SIX7 Plumbing Waste Disposal Installation Colombo
The Wellawatte meat-in-sink habit ends with a grinder under the counter. We fit under-sink disposals in homes and commercial grinders in kitchens — mounted, sealed, load-tested.
The Colombo kitchen has two waste problems that a disposal solves: the habit of putting meat, bones and scraps down the sink drain (which no drain was built to take), and the hygiene problem of food waste sitting in an open bin. A disposal under the sink takes the waste straight to the drain line, ground fine enough to flow. For homes, it's a one-unit fit; for commercial kitchens, it's a larger grinder sized to the menu volume.
Mounting, seal and drain alignment are where installs fail later. Poor mounting leaks at the ring; wrong discharge slope jams at the bend. We mount to spec, align the discharge, coordinate the switch or socket (new circuits via a licensed partner), and load-test with real waste before we leave. If you already own the unit, we fit it labor-only after inspection — and we refuse to fit one we know will fail.

Quote
The quote covers the unit, the mounting ring and the dishwasher tee - one price, no add-ons later.
Repair
We fit the mounting assembly, seal the flange and wire the switch to code.
Verify
We run it under load with water and ice, then check the seal dry with the unit running.
"Every installation is load-tested before we leave — run, drain, silent — and sealed so the cabinet underneath stays dry."

Extend the Life of Your System
Prevention
- •Never put fibrous food waste (celery, corn husks, onion skins) down a disposal. They jam the impellers.
- •Run cold water when using the disposal. It solidifies grease so the impellers can chop it instead of smearing it.
When To Call Us
- •A leaking disposal under your sink is damaging your cabinet. Water damage spreads fast and is expensive to repair.
- •A disposal is only as good as its mount — flange, gasket and dishwasher tee sealed as one, tested under load before you run it.
