Temporary plumbing

[Jupiter01]

I am planning to replace a kitchen and as part of that, gut the whole room out.

I want to temporarily run the sink, washing machine and dishwasher from the nearby living room. I will need to extend plumbing to this point which is around 3 metres away from the current location. This will provide space in the kitchen to gut out and fit the new kitchen, whilst running these for as long as I can - whilst the work is underway.

I plan to use some hep20 pipe for the water as the pipe in the kitchen will be flexible enough to move out of the way when I am doing floor or walls, etc.

Is there a similarly flexible solution for the waste pipe? I can’t clip to the wall or anything like that as I will need to tile, etc.

Also, if I run it at low level, it can run under the new cabinets until the last moment - I could do with some advice around how this should be plumbed too please? As I also need to think about disconnecting it at some point.

Sorry if I’m waffling but hope you get the gist of what I am trying to achieve. I would welcome your thoughts on this.

Thanks in advance.

I guess, hep20 will be appropriate, as these arrangements will be temporary.

Hep20 is fine for the water feed but unsure on how I can have a flexible waste pipe. Would appreciate any thoughts.

You could do some sort of lash-up with trench ducting I suppose. Or just use pushfit and live without the appliances and sink when you're tiling

The kitchen refit will run for a couple of weeks as I will be working in the evenings and weekends...
I will need these things to be operational at their new site during this time but don't want the pipe work to become a nuisance as I gut out and then start to do job in the kitchen. I didn't know if some flexible version of the waste pipe existed. That would have been ideal

For a flexible waste pipe, use a flexible waste pipe. You can extend the waste hose , with an air admittance to stop it siphoning. Ask your plumber's merchant. B & Q probably do them too. Edit - see link. Rigid waste is cheap enough that you can use a couple of lengths somewhere temporary then scrap them if that's feasible.
You can get 2.5m WM supply hoses, daisy chained witha 3/4" nipple (M - M), if you need.
