A cable pokes a hole. Jetting cleans the whole pipe.
North County's oldest city has some of North County's oldest drains, and old drains have long memories. Every meal, every shower, every load of laundry since the houses went up left a little something behind on the pipe walls. So when your drain clogs and the snake clears it, the relief is real but usually temporary, because the snake only opened a tunnel through the buildup. Everything lining the pipe is still lining the pipe, and it closes back in the way soot closes in a chimney that only ever gets poked, never swept.
Hydro jetting is the sweep. A high pressure stream of water scours the whole inside of the line, wall to wall, end to end, and flushes the years of grease, soap, and scale out for good. What's left behind is about as close to new pipe as an old pipe can be, and that's why a jetted line stays quiet for years while a snaked line keeps calling you back every few months like clockwork.
Should every clog get jetted? No, and we'd rather tell you that than sell you something. Plenty of clogs are one time problems that a snake handles completely. The technician looks at your actual situation, explains it in plain English, and gives his honest read. Then it's your call, and only yours.
"Scale and grease coat the pipe. Jetting takes it back to clean."
