⚡ How to install earth clamps | cross bonding ⚡
HTML-код
- Опубликовано: 8 июн 2019
- In this video I install two earth clamps and a piece of 10mm earthing wire to a coper pipe, this is so that a plastic component can be installed in the pipe at a later date. By doing this you ensure that the electrical continuity of the copper pipe is not compromised, if the pipe was cut and a plastic joint was installed.

Apologies for this week’s video being a bit late, I’ve been tied up doing other things!
I hope everyone has had a great weekend 😉 (it was a bit wet here yesterday)
Tied up with earth wire, presumably?!
I just don't seem to have the time anymore. A few years ago, I could film and edit three videos in a day, now I'm struggling to film and edit one per week!
@@ultimatehandyman have you started a family or is business booming post-Brexit?!
I have two kids, one is 6 the other is 8, I'm only working on site three days a week at the moment (for the next few weeks) but still struggle finding the time!
@@ultimatehandyman well, what on earth are you doing then - fixing everyone's property in East Lancashire?
A great video. Wished I'd seen it before I spent money getting water and boiler pipe insulated!
Very 'down to earth' explanation ;)
Ha Ha ;-)
Thanks for the comment 👍
As usual Chez you put out a video just after I do a job!
It was a right faff working out how to get these bloody things tight when you are in a small, dark space under a sink trying to repair the bonding between the pipes.
I made a video about fitting these several years ago, and someone commented saying you can just pull them with your fingers and tighten the screw- something that has never worked for me.
Thanks for the comment 👍
The water supply shut-off valve outside my flat was replaced, along with a new section of plastic pipe replacing the copper. It never occurred to me that maybe I should install an earthing bridge across the gap. Thanks for the well made video.
Thanks for the comment 👍
douglasheld earthing bridge? Again clear to me you have no idea what you are talking about. Horses for courses. Get an electrician in. This is why we do 5 year apprenticeships.
@@garymckeown4278 what a ridiculous, uninformed and patronising comment.
Have a word with yourself, fella. Your heads on wrong.
Your videos are always useful and informative much appreciated
I’m glad you find the videos useful
Thanks for the comment 👍
Excellent video. Thanks for sharing.
You are welcome
Thanks for the comment 👍
Nice one fella , you’ve reminded me I haven’t done them all!
Thanks for the comment 👍
Thank you for the video! We use the same style clamps in belgium, but without the safety tag and usually without the locknut as well. But they do the job, I guess. Most piping is plastic anyhow these days..
Copper is still widely used in the UK, but a lot of plumbers use plastic pipe now!
Thanks for the comment 👍
I wondered where the video was ☺ All the best!
I'm trying my best to upload one every Sunday, but I'm dropping to pieces at the moment. If I ever don't post a video again, you know that the grim reaper has finally got me ;-)
Thanks for the comment 👍
Bring on the sure stop great bit of kit
Thanks for the comment 👍
Great work 👍
Thanks for the comment 👍
very good
Very helpful thank you :-)
You are welcome
Thanks for the comment 👍
Excellent, easy to follow and well explained as usual. Keep up the good work. Thank you
Thanks for the comment 👍
I put dielectric grease in between, that way, the copper doesn't tarnish anymore and the connection remains functional over time.
I hope that you mean "on top of", rather than "in between", as dielectric is an insulation.
The lock nut should be placed over the metallic label and then be tightened to hold that in position so it can be read. Not be left free moving where it can end up side on and less readable. Also allows me to put my wira 10mm ratchet to good use tightening nut whereas behind the label i can only use the jaws end as on the video. That is a deal breaker for me ! 😀 Otherwise great vid
If you do fit a SureStop I’ll be very interested. I purchased one 2 years ago and still haven’t fitted it! :)
My stopcock is pretty horrible so it always worries me when I need to isolate the water.
And I can’t seem to explain to the Mrs which way to turn it if I’m out and we have a leak. She’s an experienced project manager with a degree but stopcocks are a mystery it seems lol
Hopefully I'll get the video edited for next week ;-)
Thanks for the comment 👍
Might be worth fitting a ball valve as I have done in my boiler cupboard, taps all over the place to isolate hot and cold pipes and in need of replacement. Now its easy to tell on or off as it's written on the ball valve plus it's a simple turn of the leaver. No more taps for me!
Be interesting to hear what Chez thinks.

Thanks!
Now that underground water and gas mains are being upgraded to plastic supply pipes, how does that affect the earth bonding of properties?
Not sure, it depends what the latest regs say.
I guess that is one major advantage of using plastic pipes ;-)
Thanks for the comment 👍
Is the coiling necessary? I want to install across pipes just below a boiler. The installs I've seen use just a small loop between them.
No, you can just loop if you prefer ;-)
As long as your incoming gas and water pipes are equpotential bonded within 600mm and before any T branches in the pipework. Then you don't need to supplementary bond the pipes beneath your boiler. The casing under the boiler gives equpotential to the rest of the pipes. The copper for the Gas and water makes ground for the rest of the pipework. 18th edition regs now state if the pipework below ground to the stopcock or pre gas meter isolation valve is MDPE plastic then again no bonding is necessary. I just install it to keep the other Gas engineers and some of the old school sparkies happy. Either way consult an electrician if you're unsure.
If you really want to supplementry bond the boiler pipes. Then best practice is to keep the wires short, 6mm earthing cable should be suffice. Shortest possible route to ground.
Does a resin sink and tap need to be earthed?
Not sure, as I have not checked the regs for ages.
The tap might need earthing, if it is connected to copper pipes, if it is you best check with an electrician ;-)
Those stainless steel straps ever break?
I’ve never seen that happen 👍
Is is necessary to cross bond a shower if the shower is protected by a R C C B O?.
