Agreed. I’m all for people doing their own work on their own property but it’s flat out irresponsible to endorse something with such confidence when you haven’t done but maybe a couple hundred fittings in your life. Sure someone will be along shortly to say their house was piped exclusively with SB fittings and they haven’t had a leak in 15 years. That’s great, and they probably will never have a leak. Problem is, that’s a tiny sample, when they fail it’s usually catastrophic, they do have a higher fail rate than other fittings, and it’s never the least expensive or best fitting to use. A sharkbite is a fitting to use as a patch when the installer doesn’t have the time or experience to make a proper joint.
Chernobyl comes to mind.
They will always fail. It’s just a matter of time. They rely on O rings to seal and they eventually oxidize and crack. One side is well exposed to the atmosphere. Things like proximity to electric motors that are present in many utility rooms will be exposed to more ozone than standard and hasten the rubbers demise.
I still can't understand why cpvc exists. I only ever ran into it in trailers.
Save bundles? They are crazy expensive vs copper fittings or pex
Sure, if you use M pipe(which is against the law in many places to use with domestic water) with acidic water, otherwise proper L pipe last 60 plus years. Hell my grandfathers house had copper **** pipe that was really light weight, and the first piece failed last year. Build in 69' And the section that failed was installed level without any run to it.
you're talking DWV I assume
Yes, that would be **** pipe, much thinner wall than pressure pipe and contents more corrosive.
just out of curiosity... what is you house pressure coming in ? are you regulated pressure whole house? true the shark bites are for quick fix only, but seen them only fail when the main line pressure goes sky high over night, seen day time pressurize @ 55 to 60 lb,
I always deburr, I use sharkbites all the time to pressure test systems (cap stub outs). Its a great application for them.
Even though it’s rated for 140*, you shouldn’t pipe hot water with PVC, CPVC is good up to 200*. At 73* they have the same pressure rating, as temps go up CPVC maintains a higher rating. CPVC gets a bad rap but it’s not entirely justified (IME). The larger sizes (2” and up) are a cost effective option to copper where allowed. I’m not crazy about it in residential but I did use it to do the overhead in my garage for the room over it. The pipe in the walls above is all copper. It’s easily accessible, won’t hurt anything if it fails, and I already had it.
If by fail you mean drip, I sort of agree. If by fail you mean blow out, then no, that's 100% installation error.
Drip and a spray stream. Either way in a wall it can cause 10’s of thousands of dollars in damage.
