Perfect Size

[D.McLean]

What's the most common size pipe wrench used in HVAC/Plumbing service? I've found that over the last ten years, a 18" wrench has served me well in about 85% of the jobs I've done. (We have wrenches up to 48")
Let me know if this is an question you've ever pondered.

I carry a 12", 2-16" and an 18" wrench at all times with my two 16's getting the most use and the 18 or a 24" when we want to get really serious.

a rigid hd14 is my pick here, light enough to carry in your tool box and heavy enough to get the job done!(sometimes with a little persuation, lol) http://www.ridgid.com/ubb/cool.gif

I use the 18in and if I have problem I put a 2ft pipe on it. This has worked on some real old pipe and never failed me.

I think residential plumbers would use a 14" while commercial guys use 18" wrenches alot. It all depends on the job but with a cheater you can always make the wrench more powerful.

14" aluminum is my choice.

There is a right wrench for every job. I carry a 14, 18 and 24 aluminum, a strap wrench and a little 8" steel pipe wrench. Never use a snip (a piece of pipe over the handle to increase leverage) Better to get a bigger wrench or a couple more hands. You can ruin the wrench, especially aluminum pipe wrenches or worse yet hurt yourself.
