Olives and copper pipe

[johnofgwent]

Never really thought of that.

I am going to find some sort of meter to measure the actual water pressure.

I reckon that all would be well were the pipe work ok, but the last lot of stuff I got from B&Q was bent all ways to Sunday. Apparently they use plastic olives in Australia but I am blowed if I can find any in the UK, so I imagine that I will fall back on PTFE.

I am so bloody sick of this business. I have spent two weeks putting in a couple of metres of pipe and a stop cock, and the screams you can hear are
from me pissing razor blades.

I really really want to go to my allotment and dribble bollocks with the rest of the geriatrics, but I can because of this poxy plumbing.

I blame everyone else

OFWAT require the mains cold water pressure to be above 0.7 atmospheres approximately 21feet of static water pressure at all times.

Plumbing in a high rise is a challenge.

Can't say I understand your problem. 

I helped out on a couple of properties with plumbing jobs. Cleaning all surfaces with wire wool and tightening well, but not too much, worked on prestex type joints — though we only used them where Yorkshire solder fittings couldn't be used...

The answer is the olive is a softer metal and the compression of making the connection distorts it to make a seal sufficiently watertight to withstand mains pressure.

Watching them fail as higher pressures are imposed is ... Fun.

When paid to test the solar energy rigs on top of the student union I was soldering joints to withstand hydraulic pressures of whatever the hell 10 atmospheres was

The idea is that you screw the pipe into the fitting and in doing so, the olive makes the fitting water tight.

It seems bollocks to me. How can a chunk of metal seal a pipe?

But it does.

All my life I have slapped a dollop of Bosswhite and some hair on the thread and whatever happens, there is a leak. Then I start again. Clean the thread, put in a new olive and the whole thing is as sweet as a nut. No leaks.

I quite enjoy plumbing, but I don't understand it.

I think that's when people forget to put the insert in.

Not something professionals should do,but then seen some shockers by so called trades.

Yes but
They are but are also known to suddenly give way,and flood if you are not taking care.

You sound like my late husband except he didn't understand it or stop the leaks! Push-fit is the way to go now though.

Yes but 

I was just going to say, use Hep2O fittings, they're so easy.

True Toots, but as said, no one is asking my opinion.
