, after a slight mishap with them, not me, but my neighbour.

Copper plus my new favourite: cuprofit. Rock solid and as easy as connecting lego.

Those cuprofit are very good, got given some by a rep to try.

What size pipe do I need to buy and how far apart do I need to attach it to the wall?

 

[Nightglow]

15mm copper pipe clips spacing usually 1000mm horizontal, but I prefer slightly if behind a washing machine, & 1200-1800mm vertical.

Waste pipe 40mm plastic.

As to washing traps either this if it's not close to a sink.

Or this, replaces existing sink trap.

Don't forget about your waste pipes too, they will probably need to be plastic.

Cheers guys thats very helpful.

I noticed this evening that there are no radiators upstairs (how did I miss that?), looks like a fairly simple job to put more in using speedfit.

Haven't got a choice really as my gf is always cold.

Yeah, how did you?

In my defence the wallpaper is so awful in the upstairs bedrooms that I couldn't stand to stay in the rooms for very long (plus when we looked there was furniture everywhere).
