Hep2o pipe inserts?

[Mike Jackson]

It's got nowt to do with the suitability of the products for the application. It's all about the approval of the products. Products for use in secondary hot water circulation systems need to be tested and approved separately from products used in a normal hot water system. The cost of testing and approval isn't worth it for the limited market.

Slightly different to the advice given by bpec and building control. And I believe wras

I was told on a job a long time ago you had to put 18bar of pressure in to speedfit to open the joints up when comissioning it never checked if this was rite just got out the rothenburger and did as i was told. I definately wouldnt do that without inserts. Only time i dont use them is when im putting a speedfit fitting onto copper as its obviously stiff enough.

 

[Ermintrude]

18bar? Speed fit only rated 1 bar at 90c?

5 bar at. 25c

 

[IDCHAPPY]

Christ, I'd hate to be in that house with 18 bar in the speedfit :lol:

 

[Ch4 plumbing]

I'd hate to have to pump it up by hand, must have arms like the Incredible Hulk!!

 

[acecharly]

Ah i apologise, 2 bar for 10 minutes and 10 bar for 10 minutes.

Hep2o defiantly told us to pump up to 18 bar, and leave for 20 minutes,they came on site giving us training on how to fit this new fangled stuff.This was about 15 years ago,I know the test procedures have changed since,but it was defiantly 18 bar.And yes it was hard to pump up by hand but it saved on Gym fee's:stooge_moe:

 

[Koogatubac]

18 bar is crazy... Far too much to test.

I have pumped a town house by hand and once i hit 3 bar my shoulders, arms, hands and even everything started turning green! It would send me running around the site shouting 'PLUMBER SMASH!!!' As i grabbed all that plastic!! And then once again, defeated that plastic demon while the priest was beside me reading extracts from the holy bible!

PLUMBER SMASH!!!!!!

Test hep and polyfit every day on sites to 18 bar with a rothenberger pressure tester........pricework........£20!!

 

[IDCHAPPY]

At 18 bar you should have an isolation zone of the whole house, even plastic firing at you at 18 bar will cause serious damage..

 

[scorps]

That's why you loop all ends and never put blanks on if a fitting comes apart it'll still be connectedto the other pipe, like I said hepworth came out and trained us

 

[Ermintrude]

Hope ur wet testing and vent all the air off. Compressed air at 18bar makes a lovely jam from you skin and connective tissues.

 

[scorps]

It was wet testing and done to heps instructions. Does anyone air test hep or speedfit?

 

[gassafe]

Air testing o longer allowed due to health & safety etc

but yes, I still air test... Half or 1 bar just to check no open ends etc...

 

[scorps]

On site work 1st fixing, a bit of spilt water doesn't matter so no need to worry about any forgotten open ends apart from air testing being dangerous it would also be useless cos if you had a small leak you would struggle to find it,

 

[stratplus]

Always with water. (and a hard hat)😀

 

[scorps]

And wellies

 

[acecharly]

Thought i was rite about that, i remember at the time being a bit scepticle about pumping to 18 bar. Air will release 7 times quicker than water i seem to remember so i wouldnt use air over 1/2 bar to test. As for 18 bar its not that hard with a rothenburger its the filling before thats the worst from 3 up to 18 bar would literally be one or two at the most pumps on a house size system id say.

3 to 18 bar one or two pumps, more like 200 and two more buckets of water.
Got to 18 bar on hep couple weeks ago and after 5 mins a 10mm pipe split!
Week before another trade person accidentally trod on a pipe at 18 bar and it sheared at the fitting. Must have jumped out of his skin lol

 

[northcarr]

Well I've never heard that :cry_smile:worked on massive new builds all with Hep secondary returns.I won't sleep now

Me to lol.

 

[hurdy]

HI GUYS ITS HURDY:sorcerer: AS A CONSTANT USER OF HEP AND BARRIER I WOULD NOT FEEL SAFE NOT USING INSERTS,IT WOULD KEEP ME AWAKE AT NIGHT KNOWING I HAD NOT INSTALED THEM,SO I FEEL IT IS A MUST.REMEMBER THE PLUMBING GODS ARE WATCHING.HA HA SEE YUO SOON:wazzzup:

 

[Ajones_17]

I never used to bother and have never had a pipe blow off. But nowadays I'm less of a cheapskate so always use them, just in case :28:

 

[Combi]

I saw a job once were they didn't use them and almost every fitting was leaking

Sharp edge of end of plastic pipes probably damaging the O rings in the fittings, I guess?
