Copper Pushfit - Not for use with gas

[Andy Hall]

Only if you don't use them properly and don't follow the instructions. Ears gone red yet?

Many pros don't fit condensing boilers and you criticise them.

That really is a bodge.

[Andy Hall]

It's OK. You said that you had an enquiring mind..... :-)

[Doctor Drivel]

Matt, read on....

The point is pushfit fittings. You lack focus.

Matt, it is clear you are a rank amateur and don't know anything about pipework. The plastic pipe makers tell you how to do it in their manuals.

[Chris Cowley]

But there are some places into which even my nosey nature would rather not enquire. :)

[Tony Bryer]

In my old BCO patch much of inter-war New Malden was built by Wates who were one of the first adopters of Marley tiles. Most of those roofs have decades of life left in them - the tiles may have lost their colour but are otherwise sound. Down the road in Berrylands, Surbiton, most of the clay tiles have delaminated and have had to be replaced.

[Dave Plowman (News)]

Seems dribble is still hanging about with the same dodgy 'pros' who told him it was ok to cut plastic pipe for a fitting with a hacksaw.

Or perhaps they were just winding him up before telling him to get back to the sales counter.

[Dave Plowman (News)]

I'm sure it depends on quality.

I had the rear addition on this place re-roofed from clay to Marley - due to physical damage to some of the clay ones.

And on changing the rear addition sloping roof to a roof terrace some 15 years later was surprised to find just how badly some of the concrete tiles had deteriorated. Frost appeared to have damaged the surface.

[Andy Hall]

How would you know? You don't read the manuals - or if you do, certainly don't do what they say....

[Doctor Drivel]

Matt, I read the manuals. Boy are you dumb.

[Doctor Drivel]

** snip drivel from Matt **

** snip babble from a senile person **

His taps still dribble as he fitted high pressure taps on a low pressure system. Yes senile people do these sort of things.

[Andy Hall]

You may have read, but clearly you didn't understand or you chose to ignore.

[Doctor Drivel]

Matt, I did read and ...boy are you dumb.

[Ed Sirett]

1) Not approved, so even if they were the most gas tight fitting in the world they simply would not be permitted. 2) Have plastic parts whose fire resistance is questionable. 3) The firmness of the connection is enhanced by the internal pressure. Clearly pressures measured in bar have a bigger effect than those in mbar.

[Ed Sirett]

.... underground.

[Andy Hall]

.. and still screwed it up....

..boy are you dumb.

[Doctor Drivel]

Matt, I never screwed up reading them at all. boy are you dumb.

[Andy Hall]

Possibly not. It's the understanding and execution where you came unstuck......

boy are you dumb.

[Doctor Drivel]

Matt, that is better. This is encouraging. A sign of improvements.

[Lobster]

What was the actual mode of failure, and how long had it lasted?

[David WE Roberts]

It must depend on all sorts of things.

My 1930s house has clay tiles - still the originals as far as I can tell. My 1950s house has concrete tiles - still the originals as far as I can tell. My 1890s house had slate - still in fine condition now when I pass it every year or so.

For long life slate has my vote - it was around a while before being put on the roof - but I guess it is a tad expensive these days.

We are now well off topic but isn't it much more civilised than most of the rest of the thread?

Cheers
