“Over time the CPVC is getting brittle and cracking, and so i no longer use it,” he says. “Occasionally I have to use it with a repair if the system already has it inside, however i don’t use CPVC for repipes anymore.”
Grzetich is not really alone. Though still an accepted material for piping, CPVC is losing favor with a few plumbers as they encounter various issues with it while on-the-job. They claim it’s less a point of if issues will occur however, when.
“On some houses it lasts quite a long time before it gets brittle. Other houses, I do believe it offers more to do with temperature and placement of the pipe than anything,” Grzetich says. “But after a while, any type of CPVC will get brittle and eventually crack. And as soon as it cracks, it cracks excellent and then you’re going to get a steady flow of water from it. It’s unlike copper where you have a leak inside and it also just drips. Once CPVC cracks, it goes. I used to be at the house yesterday, where there were three leaks from the ceiling, all from CPVC. And when I attempted to correct them, the pipe just kept cracking.”
Sean Mayfield, a master plumber doing work for Water heater replacement Missouri City, Colorado, says in his work he encounters CPVC piping about twenty percent of the time.
“It’s approved to set in houses, nevertheless i think it’s too brittle,” he says. “If it’s coming out of the ground and you also kick it or anything, you do have a pretty good possibility of breaking it.”
He doesn’t apply it for repiping and prefers copper, partly due to the craftsmanship associated with installing copper pipe.
“I’m a 25-year plumber so I want to use copper. It genuinely has a craftsman to get it in,” he says. “Not everybody can sweat copper pipe making it look really good making it look right.”
But as being a more affordable substitute for copper that doesn’t carry a few of the problems related to CPVC, Mayfield, Grzetich as well as other plumbers say they frequently use PEX mainly because it allows more leeway for expansion and contraction, and also carries a longer warranty than CPVC. For Mayfield and Grzetich it’s the maximum amount of about the ease of installation since it is providing customers a product or service that is certainly less likely to cause issues in the long run.

“A large amount of it boils down to budget, yes, but in addition if you’re doing a repipe on a finished house where you need to cut the sheetrock and everything, it’s always easier just to get it done in PEX since you can fish it through like an electrical wire,” Mayfield says. “It cuts the labor down beyond doubt.
“And CPVC uses glue joints that put in place for some time,” he adds. “With the PEX, you simply cut it by using a plastic cutter, expand it by using a tool and set it over a fitting. It’s much less labor intensive so far as gluing and drilling holes. Gluing on CPVC, you have to glue every joint. Whereas PEX, you can probably run 30 or 40 feet of this through some holes so you don’t possess joints.”
Any piping product is going to be vunerable to problems if it’s not installed properly, but Mayfield notes that CPVC has a smaller margin for error than PEX because it is a much more rigid pipe that appears to get especially brittle over time.
“If a plumber uses CPVC and is also, say, off by half an inch on his or her holes, they’ll need to flex the pipe to have it inside a hole,” he says. “It will likely be fine for several years then suddenly, due to the strain, develop a crack or leak. Everything needs to be really precise about the measurements with CPVC. Then it’s additionally a little nerve-wracking to work on because through taking an angle stop that’s screwed onto CPVC and you’re using two wrenches, you usually flex the pipe a bit. You’re always worried about breaking the pipe because it’s brittle.”
“We did a home within a new subdivision – the home was just 6 years of age – and we needed to replumb the full house because it is in CPVC. We actually wound up doing three other jobs inside the same neighborhood. Afterward, the 1st repipe we did is at CPVC because we didn’t understand what else to make use of. But then we looked at it and located a greater product.”
“I’ve done about 20 repipes with Uponor. I’ve had zero callbacks, zero issues,” he says. “I utilize it over copper usually. The only time I use copper is perfect for stub-outs making it look nice. Copper continues to be a very good product. It’s just expensive.
“I do know plumbers who still use CPVC. Many people just stick to their old guns and whenever something like Uponor is released, they wait awhile before they begin making use of it.”
But in accordance with Steve Forbes of Priority Plumbing in Dallas, Oregon, CPVC can still be a dependable material for the plumbing system given that it’s installed properly.
In the blog on his company’s website, Forbes writes about a number of the concerns surrounding CPVC, noting that in the experience, CPVC pipe failures are based on improper installation and often affect only hot-water lines.
“CPVC will expand when heated, of course, if the device is installed that will not let the hot-water lines to freely move when expanded, this can result in a joint to fail,” he says. “Each instance We have observed was due to an improperly designed/installed system.”
Based on CPVC pipe manufacturer Lubrizol, CPVC will expand about an inch for each and every 50 feet of length when exposed to a 50-degree temperature increase. Offsets or loops are very important for too long runs of pipe in order to accommodate that expansion.
“I think that the trouble resides for the reason that many plumbers installed CPVC much like copper, and failed to permit a further expansion and contraction of CPVC systems,” Forbes says within his blog. “If the piping is installed … with plenty of modifications in direction and offsets, expansion and contraction is not a problem.”
Forbes does acknowledge that CPVC will get brittle, and extra care must be taken when attempting to repair it. Still, he stands behind the product.
“CPVC, if properly installed, is good and does not have to be replaced,” he says. “I repiped my own, personal house with CPVC over 10 years ago – no problems.”
Generally though, PEX is now the fabric associated with preference.
Within his Southern California service area, Paul Rockwell of Rocksteady Plumbing says CPVC plumbing is rare.
“Sometimes the truth is it in mobile homes or modular homes, nevertheless i can’t consider a foundation home that I’ve seen it in, inside the 15 years I’ve been working here,” he says. “I don’t know why it’s not around here. We used a variety of it doing tract homes in Colorado inside the 1990s after i was working there.”
Copper and PEX are what Rockwell most often encounters within his work. He typically uses Uponor PEX on repiping jobs.
“PEX is nice since you can snake it into places and you also don’t have to open several walls when you would with copper,” he says. “If somebody stumbled on me and wanted to conduct a copper repipe, I’d dexspky68 it but it could be 2 1/2 times the price of a PEX repipe just due to material and the additional time. So it’s pretty rare that somebody asks for your.”
In his limited experience working together with CPVC, Rockwell says he has seen the identical issues explained by others.
“The glue is likely to take an especially while to dry and I do mostly service work so the thought of repairing CPVC and waiting hours for your glue to dry isn’t very appealing,” he says. “And I’ve seen it get pretty brittle after a while. I don’t have plenty of exposure to it, but even though it were popular here, I believe I would still use PEX over CPVC. Given that it’s installed properly, I haven’t seen any troubles with it.”
