Most of the regulations from the Obama administration working their way through the courts raise an issue concerning Chevron deference. The Supreme Court has before it a case, Esquivel-Quintana v. Sessions, raising the question whether Chevron deference trumps the rule of lenity in criminal cases. Auer deference has also come under attack in recent years. As with Chevron, in some circumstances the Court has declined to apply Auer deference altogether. Christopher v. SmithKline Beecham Corp., 132 S.Ct. 2156 (2012). In other cases, individual Justices have argued that it is time to reconsider Auer deference.
Brickeyee is on the point. ALL PEX piping uses some sort of Barb fitting with a compression ring. I have never ever heard of a single failure with this type system. Compression fittings use a ferrule either brass or plastic. The brass ferrule bites into the pipe wall, but the plastic ferrule does not. It is not a surprise to me that a Compression fitting which has a plastic ferrule failed.
Most plumbers have a certain preference when it comes to choosing a type of tubing, and today more plumbers are reverting to PEX. PEX tubing is the obvious choice when deciding between the two types of pipe. CPVC has been held accountable for many problems in common residential plumbing systems. CPVCâs incapability to withstand many of the trials that PEX tubing goes through has made PEX the giant of the two by a landslide. PEX is more sturdy, reliable, resistant, and nearly the same price, depending on the manufacturer of CPVC.
