A snake pokes a hole. Jetting cleans the whole pipe.
Island drains work harder than most people realize. Between the historic cottages with their original lines and the kitchens that never stop cooking, a Coronado drain has usually been collecting grease, soap, and buildup for a very long time. So when it clogs and the snake clears it, here's what really happened. A hole got punched through the blockage. The coating on the pipe walls, all those years of it, stayed put, and it starts closing the hole again the day the plumber leaves.
Hydro jetting takes the opposite approach. Instead of tunneling through the buildup, a high pressure stream of water washes the pipe walls down completely, the way you'd wash a greasy pan instead of just scraping a channel through the middle of it. When the jetter's done, the line is genuinely clean inside, about as close to new as old pipe gets, and the recurring clog stops recurring because the thing rebuilding it is gone.
Is it always necessary? No, and on an island where word travels one bridge at a time, we wouldn't dare oversell it. Some clogs need nothing more than a snake. The technician looks at what your line is actually doing, tells you straight, and recommends what fits. You decide from there. Every time.
