Change over to pex


I want to change my plumbing over to pex, been looking around at options,
there is uponor, viega, watts, nibco, apollo, cash-acme. Uponor has its own
clamping system, the rest can use clamps or crimps. I like the uponor tubing
but not excited about spending 400 dollars for clamp tool, had one plumb supply company tell me that I could use brass fittings and stainless steel clamps with the uponor tubing. What success has anyone had with different
kinds of tubing and clamp system

Perhaps we could start with why you want to change your existing plumbing over to pex? Are you having issues w/ it? Pretty big job?

The topic of which system to use for PEX has been discussed ad nauseum on this forum for at least two years. Just do a search, you will find every possible opinion on crimp, clamp, expansion, and sharkbite fittings.

The simple crimp rings have work fine for me for many years.
I can find them anywhere.
The other systems also work fine to but like you pointed out why pay all that money for a tool your going to use on one job.
May be able to find a used tool on Craigs List or Ebay.

For a whole house I'd be buying my materials on Pexsupply.com.
Last time I checked there price fot shutoffs was almost 1/2 of what Home Depots price was.
Run 3/4 main runs, and 1/2 for the supplys.

We live in a two story house built in 1903. About 20 year ago I wanted to get rid of the galvanized pipe in our house, so I put in new copper through out. About 2 years ago noticed this bluish green tint in my sinks then in the tub, then in the toilet. You can use soap scum remover and get rid of the tint then in about 2 to 4 weeks you start to notice it again. I've found that if I remove the faucet strainer and fill up my sink with cold water I get a few bluish green flakes in the water, if I fill it up with hot water the flakes are grey.When you put the strainer back on you don't notice them, somehow the strainer breaks them up and there is nothing on the strainer screen. I checked with my neighbors and they don't have this problem, I called the city water department and they said there is no complaints like
this. I've had 2 plumbers come over and showed them, said they never saw this before, not sure what to do. Plumbing from street is galvanized pipe to water meter, then copper pipe to a whole house filter, then to a water softener then the rest is copper. I've looked on the internet and found somethings about possible chemical reaction with the copper and water, some people have stated they get small
pin holes in their copper pipes causing leaks. I don't want that.

#1 Get the water tested.
The only place there will be an issue with corrosion is right where the copper and old steel pipe make contact. There should have been a dielecrtic union there.

Have had water tested by city, said okay. Put a dielectric union on water pipe right after my water meter about a year ago, no help

Did the city test the pH? I found this article which has some good info. I am not endorsing the company or products.

Can't remember, when I took the water sample down to the city water manager he did several test, they were normal. Strange thing is my
neighbors are on the same city water and don't have this problem
Thanks for the article I'll look into that

Copper pipe will oxidize in acidic water. Typically this is a problem with water with a pH less than 6.8 or so. For more information, see http://www.cleanwaterstore.com/techn...pipe-corrosion

See also http://www.thisoldhouse.com/toh/askt...212564,00.html

The blue color is one or more varieties of copper oxide, or possibly copper chloride if your water is chlorinated (municipal water usually is). You can also get oxidation from the acid paste flux used when soldering copper pipe. This is mostly a problem if the water is acidic, and the installer failed to wipe off the flux after soldering the pipe. Typically this would show as a discoloration on the outside of the pipe, not in your water.

I suggest you get your water tested for pH and dissolved minerals. When you have accurate information about your water, you can begin to narrow down the possible causes. Also check your piping to see if there is residual flux on the joints.
