Just had a contractor call me and stated that the he was going to run some exposed PVC and that the HO wanted the straps "glued" to the structure and not mounted with a screw or such.

While it seems strange to me I can not find anything that prohibits this. I'm sure I would need some sort of listing for the product (wet location, sunlight resistant).

Or he could just use that stuff that they advertise on TV.

Any thoughts?

I'm assuming you're talking about plastic/pvc straps and some sort of plastic/vinyl siding on the building. Seems like it would have to be a very powerful glue/bond to support anything of substance. If anything, it would create an eccentric force on the siding without proper penetration into something "meaty". JMO. :)
 
the customer came up with the crazy idea, let them pick the adhesive and write it in your contract that your not responsible for its effectiveness, and charge them an additional fee for being strange....

LOL!!!!
what the heck is this strange charge of $1000?
I like that one, and I'll be using it often,,,,,,,,scuse me sir, but you do realize that a strange fee will imply if you insist on being strange.

The glued up straps as small of an area it is, would still have to leave room for expansion an contraction.

PVC conduit shall be installed as a complete system as provided in 300.18 and shall be fastened so that movement from thermal expansion or contraction is permitted. PVC conduit shall be securely fastened and supported in accordance with 352.30(A) and (B) or permitted to be unsupported in accordance with 352.30(C).

I think this is one for the AHJ to decide what is securely fastened.
 
I think this home owner has been sniffing glue.

Tell him if he can come up with a UL listed glue that states this is an acceptable method for hanging and strapping electrical conduit and they accept the liability for it if it fails, then your good to go. Other then that tell them to call you when they are not suffering from the affects of having their head stuck up their --- well you know what I mean. Or you could just say NO it is not acceptable unless they can show other wise. Might be less offensive then my first suggestion.:grin:

Just curious - what is the listing on the screws you would nomally use?

I'll bet the HO is oncerned about steel screws and rust streaks. Perhaps you could suggest stainless or brass screws.

And show me the UL listing on your PVC solvent...

Wait a second, don't want to put my foot in my mouth here. My PVC glue has a CSA stamp on it... but it's made in Ohio? Now, would you be able to solvent-weld the straps to the vinyl siding?

(I love the first two warnings on my can: Do not smoke, Do not swallow Separately they're pretty clear, but given that swallowing could be construed as consumption, one might look at the "do not smoke" directive from a consumption point of view and picture somebody pouring it into a pipe or bong)

Around here , we call this fee the "DAT" (Dumb (make a guess here) tax)
 
I think that EC called John to get himself out of a mess.Probably was hoping John would say its not legal.What i see is an install that might last a few months and then fall off.Glad i am not an inspector on issues like this.
 
Just like that old show "Kids Say the Darndest Things"; homeowners can come up with the wackiest ideas.

There are epoxy glues out there will hold hundreds of pounds. Like the stuff they use to glue in foundation bolts or glue the rod markers down. Gotta be made to bond material A to material B.

Or as you say the stuff on TV, Mighty Putty!! That Billy Mays is a crack up!!

Just curious - would you use the method described by the OP to install conduit ? :)

That's about as far as I'm going to go to keep the homeowner happy. I don't mind useing the best materials but when it comes to crazy ideas I draw the line.

Glueing sounds like more trouble that it could ever be worth ( even if you could make it work it's a dumb idea).

Even if I have to tell a small lie and say it's against code it wouldn't bother me. No glue.

Yeah read all that, but still doesn't say you can't use glue.

Give it a good tug,if it holds then why not.Any logic behind why he is doing this ?

Not that was told to me. My first thought was that if he removed it he didn't want holes left in his "stucco", but then I thought if these straps came off they would really leave a mess.

UPDATE: Just got a call from the EC, said the reason was the HO didn't want any hole drilled in his walls. I'm thinking if the "glue" is strong enough to hold the straps, why not just glue the pipe to the wall?:grin:

The EC really doesn't want to do it so I told the him to look at the listing for the straps and they may say that he has to use a screw or a nail.

Forgot to mention the DAT to him.:grin:

Just when you think you've heard it all.
