RIGHT. I don't take meds of any sort.

No way you need to apologize man, that's good stuff. Wish I'd read the info about Pex earlier too. As in "BEFORE WE REDID OUR HOME SUPPLY LINES WITH IT." That kind of thing.

Thank you

Before you dismiss PEX, you might want to read up on the benefits from a reliable source.

BTW, Qest 'Quest' isn't PEX.

Polybutylene is a form of plastic resin that was used extensively in the manufacture of water supply piping from 1978 until 1995.

Is polybutylene piping the same as PEX?

Lets just focus on PEX & PB piping. There are two common types of plastic piping which are known as PB (Polybutylene) and PEX (Cross-linked Polyethylene). ... So if you will be pumping water, or the pipes will be exposed to the cold, PEX is a better option than PB.

PEX is great SHIT! Chlorinated CITY water, like we have here in South Florida eats it alive. I see a 10-15 year lifespan out of it. I'm guessing you are in an area with well water that doesn't have chlorine in it. But all of the failures I stated are all reinforced below by the multitude of sites I posted. Not to mention all of the chemicals it leeches into your water. How many dumb contractors have you seen driving around with spools of PEX in the bed of their pickup truck baking in the sun for who knows how many days??? I see a truck with a spool of PEX in the sunlight everytime I go to a Lowe's or Home Depot. Plus it has NO dimensional stability- it expands and contracts with as little as a 10F change in water temperature and lengthens and shortens with water temperature causing it to both chafe through on clamps and holes in studs and expand and contract the crimps till they fail. Also all of the crimps and fittings dezincify with City water because all of the Cities pipes carrying the water to your house are copper. I WOULDN'T have it anywhere inside my home.

FROM YOUR OWN LINK- (What do you think this does to the longevity of the crimps and the crimps cutting into the pex because they don't expand?)

Expands up to 3X its diameter to help resist freeze damage

About six months ago we get a call from a client that had a pin hole leak in her PEX water line, we tear the wall open and find a cold 3/4" line bent to a 90 for a manifold tie-in leaking about 2" from the manifold. Figure that some how under stress from the sharp turn it may have weakened the pipe and caused a leak even though the pipe was not kinked. Today we get a call from same client saying she hears water dripping in her ceiling, My Partner goes over cuts ceiling open and low and behold another pin hole in the PEX pipe. This time it is in the middle of a straight run. Has anyone else had a problem like this? The house was built 1998 and has city water. pipe is supported with full rap talons about every 2', no signs of wear on pipe just a small pin hole. I thought that this stuff was to last forever or at least my life time!

Re: Pin Holes in PEX

Wirsbo just paid for a tear out in Wash. state! This is radiant. And this is My familys Buss.
On another project,there is bubbling on the exterior. They came out and inspected ,and documented. The 1st job was repaired this Month. Don't know the install date. Wasn't their project.

1. PEX had its issues. And so did copper and CPVC. Anyone with a prejudice towards one type or brand of PEX and fondness of another should know that not a single major PEX pipe/fitting system used in the US has been problem free. Here are some examples (7):

PEX-A (Uponor/Wirsbo and Rehau): dezincification of fittings and chemical leaching/odor (AquaPEX only)
PEX-B (Zurn & Viega): dezincification of fittings
PEX-C (Nibco/CPI/DuraPEX): cracked, leaking pipes
PEX-AL-PEX (Kitec/IPEX): dezincification of fittings

2. Water quality matters. A LOT. Factors such as pH level, chlorination and others have a direct effect on the life span and reliability of the system – including both PEX tubing and fittings. We’ve covered some of this here (PEX vs. Copper). A PB (polybutylene) pipe system, commonly installed decades ago and now accepted countrywide as “defective” had lasted only a few years in some cases, while in others exceeded the 20-25 year lifespan with no major issues. Why the difference? Water quality.
7. Give it some slack. Since PEX will expand and contract 1-2.5” per 100ft of length with every 10°F changes in water temperature, it should not be pulled tight during the installation. In case of 60F temperature rise, 100ft may elongate as much as 15”. Use tube talons and pipe clamps which allow for movement of the pipe without damaging it and make expansion loops on long runs of pipe which will carry hot water. Failure to properly secure the PEX pipe will overstress it and may cause mechanical damage and even ruptures.

Does PEX Piping Hold Up Over Time?
As more and more people are using PEX tubing over the past few years, failures are being reported. Most of the failures can be tied to 2 specific areas; the pipe and the fitting. The pipe itself has been known to fail when exposed to chlorine in the water or after being overexposed to sunlight prior to installation.
PEX piping has also been found to be permeable when exposed to some substances, including oxygen and some petroleum products, and can leach toxic chemicals from the pipe material. As for fitting failures, brass fitting used with PEX is caused by dezincification. This causes the fitting to corrode and eventually create leaks. This could mean replacing part or all of the PEX plumbing system.

There's already a class action lawsuit against PEX
https://www.classaction.org/pex-plumbing-lawsuit

— The stabilizers in PEX are highly vulnerable to breaking down under UV radiation — while some sources may claim that some UV exposure is acceptable, we advise that all precautions should be taken to shield this material from UV rays. Even fluorescent lamps and CFLs are to be avoided, especially where piping is routed through a ceiling and may interact with recessed fluorescent lighting. There are many shielding products available to solve this problem. However, PEX is best-suited to total darkness. An insurer can easily specify protection from UV.
— PEX is also known to be slightly vulnerable to chlorinated water and possibly copper ions, resulting from copper corrosion upstream. The temperature rating of the water must be strictly adhered to. Alone, these factors may not be worrisome in many applications. However, when combined with other aggravating factors, the aggressiveness of the water may amplify hazard potential. A test of water chemistry is advisable.

EXCAM_MAN I guess you have no response when you call someone out and they back up what they're saying with plenty of references, huh?
