It seems crazy to me to save an hours work and fit something that may
flood the place 20 years later. I wouldn't touch it myself.
The future can seem a long way off, but it comes anyway. Imagine if
you'd fitted pushfit in 1972, thinking 'millennium? hah' and now got
flooded from it. Not for me thanks.
Proper pipework fittings are
a) known to work well from experience
b) have a very long life
c) are a bit more work, but not much.
Some things are no big if they fail, but plumbing has consequences out
of all proportion to its cost.

I'd be dubious about the longevity of the o-ring seal.
Normally, I see up to perhaps ~20 years life of those
in similar circumstances.
d) need [more] skilled workforce to correctly assemble.
This is the big one -- plumbers have become impossible to get
hold of. (A friend having an extension built has been told by
the builder that he will not be able to get a plumber to do
the plumbine parts, due to extremely short supply.) A less
skilled workforce can probably do a more reliable pushfit
installation than they could a soldered copper one.
Personally, as my DIY time is free and I can do soldered
copper fittings without any problems, that is what I use.
However, I can see a market for pushfit.

I use pushfit because I'm crap at soldering and haven't got the time
and resource to practice until I'm any good - most often a job needs
to be done NOW, like today when I unscrewed a floorboard and
discovered that a year ago I'd managed to screw into the cold water
pipe that feeds the bath :)
As an aside I was in the local plumbers merchants for another reason
(bloody 1 1/4" waste on the bath innit) and noticed ALL the current
plumbing products, even Kuterlite and Yorkshire, were guaranteed for
25 years. Doesn't that drop us into a swings/roundabouts scenario?

Yup, tho compression would be as easy as pushfit, skill wise. A
compressed metal ring should last way better than a rubber washer.
Me too, but once you understand the ins and outs of it I still can't
see a reason to choose it. I suspect it may become one of those no-nos
like aluminium wiring. They seemed like a good idea at the time, but
with a bit more thought we could have avoided them. I can see plumbers
in 30 years saying 'pushfit? well you'll need that replumbed for your
insurance to be valid'
Having said that, pushfit used for external downpipes shouldn't matter
too much if they leak.
I tend to agree. What the makers seem to be saying is it has roughly
the same lifespan as elctrical wiring (give or take a decade or 2).
Thus in future having a house re-plumbed for insurance purposes will be
as standard a proceeedure as re-wireing is now.
I think i'll carry on doing what I'm doing now - use pushfit when in a
hurry on easily accessable areas and copper when doing a proper job.
Thanks to everybody for their contributions.
If Mr or Ms Hep can provide
a) independant data that shows pushfit to be as reliable as solder,
solvent and compression
b) a 50 year guarantee that covers damage to the house and will still
be genuinely claimable on in 50 years time
then I might well be convinced.
Has anyone seen a guarantee for Bosswhite and Hemp or CAF joints? I think
there is just as much chance if not more that EPDM seals will be around and
giving good service for longer than Hemp or other fibres
Pushfit has been in use for 25yrs, probably longer in fact, how long do
you want to wait before it proves itself? The only plumbing damage I've
had was caused by pinpricks in copper pipe, probably thin imported
stuff, and leaking compression joints, do you want to hang on while I
look for the guarantee that covered them? Do you know of any plumbing
related materials and devices i.e boilers, radiators, appliances etc.,
that have a guarantee that covers damage to the house if they fail?

I didn't know that.
I dont know. How long does soldered copper piping last? How long do
compression fittings last? How long does pushfit last? I dont have any
definitive answers to those qs, but I would expect [on a gut level
only] that synthetic rubber seals are unlikely to last as well as
solder or copper olives. I'd be perfectly happy to be proved wrong on
No, and thats just why I am still at this point wary of installing
something that I expect to fail some day, with, in this case, possibly
rather damaging consequences.
If someone actually has hard data I'd love to see it. After all, its
perfectly possible that pushfit could turn out to be more reliable
than the others. Until I have more info tho, I'd prefer to avoid it.
