15 mm water pipes - which make/model?

[Possom]

On another thread it was stated that solvent weld pipes are the way to go, with regards to 40 mm waste pipes, instead of push fit. I was therefore wondering what your thoughts were with respect to 15 mm pipes required to bring water to a bathroom basin, toilet, bath, and over-bath shower.

I noticed five varieties for sale (links below), with the last three being push-fit. Thanks!

copper for me.

Lead (off a roll on my handcart)for me....





Seriously, copper's proper, and plastic's fantastic when in a tight fix, but it is fuggly.

 

[Possom]

but it is fuggly.

I'm not sure i'm familiar with the word fuggly.

I'm not sure i'm familiar with the word fuggly.

The swear word f**k followed by ugly gives fuggly. Meaning not pretty, beaten with the ugly stick.

 

[Possom]

What if the piping won't be visible as it would be within a partition plasterboard faced wall, therefore it doesn't matter that the piping is fuggly.

Maybe still best to go copper, as maybe the plastic coiled piping could develop issues over time which the trad copper wouldn't.

 

[Possom]

I've just thought of a couple of other questions:

a) If installing *vertical* 15mm copper piping within a partition wall from ceiling to floor, I presume clips should be attached to attach it to the timber frame as per plastic piping? If so, are regular plastic clips used as for plastic piping, or special clips for copper piping?

b) If installing 15 mm copper piping throughout the bathroom, and this is then brought immediately outside the bathroom to be connected up to the rest of the household plumbing system (which is 15mm *plastic* piping), how is the copper connected to the plastic?

Thanks!

Standard stand off pipe clips are used for both copper and plastic. Ideally you would use a push fit coupler to connect the copper to the main plastic pipework.

As long as all the old copper pipe is metric (i.e post 1974), and cleaned back to bare metal, AND is perfectly circular AND had no sharp edges on the end (a pipe slice is easiest to use) to damage the 'o'ring seals, then if needed plastic push-fit fiitings can be used.
Myself and other pro's would not use push fit or compression fittings in an inaccessable position, but use soldered joints.
Hope this helps, but, if plumbing&heating was easy everyone would be doing it

Any of those plastic pipes can be used with push fit connectors as long as the appropriate insert is used.

But I would always want to use soldered copper!

The copper would be brand new, as I would have it installed in the re-furbed bathroom instead of leaving the old plastic piping currently there.

That is, due to the fact that it's copper piping that has been suggested in this thread as being the better option.

Myself and other pro's would not use push fit or compression fittings in an inaccessable position, but use soldered joints.

Presumably though you can't use soldered joints where a copper pipe connects directly to a plastic pipe.

 

[Agile]

No, only compression or push fit.

Of course, soldered is always the best option Not for a copper to plastic tho

DIY'ers though who may not have the skills nor the equipment, then pushfit would be the next best option.

 

[Possom]

When I think of push-fit fittings I immediately think of plastic fittings.

I've just learned that there are copper push-fit fittings also (Tectite Sprint):

copper or plastic push fits work on both copper and plastic. I think the copper push fits are for when they're on show.... you pay a premium for them.
