Drain cleaning & sewer clearing in Utah

In many older Utah homes built before the 1970s, the sewer lateral is vitrified clay or cast iron, whose joints loosen under freeze-thaw ground movement and let tree roots in, where they snag waste and form blockages. Mechanical snaking cuts roots for short-term relief, but hydro jetting scours the pipe wall more completely and a follow-up camera inspection shows whether the line is cracked, offset, or holding a low spot. If recurring backups continue, replacing or lining the lateral is the durable fix, since roots return through the same compromised joints. Fixtures on floors below the upstream public-sewer manhole elevation should be protected by a backwater valve per the state plumbing code.

Across Utah, drain and sewer work is governed by these statewide rules under the state plumbing code:

• Permit

  Clearing an existing drain by snaking or jetting generally needs no permit, but repairing or replacing buried sewer/building-drain pipe is regulated plumbing work that requires a building/plumbing permit from the local authority having jurisdiction.

  Repair/replace only
• Cleanout access

  Under the Utah State Plumbing Code (IPC-based), the building drain/building sewer junction must have a cleanout at or within 10 feet upstream of the junction; building sewers under 8 inches need cleanouts at intervals not exceeding 100 feet, plus a cleanout at any horizontal change of direction greater than 45 degrees.

  Required
• Licensed contractor

  Plumbing and sewer work must be performed by a licensed plumber (journeyman, master, or licensed contractor); licensing is administered by the Utah Department of Commerce, Division of Professional Licensing (DOPL).

• Lateral ownership

  In Utah the homeowner generally owns and maintains the sewer lateral from the house to its connection at the public main, with the municipality responsible only for the main itself.

  Homeowner to the main
• Backwater valve

  Utah State Plumbing Code Section 715 requires fixtures on a floor below the elevation of the next upstream public-sewer manhole cover to discharge through a backwater valve (compliant with ASME A112.14.1 or CSA B181.1/B181.2) installed with access to its working parts; fixtures above that elevation may not discharge through one.
