Slab Suction

I was admiring this radon mitigation device as it passes through the attic and almost missed the method of support. romex pipe support 1, romex pipe support 2. I think that'll hold her.[^] To think this was installed by a radon mitigation company that must have run out of strapping.

What can I say. They were idiots but they are not alone.

I found a CPVC hot water pipe yesterday supported at proper distances along it's length (about 20' worth) by being tied to a run of non-metallic sheathed cable using a small piece of wire.

Thanks Dom.

As I read further down the list of active topics, I saw the instructions for loading with Firefox but you beat me to it.

I appreciate the help.

Actually, it may not be done 'well' in swolsen's photo, I think NM cable is a great strapping material. Its got metal for strength and the plastic jacket to keep it from damaging whatever its supporting.

What else should be used for PVC pipe? Plastic plumbers tape? I'd take romex any day. Although with the recent spike in copper, the price of copper cable has skyrocketed.

Hi Erby,

You did it right. You just forgot the image tags.

OT - OF!!!

Hi Randy,

Actually there are hangers designed for PVC. One could also use the plastic or metal strapping to secure the PVC. You are correct; The use of NM cable was done poorly, and with time, may pull loose of the staples that were used to secure it.

This is something I would expect from a home owner, but a radon mitigation company?

Hello Scott:

Not sure if you belong to ASHI or not however, they have a nifty Radon checklist in the ASHI Documents & Forms area.

Hello Terence,

I am not a member of ASHI at this time, however I do plan on joining.

You have my curiosity. What does the nifty Radon check list comprise of; or is that for "ASHI only" eye's?[:-bigeyes Maybe I will need to wait until I join.[:-cry]

. . . or metal strapping to secure the PVC.

I didn't think metal straps were allowed on plastic pipe (even though we see it all the time)

Great photos, Scott.

I agree with Randy’s comments regarding the strength and durability of NMS cable. While the support system may not look pretty, if the fasteners are well-secured to the rafters and the supporting cable is installed so that its ends won’t separate from the fasteners, it will work. Supports should be installed every six feet or less. The horizontal portion of the PVC piping looks as if it’s sloped so that water draining from condensation, snowmelt, or rain won’t become trapped in the pipe or foul the fan and the fan appears to be mounted and secured in a manner that minimizes transfer of vibration to the structural framing of the building - so far, so good.

Hi Randy

Several sites pop up on a Google search. Here are two;

No; actually I never heard of plastic plumbers tape. Are you referring to Teflon tape? The stuff used on pipe threads?

You may be correct on the metal straps. I was more concerned about the pipe being properly supported. [:-magnify

Ah, thank you Kevin; I will check it out.

Got it. Thanks. Can't remember the last time I saw that stuff around here, even on the million dollar places. Its all metal straps here.

No go back to that second website you posted. The plastic tape is shown twice. They call it 'plastic hanger straps', I believe.
