Push Fit Plastic to Copper Pipe.

[conny]

I've been asked in work to find out the feasibility of using push fit plastic pipe, (15mm) to extend a copper pipe run, (15mm) by about 15 metres to serve a wall mounted tap which will feed a Karcher Pressure washer.
The copper run feeds the washer at the moment but they want to find out if its possible to re-locate it in another outdoor area before trying it and finding out it won't work.

Is this possible or would they be better/safer stipulating it should continue in 15mm copper?

Thanks in advance.

Someone will give you a better answer but I've read other articles about people extending copper with push fit plastic. If it's just a small run, I'm not really sure why people do it, solder rings are very easy to use but it can be done.

I also don't know about your pressure washer, but assuming it's just fed with mains water pressure you definably can do this, otherwise you would need to check the pressure rating of the equipment.

Plastic or copper, it doesn't really matter in this instance.
Just make sure, if you aare using isolator valves, that they are full bore ones.

Thanks lads, especially the reminder of the isol valves. Forgot about them.

Cheers.

remember a double check valve as well, the pros and cons of plastic/copper are well documented on here, on some installations i would use plastic depending on route etc, the advantage of plastic is you can buy a 15m or 25m coil therefore you have no joints to leak (i am a good plumber so making laek free joints on copper isnt a prob for me) the disadvantage of plastic on long runs is more clips are required (15mm copper needs a clip every 1.2m horizontally, dont know about plastic) so it is swings and roundabouts and what you prefer but there are no restrictions on what you want to fit

Thanks Kirk,
will jot it down in my notes he needs one of these as well.
