Everytime I get a plumber they are either ridiculously expensive, leave something dripping.... or both!!

I dont touch plumbing in my house as both times I've attempted it I've just got into a right pickle. I dont understand water, with electrics you do things a set way and it works, with plumbing I do it exactly as stated and then I get ... drip, drip, drip!!!

Anyway.. I needed the copper pipes channelled innto the wall rather than stuck on the outside and boxed in. They go directly from the stop cock (where the main bonding is attached). The chap said he would use copper. I get home and see a great length of plastic pipe stuck in the wall all the way up to and into the ceiling.... I have just spent the last hour getting a 10mm cable from the stop cock to the start of the copper pipe, had to drill a downlight hole in ceiling to access it!!! Luckily I'm just about to have the ceiling skimmed!!

The point is if I didn't know (a little!!) about earthing and bonding my house would now be left without all the water pipework bonded (there might be some parellel paths but thats besides the point)!!

Ggrrrrr...... I'm disappointed with tradesmen at the moment!! Apart from electricians who always do a good job :biggrin:
 
Now this good length of plastic has been installed, is the pipework after it still extraneous?

Well I did think about that Amp David, but with that argument we could all just fit a small bit of plastic piping after the stop cock and then forget about bonding so I thought I'd rather have my house bonded!

What you have actually done is created a really random bit of supplementary bonding, it's also a waste of time as it's not accessible for maintainence. If that was the case in new builds where pipe tails are installed in copper or stainless for astetics we would be bloody busy bonding them all.

If you are unsure, test the pipe work back to the Met, if you have RCD's installed then as long as the pipe work has a continuity to the MET of less than 1667 ohms or above 50k then there is no need to bond.

What you have done there my friend is hack a hole in your ceiling for bugger all!

Feel quite foolish and am going to sit in my shed with a cup of tea and Guidance note 8. :shame:
 
Have to agree with HT here. Once the plastic pipework has broken the copper pipe circuit immediately after the stopcock, then the rest of the copper pipework in the house is no longer part of that extraneous circuit (that's always assuming that it's a metal mains coming in to begin with, and thus needs bonding). The problem with plastic pipework comes about when we have sections within an installation which breaks parts of that circuit, but due to some of the copper touching other bits of copper without making a good connection, we end up with high resistance between sections. All that said, most installations end up with hot and cold pipes effectively bonded via the boiler anyway...

Give my mate Paddy at PPS plumbing a ring Steve, he and his oppo lee are good guys and reliable and decent enough, just google him for the number, he is a cheltenham POOF but a nice guy lol

Cheers Mike, I'll do that next time.

Nice to hear from you again mate ...
 
I wouldn't put copper pipe in the wall myself due to corrosion with cement and gypsum , would be better in plastic although its better if not buried at all really...
 
Hi,

In a way I'm with HH on this one, I see the plastic pipe as just a continuation of the supply into the property and the Bond has then been made at the point where the plastic meets the copper. With the number of properties now having water meters fitted any metallic supply is now virtually lost anyway. How many times do we read on this forum, ' you can't do xy & z until you have checked bonding is in place'. Many things happen in properties over time and I for one would do the same as HH. We don't give guidance saying, check to see if this is extraneous, the guidance we give says Bonding should be in place.

Regards.
 
Hi,
Yes I do, but with the information readily given out on this forum, it seems to sit unfavourably with the replies that are generally given.

Regards.
 
How so? The replies generally given are to check that bonding is in place, yes?

They don't stipulate bonding to what or where, just that it needs to be checked. The first step in checking that bonding is in place has got to be identifying the items which require bonding. You can't check that something is in place without knowing where that place is!

Oh and advice given on a forum doesn't overrule the regulations!
