Pex line and flair-it fittings question

[Frieberg]

On my 75 Argosy, i have decided to replace the copper (frozen and split) water lines with 1/2 inch pex piping. I have been researching as much as I can on this and so far I have come up with the Flair-it fittings as the best way to do it. At first I was skeptical of plastic fittings and thought brass fittings would be better like the sharkbite ones, but they are alot more expensive and it seems alot of other people are using the flair-it fittings and they are fine. Someone posted that one became brittle and something heavy landed on it and broke it. OK? So, secure the lines and fitting to protect them from that???? Any opinions on these flair-it connections and how many people have used them and either like them or not??????

Also second question reference pricing........ I have priced alot of these fittings through a few different places, along with the 1/2 inch pex tubing also. I've found these places in order from cheapest to most expensive,

www.thepexconnection.com (3.39 for a 1/2 x 1/2 x 1/2 Tee)

Flair-It Store - Flair-It PEX and Polybutylene Plumbing System (3.81 for a 1/2 x 1/2 x 1/2 Tee)

someone in another thread mentioned that they used www.rvpartsoutlet.com (they sell the tees in pairs and want 10.08 for 2 of them.... 5.04 for a 1/2 x 1/2 x 1/2 Tee) )

my local ace hardware in Tucson, Az (6.69 for a 1/2 x 1/2 x 1/2 Tee)

This seems to be the trend for most all the fittings and the pex tubing that I am going to need. The pexconnection.com sells the 1/2 inch tubing for 31 to 49 cents a foot depending on the type and length while ace sells it for 79 cents a foot. Does anyone that has done this before or looked into it know of any other place to buy the stuff, or have any other opinions on it..... Any help or comments will be appreciated! Mark

My trailer was Pexed by a PO with flair-it fittings. It has worked well over the years I have owned the trailer. I did need to correct one error that was made and bought the parts at pexconnections.

Look into Sea Tech Fittings. They are he easiest to work with and the prices I see are less than what you have posted.

This site will show you what is available, but i did not get prices there.

I am doing some repairs with pex. I purchased at Lowes, brand name Watts waterpex plastic, 1/2" tee $6.52 and 1/2" x10' pex pipe $2.97. I found out the fittings will leak if they move so the pipe is not in alignment, so in one area I used the plastic clamps to keep the pipe/tee rigid. I first tried Sharkbite tee brass from Home Depot, pricey so I switched to plastic. Also, plastic you can remove fittings without special tool, Sharkbite you buy a special tool. This is my first experience with this stuff!
