Anyone know of any lawful impediment...

[traineegasman]

Sorry if my reply hurt your feelings, & I`m sure you were offended by someone who had given you an answer, who is obviously lower than yourself, intelligence wise...but ask yourself a question.....Did I ask YOU?? Don`t be so rude...Please....

 

[traineegasman]

It also may help if you can string a sentence together, in a coherent manner..... please take on board....

MOD

please see 10a

One practical reason for not reusing an old heating pipe is that the inside will be coated with iron oxide deposits (like black dust) which will probably cause problems with injectors and gas valves.

However if the gas pipe needs to be no bigger than 22mm you might consider using the old 28mm pipe as a duct or sleeve, providing that the 22mm pipe had no joints within the sleeve. It would need checking against regs. of course.

Every so often someone comes along who sems to have the ability to upset everyone whether intentionally or not. Tgm, it appears to be your turn. I don't want to get into a slanging match-I just can't be doing with it. But if you have an answer to the change of use question then please enlighten me.

 

[kevplumb]

did you not say part of the pipework was inaccesable so how do you propose to repair a leak in this section

BTW he mighnt be the most likable but trust me he aint the worst by a long chalk

 

[kaboom]

Chris thanks, but sadly it turns 90 degrees. I can see it all from both ends but can't get in there to fit a new one. I should be able to loop it with the powerflush to get it clean as possible but I wonder if that would be enough? Don't want any warranty problems.

 

[traineegasman]

Which would of course mean that when that pipe was installed it was meant to carry water, & all it`s meanderings were meant to carry WATER, suitable run , suitable pipe for WATER... you can see my point coming from a mile away...WATER pipes carry WATER......GAS pipes carry GAS...THERE IS A REASON.. But I`m too tired to explain........maybe tomorrow..

 

[kaboom]

Kev, I'd test it first. If it failed the pressure test I'd carry on and do the detour. If it passes it becomes part of concealed pipework.

 

[kevplumb]

suitably ventilated of course
ask yourself how it got there

 

[kaboom]

Tgm, its 28mm copper tube with end feed joints, even the 90 is nicely pulled. So what's the difference? A reference will do!

 

[kaboom]

Kev, If I wasn't able to do the detour or use the old primary I'd have to rip out the panelling that I can see behind, lay the pipe and put it all back how it was. So nothing is different, just having never used an old water pipe for gas thought I'd ask if anyoine could see a problem with it- and I meant with relation to inside!

 

[kevplumb]

what i am saying is if it can be put there to start with it can be replaced

 

[kaboom]

Of course Kev, just a matter of how much repair. Customer would rather I go a different route, unless of course, I can use part of that old primary!

There's no regulation I know of to stop you, but I'd be concerned about what lines the pipe , as above. If it has a layer of black magnetite, it probably wouldn't be worth trying to clean it out, thougha powerflusher hooked up with DS40 should do it. Dry with a vac.

I used a 28 today which had been put in by someone else. He'd water tested it to 9 bar! It didn't leak on 20mbar either!

 

[traineegasman]

WOW, these guys are being very generous lately, which is unbelievable, six months ago they woud have probably tore you a new ass if you mentioned gas....they are getting all modern which is awesome..keep it comin` ol` gas dudes....
