20mm PVC conduit crossover / hopover?

[overskilled]

Don't do much conduit work...finishing my garage wire up and socket conduit needs to hopover the light circuit conduit. Can you buy these ready made or is it a case of bend your own?

[davesparks]

It's a case of bend your own.
It's known as a bubble set, or saddle set or a few other names

 

[Sintra]

Or you could use an intersection box.

I can't work out if your kidding or serious lol

Must have circuits in seperate conduit!

:lol:Ask a plumber to do it:lol:

Which reg is that then? I must have missed that change.

They are..mainly as the lights are broken up (to allow me to have light while fixing another) and it results in that 20mm being on the full size..

Got the spring already, just a matter of time saving, why spend the time bending it when you can buy off the shelf...

I didn't mean you have to have them in seperate conduit lol, I meant that he must have had them already wired in seperate conduit so needed to go over the lighting conduit already installed, this may not be the case was just having a guess.

 

[Hellmooth]

Good timing lol! How big is the been, surely it'll take you longer to buy it off the shelf than bend a piece of conduit?

 

[7029 dave]

DIY = .. .. yourself.

Cheers. Thought they'd sneaked a change in!

And I agree bend it yourself - a ready made 90 degree bend costs almost as much a 3m length of tube.

I've never seen a pre-made "cross-over", presumably because if you wanted to cross a 4" soil pipe, a 40mm waste pipe and a 20mm conduit you'd have to buy three different size fittings. There would need to be hundreds of variants to cater for all possibilities.

Bubble set in pvc takes no time, do the centre bend first as with steel.

Thats what I was thinking in the interests of lazyness

Business opportunity for someone then...money to be made...

 

[Risteard]

Definitely a bubble set is the obvious answer.

Small adaptable box
Notch the back to fit over the lighting conduit
Bring the socket tubes to each side of the box at wall level.
No bending required.

I quite like this idea...novel thinking

And if some bright spark comes on in minute shouting I.P rating Zero, then use a small piece of flex conduit within the box to link the tubes..

On the Commercial sites I work on it's quite normal to see straight tube then flex conduit to jump a beam or other obstruction.

 

[Hellmooth]

Has anyone mentioned using a bending spring............

 

[Hellmooth]

Gives you some thing to stare at for 5 minutes and be proud of

At the 3rd attempt

 

[Lagentium]

If it's in your own property, I'd strip it out again and join it all together, making it look neater. If not and you make your own bubble set, with you not doing much conduit, have a few bashes at it first and don't be worried about throwing an earlier attempt away, there's an interesting technique to warm the conduit up to make it bend easier, just make sure the wife doesn't walk up behind you while you're doing it, she may think you're doing something else........

 

[7029 dave]

IMO I would not heat it up or try bending it over your knee, it's all about hands.

 

[Lagentium]

You must have a fair pair of hands to do that without bending it over your knee! Or are my hands a bit small?

LOL you do know that plastic conduit bending with spring is all about hands, not to say you can't with knees, I bend steel with the legs of the bender too. (tip for you)

 

[Hellmooth]

Why wouldn't you heat it up or bend it with your knees? Having something to get purchase helps in general.

Struggling to picture this... How do you manage that?

Because the next time your stuck on a job and short of a few manufactured versions it wouldn't half be handy to have learnt to produce your own sets accurately and quickly everytime, I can bend and form one around my knee faster then plugging and glueing manufactured bits together - plus a smooth pipe bubble set looks more professional than a load of plug ad play pieces IMHO, although it is your garage at the end of the day

I learnt this from an old sparky, just to take a bit out of an set or tweak a bit, how can I explain this without showing. If you don't believe then I can't help, but not telling fibs.

 

[DPG]

Who'd have thought a thread about benders would get this much interest Daz

 

[Hellmooth]

It is in theory a simple 5-10 min job lol, especially as the OP already has the spring, I think it looks a lot better done with a bend than using pre made bends/junctions.

It is not simple, any form of setting conduit whether it be plastic or steel takes practice.

[Hellmooth]

We're talking a small crossover in a bit of PVC conduit, not tens of sets of metal pipe here.......

 

[Hellmooth]

Just watched all the video, completely missed the point, what was the relevancy of it?

 

[Hellmooth]

He could have used his knee to start the bend and got the same result, and he did heat the pipe up lol?

 

[overskilled]

Personally bending conduit either goes well or is a disaster entirely....lol

my own garage so not a major issue having a few tries at it...

bloke in the video looked a bit lethal with a hacksaw tbh...

Yes it can turn into a bit of a mess lol, 5 lengths of conduit later :29:

I was pushing the idea as it is your own garage so even if it is off slightly it's no big deal!

Yeah he was lol, at least he smiled a lot though........