Not sure, I have not checked the regs for a long time.
I would just do it, as that won't cause any problems- but not doing it might do 😉
@@ultimatehandyman Thank you for your reply.👍
Manufactures instructions supersede all British Standards. Unless your instructions state otherwise, then No additional bonding is required other then the CPC in the existing twin and earth cable.
Where did you get the crimpers as I have been looking for some time
I can't remember where I got them from, sorry
I would avoid buying a really cheap pair though, as they are often useless!
Thanks for the comment 👍
@@ultimatehandyman I would like to meet you for a pint as I noticed your near me (Burnley)
I don't drink much unless I go out on a leaving do or go out with the lads. I'm so busy working and filming/editing videos that I don't have much spare time 🤔
Good video ! Hope you're not going to be installing a Sure Stop ! I go out to no end of leaks from them.
I am, I checked lots of reviews and most seemed positive!
Where do they leak from?
Thanks for the comment 👍
@@ultimatehandyman most of the ones I've been called out to leak from the main body, I went out to one in a utility room and it had made a right mess. I like the idea of them but I wouldn't install any after seeing what I've seen, and I know many other plumbers that have had issues with them. They're a great idea but need to be better constructed
I might make a few additions to the video now, I'd hate for people to install one and have problems with it!
You would think that, if a product was problematic- that the retailers would stop selling them!
Thanks for the info ;-)
@@ultimatehandyman I don't see them in retailers as much as I used to a few yrs ago.
Great videos as always 👍
It gets me why they earth water pipes unless its related to water heaters, kitchen appliances etc, here a girl was electrocuted 230vac was comming out the water and pipe, the fault was the main wires providing the house with power they were in contact with one another via corossion, metal oxide powder allowed the connection between neutral and active before the meter box , All rcds worked everything worked took the inspectors and engineers a while to fault find.
Do you have to earth a bath tub?
A metal one might need earthing, but not a plastic one.
You'd have to check the latest regulations
Can you explain why the pipe would need to be cross bonded?
It might be best if you ask an electrician, I just do it when I have to.
If you want a real laugh, just take a look at some electrician's forums and search for earthing and bonding, you will find plenty of confusing advice ;-)
Thanks for the comment 👍
A single pipe just needs to be bonded with a 10 square, there is no need to put a bond between a single pipe, if you have a few pipes in series you just link them all together! Also twisting the earth around in a spiral shape has been changed in the regulations, the more you twist the earth and use a longer cable the higher the resistance which essentially means longer trip times in a fault situation!
@@ultimatehandyman I am an electrician, by inserting a plastic fitting the other side of the copper pipe is no longer an extraneous conductive part and would not require bonding.
Just abit puzzled as it looks like the pipe is mains water pipe and stop tap ? If so this should already be already earthed with a10mm earth wire to the dis board, everything else is correct except if the mains water pipe is pvc then cross bonding in video would not earth pipe and technically if this is a stop tap if fed by lead etc and no 10mm bond already on it it is not earthed, although think that the reg’s have changed for mains water feed in pvc (don’t think they run a earth wire to mains pipe just check )
It is already earthed, but I'm cutting a section out (in the next video) to install a plastic surestop valve.
Thanks for the comment 👍
If I seen anyone on my job/site “forking” the cable they would be sacked.
Only way I would ever consider that if you fork it and leave a conductor longer and make a eye let.
Thanks for the comment 👍
What time do you call this😂😂 your slacking young man👍😁. Good explanations and demo👍
Yeah, I uploaded this Yesterday, but didn't make it live until I got to the computer- just in case I had a lot of trolls to block, as it's easier on the computer ;-)
Thanks for the comment 👍
@@ultimatehandyman please tell me you don't get trolls. Why the hell would you troll someone giving diy advice.😱🤔🤔
Oh, yes. I get trolled alright ;-)
But, fortunately I just click on "hide this users comments", then I don't see their comments- until they open another account!
👍🤓👍
Thanks for the comment, Wayne 👍
A spanner? You mean a wrench? 🔧
No, I mean a spanner.
It's only a wrench if I'm in the states ;-)
I don't get why water pipes need to be earthed anyway? I mean, there's no current running through them. I dare say there's a good reason, I just don't know what it is! I have similar to this under the sink in the bathroom, but don't know why.
If the reg's say they need earthing, they need earthing LOL
I cross bonded this, as it is necessary for when I install a plastic sure stop valve.
Thanks for the comment 👍
MM75 imagine this scenario. Your immersion heater develops a fault which causes the case to become live. This is connected to all the copper pipework, taps, radiators etc which become live also. As you have no earth connection there is no way for this electricity to return safely to ground. Your wife is making a cup of tea and turns on the tap whilst filling the metal kettle which is earthed through the plugs wiring, a path to earth is established THROUGH YOUR WIFE. Hence the need for bonding,
mike brown so the case is the exposed conductive part which requires connection to earth the pipe work isn’t. I’d be more worried if the case wasn’t “earthed”.
@@garymckeown4278 you could have poor wiring into an electic shower which comes loose and touches the copper inlet pipe, repeat the scenario from there.
I bet it's a filter you're going to be installing ; )
Nope, but Thanks for the comment 👍
Ah. Thought it might be a Fernox install. Thanks for keeping us in suspense. Look forward to the next one.
Not quite, I'm installing a sure stop.
Thanks for the comments 👍
Where do you buy your lugs?
I think I got them from CPC- fave.co/2WWOWJt
👍
I think there was a bit of illuminati symbolism when you wrapped the earth wire around the copper pipe - snake on a tree.
LOL
You could be right ;-)
Thanks for the comment 👍
Where does that electrical bond flow to the main earthing
Fairly useless for a apprentice to watch this video and I am an apprentice
🤔
