A question about PEX; Does anyone know the maximum bend for PEX before it kinks?
I have replaced with pex plumbing and it is easily bent out to a 90 degree to where you want it, carefully put in will be no problem. Not as easy as copper or plastic as the pex bend has to take more room not to bend, not as cut and dried like the others. But certainly, in my opinion, MUCH easier.
This should cover the PEX install info

What fittings are you using? Press on, crimp sleeve or the Uponor ProPEX sleeves?
We just ran some water lines here at work and used the Uponor system and man is that slick. You heed an expander tool though but it is simple, fast and likely the most reliable join.

Thanks Tim!
Well Phil, not too sure at this time. I will be using PEX-B. I am considering the Uponor system, I need absolutely the most reliable joints. However, it's a relatively small project (longest line will be about 42' in combined length, plus 9 fittings.), so I wonder if it would be more cost effective to rent the tools instead of purchasing them.
Louie, I used the clamp on fittings on both the red and blue pex pipes from plastic, which is my regular plumbing to new fixtures and everything is fine. Wished there was pex when I redid this place originally in 1995 and I would have done all of it in pex.
Well if you won't need the expander tool after you job is done it may be best to rent one, you won't need it for more then a few hours most likely.
We bought a Uponor/Wirsbo manual expander kit on eBay. I think it was about $150 and that came with dies for 1/2, 3/4 and 1". The beauty of the Wirsbo system is that you basically create a tension in the tube and the sleeve that always wants to contract. The spring clamp rings will never increase tension if the material cold flows out of the clamping zone. It is similar to why a Corbin spring-style hose clamp is better then a worm gear clamp.
Here is a link to the Uponor PEX manual, everything you'd ever need to know.

bought a bank owned repossessed house. Either the former inhabitants, or the contracted maintainanance people cut out some of the copper plumbing, so it has some pex in it now.
It's easy to work with. I used a similar angle stop for a copper toilet supply.
Not a Shark Bite, a Brass Craft push on. No problems.

My fear are leaks Tim. Being on the 19th floor, it could be a catastrophe. That's why I'm keeping fitting's at a bare minimum. The less joints, the less chances for a leak.
Thanks for the link Phil. Now I have another question. I know PEX can withstand temperatures up to 200F, I am running 3 lines behind the Caloric stove. Should I insulate? The back of the stove will be about 3 inches from the lines.
Never heard of Brass Craft Mike. Thanks, I'll look it up.
If they were in the wall it would be NO concern at all. Even run directly behind the stove I don't think I'd worry. The area behind the stove probably doesn't reach 200F unless it is enclosed somehow. The lines are full of water so it would take a lot of heat to make them too hot.
I recently acquired a Frigidaire frost free upright freezer to replace my old chest freezer. I placed it in the "line-up", where the laundry/utility closet is going. It just barely fit. From left to right, two stacked whirlpool dryers, the space for the Maytag A107 washer, the GE Frost Guard refrigerator, and the aforementioned Frigidaire. Because the new freezer is so wide, I no longer would have space for side walls of the new closet thus, no where to mount light switches, outlets and the intercom.
So I've come to a decision. I have to let go of some of the appliances. It's gotten to the point there is simply no more room to fit so many appliances, and vintage electronics.
The Whirlpool portable dryers will be the first to go as soon as I find a decent Maytag DE-806 (blue panel) to replace them. Yes, gasp, I am going to live with ONE dryer. The Maytag A107 washer will be replaced with an A806 that is in comparable condition, I know, a tall order. Next the KDS 19C dishwasher. I was going to part it out, but I just don't have the time. I will swap out the upper rack with my KDS 58.
So in a nutshell, one dryer, 2 washers, 2 refrigerator/freezers, one upright freezer and 1 dishwasher.
My husband is doing cartwheels.

A new update. I have most of my plumbing supplies ready. As I mentioned earlier, I am going with the Uponor/Wirsbo pex system. Tubing is Pex-A. I have decided to add an ice maker connection and an outdoor hose cock. The dish washer will have a hot water shut off valve since I will not be using the dishwasher everyday. Each washing machine will have individual shut off valves as well.
It has begun. The intercom and light switch will relocated to a new stud wall.
Broke through the kitchen and dining room wall. Rough in.
Top: Conduit I am using to protect the PEX A tubing from the sharp metal lathing used in the walls.
Bottom: Is the drain for washers.
Well, the plumbing is complete. This is the first time I've ever used PEX, simple enough, but that expansion tool is tough to maneuver in tight places like under the sink for example.
First pressure test. No leaks from the PEX connectors, however, there were 2 leaks from the washer shut off valves. It was between the valve and the PEX brass adapter. All it needed was a slight tightening but, PEX is on tight, you can't twist it, so the only solution was to break the seal rings and remove the entire length of PEX pipe up to the next connector. Then tighten the adapter, and reinstall the PEX with the rings all over again. And it's a new install. Nothing can be reused. Major pain in the ass. So that's the ugly little secret with PEX.
Leak
The laundry valves and the PEX A transition fittings were NOT compatible, hence the leak. New valves and fittings installed, no leaks. Also revised the drain pipe, added a P trap. First wash using the Magic Chef (back-up) washer. Also installed the top shelf of the closet. At 10'2" in length, had a hell of a time fitting it into the elevator. Still have to do the electrical, framing work and find some affordable bi-fold doors. Doors have to be 2'3" x 96"(four of them), not a popular size.
