If you’re running a metal waterline through a concrete slab make sure it is sleeved!

If you’re running a metal waterline through a concrete slab without a sleeve, congratulations—you may have just installed a future indoor water feature! 😂💦


Metal pipe and concrete rubbing shoulders for the next 30 years isn’t exactly a Hallmark love story. Moisture, chemicals in the concrete, and corrosion can eventually attack that pipe until one day it decides, “I’ve had enough. I’m BUSTING!” 💥


And don’t worry—it won’t leak when it’s convenient. Plumbing has standards! It’ll wait until Sunday morning, Christmas Eve, the LSU game, or 10 minutes after you leave for vacation. 😂


Then somebody asks, “Why did this pipe fail?”


Well… because apparently the 50-cent sleeve was too extravagant for the construction budget! 🤦‍♂️


Sleeving a metal waterline where it penetrates concrete helps isolate and protect the pipe from corrosive conditions. It’s cheap, simple, and considerably easier than explaining why water is bubbling out of your slab like Old Faithful.


So remember:


SLEEVE THE PIPE NOW… OR PAY THE PLUMBER LATER! 🔧💰😂

Why does the main drain line have a s-trap? A toilet already has a built-in trap.
