primer

[Shockedby277v]

Anyone ever use primer on underground electrical pvc??? Any objections??

 

[mdshunk]

I never have. The instructions on the Carlon site don't seem to make it necessary. I was lambasted several years ago on this site when I suggested that using primer was not necessary on PVC conduit.

It might leave chemicals in it that could damage the wire.

 

[Shockedby277v]

Usually I don't use it. I was asked to use it due to so much water.

Or dye my neutrals, like purple switch legs

If you do use primer, do the sparkies of the world a favor and use clear primer. Purple primer on conduit screams out "a DIY hack was here".

LMAO!!! GAWD ... I can hear the inspector already.

Lets think about what does to the pvc.Do we want our wire to get that accetone on it? After its dried i would think it causes no problems but why risk it.

Awhile back -on this forum or another one - that same question came up.
I responded that plumbers use the primer (and of course glue) to keep water IN; electricans do the same to keep water OUT.

Then someone sank my battleship.... no matter what you do, water will accumulate in a pipe underground.

Primer is a solvent to clean the pipe and help the chemical reaction of glue and PVC (by having clean surfaces)

Due to condensation. Do you think it would help keeping the actual water in the ground out though??

And perhaps clean wires too

Might add that you are not allowed to use primer on dringing water lines.

 

[Shockedby277v]

define dringing ???

 

[Jim W in Tampa]

define dringing ???

it something like drinking but its been long day

 

[Shockedby277v]

DOH! Same here shoulda caught that. Woops! I've used primer on drinking water lines. Dang DIY plumbers.

I did not hear that ....and no I do not look for primer

Does electrical PVC have any real taper to it? How about plumbing PVC?

Jim, where did you get the information that primer is not permitted on potable (drinking) water lines? If you read the instruction from most solvent cement (PVC glue) manufacture they always recommend primers. The purpose of the primer is to clean and soften the pipe and fitting prior to the application of the cement.

I have never used primer on PVC electrical conduit and don?t believe Carlon indicates it is necessary.

Was told that many many years ago,no longer sure who said it.I assume it would be bad for drinking water standards.

Nope.
The only thing, IMHO, that would keep ground water out, is a good seal on the joints - don't be stingy with the glue, give it a 90? turn, hold for 30 +/- seconds.
