Nope. Just watch out for them revenooers ...

*There are benders for copper available. They look similar to my conduit benders. I have never tried to bend copper pipe.

Why do they call them 45 degrees? Look at one - it's not 45 degrees, it's 135 degrees. :-)

Can one safely use an EMT bender on copper pipe? My guess is "no", but don't know for sure.

I had a plumber tell me not bend rigid copper. Period. I guess there is flexible and rigid copper pipe...learn something new every day...

[Doug Miller]

Yes, I know that. I also know that if you go to a plumbing supply house and ask for a 135-degree ell they will tell you there is no such thing.

There are similar fittings known in the trade as 22.5-degree and 60-degree ells; what do you suppose are the actual angles of those?

Hmm...the 22.5 is probably 157.5 degrees because why would you want such a tight angle? Or how often would that actually occur. I didn't know they made those - the only ones I've seen are the "45" degree bends. The 60, my first guess would be an acute angle of 60, but that is a pretty sharp bend, so the 60 is really 120 degrees?

I'm guessing that the true angle of the bend is (180 - ), not zero plus the number. So a 90 is 180-90=90 degrees. A 45 is 180-45=135.

IANAP (I am not a plumber)....

[Doug Miller]

You got it; that's how they're numbered. Don't ask me *why*, though.

[Jon Danniken]

Not everyone can be as totally awesome as you think you are, Steve.

That's not the right type of bender for copper. If you feel that you want to try it anyway then just pack the tube full of sand before bending.

[willshak]

Really? Then why do they sell them for PEX?

[Pete C.]

They sell them for people who don't know how to use a crimper and the normal PEX fittings.

[Harry L]

It's REALLY how many billions the government spent forming committees to study the problem.

[Ed Pawlowski]

You need an anti-scald valve. Pressure may drop, it it won't go too hot.

Twenty years from now I'm going to be a plumber. And I'm going to get filthy stinking rich replacing all of those sharkbite fittings that people installed twenty years ago cause they are all gonna leak bwahahahaha...

Seriously - people are relying on a rubber o-ring to make a seal, and they are going to seal this in a wall??? Know what rubber o-rings do after 20 years or so? The more I look into PEX, the more I like it and the less I like the sharkbite fittings.

Using pressboard for exterior siding was a great idea also. Until it started to disentegrate ...

[willshak]

That doesn't mean they have nothing to do with PEX.

I have a hard time understanding modern man. There was a time in this great country of ours when people were self-sufficient. Everyone knew how to obtain food in one form or another, take care of their dwellings and transportation and they never stood in line for anything. Technology has bounded forward but that doesn't mean a single person can't deal with most of it. I was talking to a doctor friend the other day when I remarked that I can understand and repair just about anything except the human female. *snicker*

TDD

[Steve B]

I used some of those Shark Bite things to repair a 3/4" line at my cabin that was in a hard to get to location. I was skeptical, but after using them, and it holding for over a year now, I'm sold on them. A little spendy, but when you have an odd spot, it's Tinker Toy simple. Bing, bang, boom. Done.
