InSinkErator Replacement & Installation London

InSinkErator repair and common faults

Most calls fall into a handful of faults and nearly all of them are repairable. A unit that hums but is not spinning has jammed on bone, a peach stone or cutlery; we free the grind plate, clear the obstruction and reset the overload. A unit that will not turn on at all is usually a tripped reset button, a failed air switch or a dead switched spur rather than a burnt-out motor. Slow draining points at a blockage in the discharge tube or trap, and a leak from the bottom of the unit means the internal seal has failed.

• InSinkErator not working, won't turn on or reset not working
• Humming but not spinning, jammed or blocked grind chamber
• Leaking from the bottom or leaking under the sink
• Slow draining, backing up or noisy operation
• Air switch repair and switch replacement
• Motor repair, bearing noise and overload faults

Waste disposal unit installation

The unit is mounted to the sink with a new flange and seal, the trap arrangement is reconfigured because a food waste disposal unit needs different waste geometry, and any dishwasher discharge is connected to the correct inlet. Electrically, we install a switched fused spur or an air switch positioned so it can be reached without leaning over the sink. Everything is run and leak-checked under load before we leave. We also handle kitchen waste disposal installs as part of a new sink or worktop fit.

• New sink flange and mounting seal fitted
• Waste and trap reconfigured for the unit
• Dishwasher discharge connected to the correct inlet
• Switched spur or air switch installed and tested

Choosing the right food waste disposal unit

Motor power and grind stages decide how well a unit copes. A small household producing soft vegetable waste is fine with an entry-level model, but a busy family kitchen or a restaurant prep area needs a higher horsepower multi-stage unit that will not jam on bones and fibrous waste. Continuous feed units are more convenient; batch feed units are safer in households with young children. We size the unit to how the kitchen is actually used rather than selling the biggest model in the catalogue.

Servicing and maintenance

An annual service keeps a disposal unit quiet and stops the jams that eventually kill the motor. We flush and descale the grind chamber, check the splash guard and flange seal, inspect the discharge tube and trap for build-up, test the overload and the switch, and tighten the mounting assembly. In restaurants and canteens we schedule visits alongside grease-trap servicing so the whole kitchen waste run stays clear.

Replacement and replacement cost

Replacement makes sense once the body itself is leaking, the motor has burnt out, or the unit is more than ten years old and jamming repeatedly. Cost depends on the model, whether the existing electrical supply and switch can be reused, and whether the waste pipework needs altering for a taller unit. We quote a fixed price covering the new waste disposal unit, removal and disposal of the old one, installation and testing before any work starts.

• Like-for-like swaps completed in a single visit
• Existing spur or air switch reused where it is safe to do so
• Old unit removed and recycled
• Fixed written quote before work begins

Removal, sink installation and commercial kitchens

Not everyone wants to keep a disposer. We remove redundant units, restore a standard basket strainer and re-pipe the trap so the sink drains properly again, which is common during a kitchen refit or a new sink installation. In catering environments a disposal unit cuts the waste going into bins and grease traps, but it must be specified for the duty and installed alongside proper grease management. We install commercial-grade units, keep them on a maintenance schedule, and coordinate with drain jetting downstream.

Emergency same-day repair

A leaking or dead disposal unit in a working kitchen is not something to book in for next week. We hold same-day slots across London and the M25, with 24/7 cover for restaurants, pubs and canteens where a sink out of service closes the prep area. Call 0208 935 5572 and we will confirm an arrival window and a diagnosis charge before dispatch.
