FWIW Family Handyman magazine has a PEX plumbing installation tutorial at:
http://www.familyhandyman.com/DIY-Projects/Plumbing/Plumbing-Skills/plumbing-with-pex-tubing/Step-By-Step
It may be useful to somebody.

A couple years ago I developed some leaks in the older style grey plastic piping.  I found out that a lot of that stuff was discontinued and folks were switching over to PEX.  I knew virtually nothing about the stuff, and found a couple of web tutorials like the one you listed. I decided to give it a try. I know there are folks that swear by the Shark Bite fittings, but I just didn't care for them (plus they are expensive).  I decided to use the crimp style fittings and invested in the crimping tool.  Great decision.  I ended up completely replacing all the grey pipe with PEX. Red for hot water lines, blue for cold.

The grey plumbing system was a total fiasco. Manufacturer got sued and had to replace A LOT of already installed systems. Was replaced by CPVC (the yellowish plastic). Whoever has grey PVC already installed should seriously consider total replacement before **it happens.

I still have the Qest gray fittings.  I installed them in '94 and have been zero failures.  I realize that I will eventually have to replace the entire plumbing system, which will be fairly easy with all plumbing accessible (one of the main reasons my conversion took so long-making all systems accessible).  I know that Pex also has screw type compression fittings.  Does anyone know if those fittings are the same as the Qest fittings?  Good Luck, TomC

I am working on one of my apartments right now, and putting in a new kitchen  in one. I have used cpvc for years, but the PEX pipe at lowes isnt expensive and looks like the crimpers are about 50 bucks for each size on eBay.  I am going to try the PEX now that I read this thread, cause I hate the cleaner and glue, not to mention there would be less elbows, etc necessary. I don't want to mention cracked cpvc pipe in bus conversion several years ago that made a bit of a lake... Pex might solve that...

I have used the pex compression type fittings you speak of when doing repairs to the quest pipe with good success.  they are interchangeable.

Thanks pipopak, Good info for guys using pex.
I have been using PEX for ten years now and I love it. In all those years building houses, I only recall one leak. I believe it was a bad fitting.
As far as the Shark bite fittings, They are real good fittings. They kinda work like the air fittings on your newer trucks, just push the pipe in, and your done.
They are very expensive and I wouldn't use them on a whole plumbing project. I only use them in the places you can't use a crimper. I did buy a new crimper when I plumbed my bus. It is more of a ratchet style crimper and uses more of a band style clamp instead of a crimp ring. The clamps are more expensive than the rings, but not too bad. The nice thing about this system is, you only need about 8" of space to use the crimper and on a bus there are a lot of small spaces.

I have heard a lot of people say you can't make pex look as nice as copper or cpvc, but you can make it look real good. They make 10' straight sections like cpvc and I just use more 90's and straps to make nice straight runs.

As far as freezing, they say it can freeze. I would worry about fittings though. In my bus I made sure I didn't use fittings in places I couldn't access.

We ran the new Pex, not the gray, in Mrs. Jones and a little copper for the tight corners and it is holding up great! We also put it in the many houses we built. We are sold on Pex. M&C  Grin

Pex is made from nasty chemicals from what I read today lol reading today's paper AZ is thinking about joining 5 other state in a class action suit over Pex pipe and fittings may not be as good as you guys think.
Fwiw Quest is still used in the RV market I am not sold on anything made from chemicals I worked when I was younger where they made VC a component for PVC that is nasty stuff too this day I will not drink from anything plastic glass or nothing and no China  made glass either
 
BTW a ? for the Callie people is PEX approved in California now it wasn't a few years ago if my memory is right

good luck  .

I dont know if it is aproved or not.... I havent got to that part of the conversion yet. I do know it is not in my home and it isnt in my favorite hardware store... Ever since Desi said he had sex/pex all over the house and loved it, I have been looking for it so I could maybe get the same kind of joys  Grin Grin Grin

We've been usng pex for years, and pretty much our only failures have been from trim carpenter nails....which, we've found, can seal around themselves and actually hold pressure for up to eleven months! Wink. Ask me how I know! Cheesy

We did do some repairs on an 8-plex that had some lines that split.  It seems that the unit sat, unfinished and exposed to sunlight, for quite some time, and since the pex used was not UV resistant, it appears that sunlight degration was the cause.  All non-uv safe pex shoud be store out of the sunlight and exposed pex in slabs should be protected if construction halts for an extended period of time. 

Other leaks have been due to damage caused by concrete guys, famers, etc....., but  we saw that in copper houses too, so really no difference there.  We did see a gopher chew through a line once (we think), but then we've seen gravel or rocks eat through many a copper line too.

Over the years, we've seen quite a few units freeze during construction, (and in finished houses) during extreme weather, but the only freeze failures we've seen have been the brass ball valves and fittings.  I find it amazing that if there's a leak on a copper house, someone repairs it and no one thinks twice, but if it's a material other than copper, people immediately want a class action!  Oh well, guess that's life.  Christy Hicks

Well, one nice thing is that when we do a pex job, we don't have to go back and replace the lines that were ripped out of the ground that night by some low-life, lower than worm-dirt, lazy-butt, jerk-off thief! 

The pex pipe itself is pretty reasonable, but the fittings, being brass, are not exactly cheap. . .otoh, nothing in the world of commodity pricing is cheap anymore. . . if the public only knew how high materials really have climbed over the last few years, they'd realize that the cost of EVERYTHING is going to continue to climb as the economy improves, because currently, most of the chain, from manufacturer to dealer, has absorbed a large portion of those cost increases, but at some point down the line, when things are indeed improving for sure, end user costs will have to climb.  Sooner or later, companies are going to want to make actual profit again, instead of just being satisfied with keep their employees working and breaking even, IMHO Wink.

There is no way I would use copper in anything I plumbed of my own. . . the pex doesn't corrode, it doesn't split if frozen, and it is so easy to make modifications to the system, that I can't imagine wanting to use any other material.  Of course, we haven't had problems with our poly in our own home, which has been in for over 20 years, including the year we were in MN during a cold snap, and thinking he was doing us a favor by shutting off the breaker that he thought went to our well, my father-in-law actually shut the breaker off to our heater, ha ha.  Walked in the house upon arriving home, and immediately told Larry, "Something's wrong. . it's too cold in here!"  Huh hahahaha good times. . . ice skating in the kitchen, burned up well pump, New Years Eve party planned for the next day. . . . just another one of our mis-adventures with a happy ending.
