A snake pokes a hole. A jetter cleans the pipe.
Beach town drains have their own story. The older cottages near the pier have been collecting decades of everything, and when a drain out here clogs, gets snaked, and clogs again a few months later, that's not bad luck. The snake did its one job, it opened a hole through the blockage. But the grease, soap, and buildup coating the pipe walls stayed behind, and it closes the hole back up the way the tide fills in a hole dug at the waterline. Give it time, it's like nothing happened.
Hydro jetting actually clears the line. A high pressure stream of water scrubs the pipe walls the whole way down, stripping years of buildup off instead of drilling through it, and flushing it all out of the system. When it's done, the inside of the pipe is about as close to new as old pipe gets. The drain that kept slowing down every few months just stops doing it, because the material that kept choking it is gone.
Does every clog need jetting? No, and you'll hear that from us when it's true. Plenty of backups are one time events a snake handles fine. The technician evaluates your actual line, explains what he sees in plain English, and gives his honest recommendation. The decision is yours, start to finish.
