Hydro Jetting in Tustin

On modern plastic, yes, and usually unnecessary. On old clay it is both the right tool and the real risk: it is what actually removes roots, and it is also what finishes off a joint that has already opened. That is why nothing old is jetted here before it has been seen inside.

Where grease was the cause, years, because it starts from a clean wall rather than a hole through the deposit. Where roots were the cause, an interval rather than a fix — they return through the same joint, and the honest question is whether that interval is worth more than repairing the joint once.

It is the part of plumbing concerned with the pipes that carry waste away, rather than the pipes that bring water in — and in California it is not a separate trade. Drainage, sewer and storm drains sit inside the same C-36 plumbing classification as everything else. What makes it distinct in practice is the equipment rather than the license: a drum auger for traps and branches, a larger machine with a cutting head for main lines, a jetter for grease and roots, and a camera that clears nothing but decides which of the other three is right. A business describing itself as a drain company has usually specialised in those tools, not qualified differently.

In Tustin, that depends on your address more than it does in almost any city in Orange County — because this one holds about 140 years of plumbing inside its limits. The historic buildings on Main Street and El Camino Real date to the 1880s; Tustin Legacy has been building since 2003 on the 1,153 acres of a Marine air station that closed in 1999. An original clay lateral is jointed every few feet and open to roots at every one of them: it benefits from attention and eventually wants replacing. Modern plastic has sealed joints, does not scale and does not corrode: there is nothing accumulating in it between blockages, so scheduled cleaning removes nothing. Same question, same city, opposite answers.
