Hydro jetting

Jetting pressure and nozzle choice depend on pipe material and condition — clay and older cast iron need a careful approach.

What this covers

High-pressure water jetting to clear grease, scale, silt and roots from drain and sewer lines.

Do this first

• Keep clear of sewage and electrics near standing water.
• Avoid pouring more water into a clogged fixture.
• Note whether multiple fixtures are affected and photograph any backup if safe.
