Need to glue up one joint for an electric outlet in her planting bed. I had a can of gray electrical PVC cement, but it's dried out. The big box store carries a small can of cement for $5. Knowing that it too will dry out, I'm reluctant to buy it. Thoughts on using regular plumbing pvc glue instead of the electrical specific product????

It's more of a solvent then glue. There is some transitional stuff that works for PVC and ABS so maybe they arn't too far apart. What about nail polish remover (acetone) or contact cement remover/thinner? Try on a scrap piece to see if it goes gooey.

EDIT, Sorry, I was thinking ABS. Not often I think about PVC for plumbing. Can't imagine it would be any different. If anything it might just be a formulation issue concerning potable water.

I've heard, but can't prove it, that the regular PVC glue affects the plastic covering of the romex. If you can be sure that the PVC glue doesn't come into contact with the plastc, it will work fine.

PVC is PVC. Read the product descriptions on the Oatey site, and you'll see the difference in some of the products is for the size of the pipe, and some is in either gray or clear. But they are all rated for potable water, pressure pipe, conduit and DWV.

PVC joint glue will work. Do not run Romex inside conduit. Strip the outer cover before putting it in conduit. Or just get THHN strand wire and run it.
As with everything don't go overboard with the glue. A little will hold a lot for a long time.

Is it a rule or code not to run Romex inside? I do it all the time to protect wire and it works. Is there something I should worry about?

Romex is covered in vinyl to protect the wires but holds the heat. Inside conduit the heat has no place to go and the wires will get hotter than in open air.
Licensed electricians will not run Romex in conduit. I cannot site the code on this but it is not done in practice.

I too would be curious about code. That would be a waste to strip romex. I have put romex in PVC conduit and buried it to avoid buying expensive direct bury romex. Not saying it's code though. I would be guessing that the jacket isn't temperature rated to be in a raceway. And a 14/2 romex might exceed conduit fill calculations for a 1/2" conduit.

This is the code ref regarding romex
300.9 and 334.12(B)(4) are your Code references.

A point to ponder. 2005 code requires romex to be run through conduit when it passes through duct work such as return air when the floor joist are used as the return air duct. The conduit must be sealed to the duct but not to the wire. In other words air must be able to flow around the wire.

Something i've found to help keep things from drying out, is to store the container upside down.

+1 well it slows it down drastically. But you'll need channel locks to open it.

I do irrigation ,pvc cement will work on pcv , electric gray or white , and sewer pipe, green . I have used gray electrical pvc couplers on white pcv pipe , no problems

By all means Yes, you can use regular PVC plumbing cement.

YES Since I discovered that my glues last forever.

Interesting. Unless I'm in the middle of a big project mine almost always set up before they're empty. Headed to the garage to flip mine over now.

If the jokes on you about Cqaigy2's remedy of turning the can upside down then the jokes on me too. I'll try it. Worked with this stuff about all my life and never thought or heard of this before. Thanks.. By the way it makes great on the job hand warmer. Just build you a little mound of dirt with a small indent pushed in the top like a volcano put in a little and light it. Burns a good little while. Only do this if somebody else is buying the glue.:)

The glue gets in the gaps of the lid seal, then dries forming you a new seal. Hence the need for channel locks to reopen.

Just don't try this with the primer or cleaner. All they do is run out and make a mess. :)

Another vote for storing the cans upside down. I used some glue yesterday that I'd bought back in April and stored that way. I just bore a hole a little bigger than the cap in a scrap piece of 1x6 to keep the can a little less tippy

Plumbing glue also works well on PVC trim and moulding...couple of fancy pieces in wet locations, like under the kitchen window in front of the sink, so I chose to use the PVC in the same profile as the wood I was using elsewhere.

Glued the miter cuts for the "returns" on the ends into the wall, worked slick, and set up fast.

I think part of the confusion about conduit cement comes from the name on the gray cement label. It's called Gray PVC Cement. That means the color of the cement is gray, not that it is made for gray pvc pipe.
