PVC Conduit Question

[RDB85]

I’m looking to buy some PVC Conduit for some security lights rather than clip the cable. We don’t use it in work. But I know I need 20mm conduit but would I be okay using 20mm inspection elbows? I assume they just fit inside?

Be careful with the PVC Solvent it's highly inflammable.

Says the voice of experience?

Go on, what's the story?

 

[Mike Johnson]

No story, just look at the COSHH sheets.

Yeah, but it has a really groovy smell man.

Don't it just Man? Oh and don't light up a ciggy when using it, makes it better (worse) sorry bout that typo, just remembering happier times. Roof spaces were the best area to use it, just remember to walk on the rafters, not the plasterboard

 

[telectrix]

few sniffs of that glue, you coulkd walk on water, never mind rafters.

Don't spill it on the carpet either!

Don't spill it on the carpet either!

What the glue or the drippings from yer nose?

 

[Mike Johnson]

And don't spill it on the plastic around the front of the washing machine or tumble dryer, yes there is a story to that.

And if you get it on your hands don't wipe it off on your trousers, it attacks certain man made fabrics

Getting back to being a little more serious ...
Glue one end, both ends ?
ISTM that unless the fittings are free to move, then gluing the joints will prevent movement due to thermal expansion.
And on a vertical (outdoor) section, glue the bottom fitting (to seal against water ingress) but leave the top joint free.
(Grabs flack jacket and dives for cover) ... Discuss

 

[Mike Johnson]

IMO glue both ends, but ensure the fixing brackets allow movement, plan your layout so there isn't any right angle bends close together.

 

[davesparks]

Glue all joints and use expansion couplers as required

I know it should do this doesn’t it’s the same diameter. So it doesn’t push inside. Not sure if it’s the conduit or the fixings I’ve bought. The fixing are a brand make and the conduit was given to me.

I will get a photo to show you what I mean. I assumed that the fixings should fit inside, so I was a bit confused when they didn’t and thought do I need 25mm tubing.

Sounds like you v been given plumbers waste pipe!? S

Not all the time they don't
