The plumber who installed our power shower in 1997 used plastic pipe teed off
the stainless steel 15 mm pipes to the hot and cold basin taps. He omitted to
fit isolation valves so had to do a quick bodge yesterday (see Mira Shower post)
and bought a couple of standard Speedfit valves from B&Q.
I have not used plastic before so an a bit unsure about mixing pipe and
fittings.

The pipe has the following text (some illegible):-
HBP.UK illegible Part 2:1990:Class H PB H&C services & central heating 12 bar
20C 7 bar 82c 15 x 2.0mm 0722242KF02.
May be some mis-reading there.

Am I right that this is an early HEP2O type of barrier pipe?
And is there going to be a problem using Speedfit valves with it - they are
still dry after 12 hours.

I only have access to (retail) mail/internet order or
B&Q/Screwfix/Wickes/Homebase.

Probably BS 7291: Pt. 2: 1990 Polybutylene pipes and associated
fittings.
Don't know what HBP is. Hepworth Brothers Plumbing? Wavin own it now.

Probably polybutylene, HEP20 was the major brand but there were other
manufacturers.

Probably not, but the makers instructions usually recommend against it
because they won't guarantee another maker's fittings. I'd crack on
with it.

Are you sure it's stainless pipe, not chrome. IIRC there are problems
with push fit gripping stainless &/or chrome. You'd best look up the
installation instructions.

Hepworth Building Products Limited, apparently. It probably is HEP2O.

Yes, can't be connected with push-fit to chrome or stainless, you have
to use compression fittings. If he has then that's all OK.

in their usual "thinking of us consumers first, not their profits"
type way.....

bet you it'll be fine - just ensure you get pipe stiffeners in where
the pushfit gear is installed....

Last time I used Hep2O was about 2000 and there were 2 types: barrier for
CH and non-barrier for water supplies.
This might have changed by now - looks as if all Speedfit is barrier.

Thanks for the replies - I have replied below

I bought Speedfit inserts but initially was unable to fit them - have now tried
a smear of silicone grease and got them into the pipe with a bit of pushing.
(For the record I also bought a pipe-cutter :-)

The original house pipework /is/ all stainless steel - right pig to work with.

The plumber used brass T to come off the original pipes - not sure if the branch
is ordinary compression - it looks normal.

The plastic pipe had a couple of in-line couplers under the bath - these are
also marked HBP. Only reference I found on the HEP2O site was that using these
could be a cause of seepage.
http://www.hep2o.co.uk/v2Ofaults1.htm
2. Problem: Joint weeps
"e. Components from an old Hep2O® or Acorn® fitting may have been used when
ressembling a Hep2O® fitting. The cap, metal grab ring, 'O' ring and spacer
washer from old Hep2O® or Acorn® fittings are not compatible with Hep2O®
fittings. Evidence: Cap marked HBP (Hep2O® is marked Hepworth); Metal grab ring.
(Hep2O® has a white grab wedge); 'O' ring not marked (the Hep2O® is marked with
the size); spacer washer (not needed in Hep2O® fitting)."

Anyway I feel a bit more relaxed now - thanks again.
