Can't the certifications also be faked?? John

If you're talking about superior durability, I would say yes - PEX is more durable than CPVC. CPVC is well known for embrittlement as it approaches 10 years and worse, particularly for hot water pipes. John

I have no experience with them, but there are enzymatic drain cleaners sold which are supposed to be completely harmless to pipes. John

Nope, battery powered "250psi" pump, but i do have an accurate gauge. John

Yes to 'I can check/adjust air with the system only depressurized" or yes to 'I must drain the tank of all water from the manifold". "Daylight" might be above the manifold" - I'll have to see where the heights are. The house is in my wife's, BIL's, and SIL's names after their father died, and...

My brother in law's well pump is short cycling (5 seconds) when he runs any water. His 20 gallon Amtrol tank is 15 years old so I know it's reaching the end of its life, but I thought I would try to adjust the air pressure before replacing it because it's in a crawl space. Can I just shut the...

I can't answer your question but that is disturbing to hear. John

Why is this even being debated?? The mighty Ferguson is the only answer - the "King of Bowls".

While in Home Depot today, I passed through the plumbing dept. and noticed some Apollo brand PEX A along with some expansion fittings and T's. Oddly, there were two types of Apollo brand PEX A - a translucent white pipe that looked and felt like Uponor and a solid white pipe that looked like PEX...

That's *exactly* what I would do... John

It's hard to say what went wrong without being there, but other than scrupulous cleaning of the pipe and valve and using quality flux and solder, my best guess is that it's a heat issue - as in not enough. The valve body is a big heat sink, and where it's pretty easy to solder a pipe into a low...

Thanks John, after reading your warning I looked up that valve, and you probably saved me from (at minimum) twisting the tubes or worse. I'll heat the bonnet thoroughly before rotating. John

Like a copy of the Delta - will Delta parts fit it? Thanks for info on the Moen, I'll pick up a cartridge for him next week. Strange that the house was built in 1993 and it seems the builder used two different valves? It's possible the main bath was replaced but I won't be able to check until...

My son has a problem with a stiff shower valve, and he sent me a pic. It's made by Comco which I've never heard of. Are these any good? A generic version of a different brand? There's no direct access behind the shower so I'm not thrilled about the prospect of replacing the whole valve...

Even if properly pressed, I see 14 O-Rings holding back the pressure in a one foot square area.. I wonder if they found that with a stethoscope? What a shame. John

Regarding the Bites in confined (inaccessible) spaces, I confess I would never use one there, but they *are* code allowed in most places. AFAIK, the only way they fail is when not installed properly, and that means making sure the pipe is deburred and smoothed. If you sanded, that's fine as...

I'm convinced Integrity is using an AI response.

I agree it's like riding a bike, but some people were never very good at riding bikes or sweating pipes. For the latter, the propress is a great tool. I'm not against tools - for PEX I bought a powered expansion tool and heads, but those are necessary to make (what I consider) the best PEX...

"In my opinion it is much faster to cut and propress again than it is to unsweat a fitting, clean it, prep to solder and start over." I guess that depends on how good you are at sweating. A redo with propress also means cutting, remeasuring, and replacing a section or more of pipe - plus...

Certainly provide the bad section as they require, but if it's a larger section that was removed, I would keep a part of it in case the sample you send them gets "lost". If they allow a repipe claim, I would see if I could settle with Uponor for a payment settlement instead and have someone...
