High-pressure water jetting

Jetting pressure is matched to the pipe material — older clay needs a careful approach.

What this covers

Jetting to clear fat, scale, silt and roots from drains and sewers.

Do this first

• Keep clear of sewage and electrics near standing water.
• Avoid pouring more water into a blocked fitting.
• Note whether upstairs and downstairs drains are affected and photograph any overflow if safe.
