Plastic or copper? which is best?

[rpm]

Another reason it will keep cropping up is as wonderful and quick plastic is, people are realising how long lasting, rigid and quality copper is.

Let's see how the quality of copper is after we crash out of the EU

Doesn’t most of the copper come from China? Surely we could trade with them outside the EU?

 

[ShaunCorbs]

Copper but starting to use a bit more mlcp these days

Easier to snake around the sparkys

Any friends of the US is no friend of China at the moment.

True. But I honestly cannot see them turning us down.

Out of curiosity, is that pipe suitable for standard hep/JG push fit fittings? It could be quite easy to mistake it for standard pushfit if you only took a small section of board up and only saw the pipe, not the fittings.

No it’s not

Also you won’t get pushfit fittings to fit

16,20 and 25mm dia

I see. Is it semi rigid pipe? Looking at the pic, your pipe tails don't seem to be curling over as standard PF would. I haven't came across the stuff before.

 

[ShaunCorbs]

The easiest way I can discribe it it’s like soft copper can bend by hand etc

How does it compare price wise to copper?

Cheaper tube wise

Fitting wise around the same ball park as press

Nope, people realised that, as soon as plastic made its debut.

Does it require require stupidly expensive tools, and is it suitable for gas?

Manual tools arnt that expensive powered tools arnt that bad around 1.2k or 1.4 with both u and m profiles

And not in the uk yet

Not that bad at 1.2k? . You must be one of those rich plumbers I keep hearing about

I need to do that, had a lot of mine for years now.

The critters bite into plastic?

City slicker eh?

 

[Burger]

Copper for me, can't do gas in plastic.

Copper....obvs.

 

[Staffy85]

hate barrier pipe {jg/hep/polypipe etc etc} with an absolute passion! , the only pushfit system that i like is pegler yorkshire's tectite, its a MLCP pipe so it can be bent by hand and stays in that position and doesnt expand anywhere near as much in length as plastic does , comes in 15/22 and uses double sealed liners with stainless 316 fittings..

COPPER

 

[Pickwickpick]

Copper here too, not only is it a superior material for this usage, I also find soldering ever so therapeutic (people normally look at me like I'm a freak when I say this). Its ever so satisfying looking at shiny, neatly soldered, tidy new pipework!

 

[Scott_D]

Is copper too good?
It lasts so long nobody gets a repipe just a new boiler onto an ancient system

Buteline offer a 25 year warranty on the plastic pipework. It has no O-rings and is press fitted.
Their rep said they will be upping this to 50 years soon.

Gerberit offer a 1 year guarantee on their Mapress copper press fittings.

How long a guarantee do you offer on your hand soldered copper pipes?

If you want to offer a manufacturers backed warranty on your installation, like you do with boilers, the answer seems simple.

Install plastic

[lights fuse and retreats to a safe distance]

I’m DIY of 40 yrs experience. I recently did a re plumb job for daughter. By pass leaking underfloor pipe (2 litres a minute). The job took far more time than myself and brother-in-law estimated. Like 6 times as long. Very awkward access, under bedroom floors and in tiny loft etc. Waving a blow torch in restricted space not easy or quick. Had it been easy to get at we could have done it in a fraction of the time. Plastic would have made it much easier ... long pipe runs, gentle curves over rafters.

My costing for MATERIALS, Screwfix prices. Copper and plastic pipe .. not much in it. Copper and plastic joints ... copper wins Easily. Fitting. Plastic is so quick, less joints. Now I prefer copper but I had to use one plastic bend in an inaccessible place on copper pipe. Amazingly easy. See photo at bottom.

My experience of copper is that is sometimes doesn’t last as long as you anticipate. I had two pin hole leaks in 30 years in copper cold water feed to trad boiler, cast iron boiler , not combi, feed was from expansion tank in loft and flow down pipe must have been virtually non existent ... just water expansion. But might have been bad pipe?

So I would say a proper job with longest life would be copper. fittings look better. I suspect quotes for a plastic system would be cheaper as there must be less labour. In new house builds what do they use? In top end house builds what would be specified, reguardless of cost?

At the end is photo op plastic fitting I added in inaccessible place to join 2 copper pipes. I had to cut away wood to give space to fit it. I haven’t forgot to insert the other pipe! Oh yes. Some plumbers don’t clean flux off copper ... and it corrodes. I believe British Gas had problems with corroding copper pipes and did a lot of research on what fluxes not to use.

Then was a plumber friend who had copper oil line, passing thru wall, corroded through in weeks. He had no idea why.

So Copper can give a Proper job, more expensive, can be longer lasting, rodent proof. Visually less intrusive and you can see some beautiful curves from skilled pipe benders. Polishes up nicely ... I once worked as a loo attendant after leaving school, and during Uni hols. Polished the copper urinal pipes every day.

Plastic job, likely to cost less as less labour intensive and less skill needed.
