Push into the bin.

If you need to use plastic pipe use good quality compression joints with the
olive wrapped in PTFE on the plastic pipe. A far better and cheaper joint
than pushfit. Also easily demountable.

All the pushfits I have worked with simply needed the collar to be
depressed to release. No need for a spanner. How easy is that? No need for
even a spanner.

Also PTFE tape is for use on taper threads, not on compression joints. It
is capable of making even Swagelok fittings leaky.

Only Speedfit, or the cloned Speedfit does that.

Most pushfit is difficult to demount. A compression joint on plastic pipe
is much superior to only relying on a very thin O ring - and cheaper. Even
with expensive plastic pipe cutters the odd nick can be left on the pipe end
and the O ring can be nipped. Then the grab rings can fail and the fitting
shoots out leaving a full open end. Some of the grab rings and corrode with
time if on the wet side of the O ring, again failing and catastrophic
failures. A compression joint is much more forgiving. No contest use
compression on plastic instead of pushfit fitting, which can take some force
to push on, especially in awkward locations.

Many in the trade have moved over to good quality compression joints when
using plastic pipes, completely disregarding and type of pushfit fitting..

Also PTFE tape is for use on taper threads, not on compression joints.

The plastic makers recommend the olive is wrapped with PTFE. I do not
recommend that an olive is wrapped with PTFE on a copper pipe, just a
"smear" of jointing paste.

Yes, strange. After fitting 2 loos, basins, bath and kitchen I ended up
fitting about 20 compression onto new and (and sometimes used) olives,
with no leaks ever. Maybe he stopped tightening when he heard it
creaking. I tighten to the creak, then another 1/8 turn. Stop.

I generally find that there's no need to tighten that much - after all
its easy enough to nip them up a bit if the weep, but there's not much
you can do if you over-tighten them and damage the olive.

Well, I apprenticed as a mechanic, so must of the tightening I do is by
feel. If it feels tight it is tight. It's hard to describe to someone
or put into words.

Me too. As an Agricultural mechanic, so working on compression fittings
on hydraulics etc for numerous years. It's not a new science for me,
just seems that the last batch of isolation valves I picked up seem to
have given no end of problems WRT leaking.

Use the best quality fitting like Conex, and a very slight smear of jointing
compound and no probs. Don't buy cheap crap.

I found that copper olives seem to seal better than brass.
I suspect it's because copper is softer than brass.

I've never had a problem with copper or brass olives on decent or

I'd say either the pipe or fittings were damaged in some way - assuming
you could get enough purchase to tighten them fully.

But I always put a few turns of PTFE round the olive before tightening
after cleaning the pipes to soldering standards.

Appalling senile missadvice. DO NOT use PTFE on the olive when using copper
pipe. Use a "smear" of jointing paste. "Always" use good quality
compression joints, like Conex and Kuterlite. Don't complain if you bought
el cheapo fittings and had problems. Wickes sell Conex fittings and at
decent prices too.

Think most know by now that your joints have a habit of leaking...

Use a "smear" of jointing paste.

Please explain in detail the actual difference in this application between
'jointing paste' - which could be anything - and PTFE tape?

Neither are strictly necessary anyway.

I always use end feed solder fittings. But then you need some skill to use
them. They're far cheaper and neater looking too. And never leak.

The PTFE trick was taught to me by a plumber who could do the most
beautiful pipe work you've ever seen. A true craftsman. Something you know
nothing about.

Paste works its way into any imperfections where the fitting meets the

And causes all sorts of heartache to people who look after Gas
Chromatography/Mass Spectrometry kit. PTFE tape also often carries
silicones (why exactly this is needed on a non-stick material defeats me)
which also give ghost peaks. It is entirely possible to achieve a good
seal with compression fittings with no adjuncts. Even the best seals leak
to an extent. If you can beat the detection range of a sniffer detector it
is as good as it gets. The mass Spectrometer will still pick up air gases
N/O/H2O on a really well sealed system. The molecules actually migrate
against the flow. The septum is normally the major culprit. Do feel free
to come back when you have som understanding.
