Main Bonding plastic pipes

[Geordie Spark]

I quite agree, although I'd have preferred to see another inch or two of copper.

Well you can have that if you want.

The plastic straight coupler is demountable and reusable - it just unscrews - and the short bit of copper is connected to the stop cock with a compression fitting, so you only need a longer bit of 15mm copper and a new 15mm olive to reconnect to the stop cock, then shorten the plastic pipe - remember to refit the insert into it - and shove the coupler back onto it.

Personally, I would have prefered to have the whole thing in copper with not a bit of plastic anywhere on the job, but I'm old fashioned.

Well they seemed to be having a bit of bother with lunatics running around with guns and shooting people through the knee caps at the time and I'm rather fond of mine.

Is that all

hmm, i meant that the old bonding clamp is seized, I didn't try for long but the screw started to snap so i can't reuse that clamp, and as far as I'm aware the stop cock is old but functional still....

So that short bit of copper after the stop cock still needs a main bond?
I think the rest of the pipe before the stopcock is wrapped in something, im not sure. it was all a mess when i arrived as there was a gas leak with a drop of 8.5 milibar per whatever unit is used and the ceiling had been pulled down, revealing a second ceiling which was pulled down and not tidied very much at all

OK .. sorry I thought you meant the stop cock was seized.

As for the gas leak .. that cannot be ignored!!

Aye well .. I had been gigging around London during the '70s when they were trying to blow it up so I thought that since I survived that I wasn't going to tempt providence by stepping into the lions' den, but Cork I think I should have gone to.

when we arrived, the woman of the house said, 'i think theres a gas leak because my husband tried to pull the gas cooker out, and we smell gas through the house now, but it cant be that bad, we haven't blown up yet!'

clearly a non smoking residence otherwise it may be different...

but erm the bonding thing? can it be omitted? its a pig of a run if so (its not an excuse just if it isnt needed then that would be cool)

 

[seawead]

regs say it has to be bonded (within 600mm of tap - surely that's on the plastic?!). but what's the chance of anybody ever being exposed to a live fault and touching this section at the same time? (is it next to an appliance?) if it's miles from any circuits / appliances, and a pain to get a bond to the c/u, then i would leave it. if it's right behind the washing machine, bond it

Or reasonably practical ..... Is the rest.

"within 600mm of tap" could be as little as 1mm from the tap and that would be on the copper.

My view is that from the picture posted in this thread there is room for a bonding clamp on the copper IF IT IS NEEDED.

Another thought is what happens if that plastic at some time gets replaced with copper?

Would it need bonding then and if so why not now?

GS- Cork is corking (Tel).

Dont bother with the Youth Hostel though.

It will be under the kitchen units, and the sink will be near to to within 1-2m either side of the stopcock and obviously above it(i cant remember from the drawings) but the sink will be fitted with plastic pipes.

There aren't any circuits near except a socket outlet which will be in a unit 3-4 metres to the right to provide juice to a single oven.

I don't mean to reiterate what i ask, but it's just because the regs are so open to interpretation i would just like to hear you views.

thanks to all the responses so far...

I'll probably be shot down for this but imo, whats the worst that could happen if its not bonded strictly in compliance, or even bonded to met at all.....if its realy difficult to run a protective bonding conductor from met to this small peice of extraneous pipe work, then I'd either supplementary bond it or box it in and note on EIC...in all honesty whats the worst that could happen if all pipe work etc is plastic and this piece is hidden under the sink.

You asked a question and were given the correct answer. It's entirely up to you if you want to ignore that answer and happy being responsible for you're actions, or lack of them, depending on what way you look at it!!

 

[overskilled]

Just bond it and get it over with.....
If it wasn't for that stop cock being there, I would have considered boxing it in and adding a new stop cock with plastic each side....

Though in a recent site conversation Scottish Water said to me they are keen to remove lead water pipes supplying homes as they tend to leak (mainly as they are getting on in years....). Especially so when your doing building work anyway...SW guy I spoke to said if there had been a lead supply present they would have asked for a trench, installed a duct and alkathene pipework and then disconnected the lead pipework.

Il tel you one last time, if have plastic mains, you don't need it.......
