## Waste Disposal Units — Fitted Properly, Plumbed Neatly
A waste disposal unit (food waste disposer) bolts to the underside of your kitchen sink and grinds food scraps into a slurry that's washed away through the existing waste pipework. Fitted properly, they're transparent in daily use and significantly reduce kitchen bin trips.

Installation involves swapping the sink waste flange for a disposal-compatible mount, fitting the unit, reconfiguring the trap and waste run (often relocating the dishwasher connection), and either wiring to a switched fused spur or fitting an air switch through the worktop.

We also repair existing units — jammed grinding chambers, failed motor capacitors, leaking gaskets and damaged splash baffles — without immediately defaulting to full replacement.

## Real Work Examples

## Common Waste Disposal Problems
Most waste disposal complaints — leaks, smells, jamming, weak grinding — come down to poor original installation rather than faulty units. A leaking gasket, a misaligned mounting flange, or a waste pipe with the wrong fall will all cause trouble within months of fitting.

Leaks from the sink flange usually mean the original installer skipped the plumber's putty
- Smells from the unit usually mean the splash baffle is worn or the chamber needs cleaning
- Jammed units can almost always be freed with the supplied hex key — no need to scrap the unit
- Failed motors are usually a £25 capacitor, not a £200 replacement
- Wrong-spec units (continuous-feed vs batch-feed) cause ongoing frustration

## Our Process
1

### Survey
We check sink type, under-sink space, electrical supply, and waste pipe configuration before quoting.

2

### Supply or Fit
Quality units sourced at trade prices, or your supplied unit fitted — workmanship the same either way.

3

### Sink Adaptation
Existing waste flange removed, disposal-compatible mounting fitted with proper sealant, sink cleaned.

4

### Plumbing &amp; Wiring
Trap reconfigured, dishwasher feed re-routed if required, switched spur or air switch fitted (electrician partner for new circuits).

5

### Test &amp; Commission
Multiple flush cycles tested, leak-checked at every joint, operation demonstrated before sign-off.

## Why Choose Conroy

### All Major Brands
InSinkErator, Tweeny and other quality brands installed and repaired.

### Air-Switch Option
Worktop-mounted air switches available — neat, hidden electrics with no fused spur visible.

### Repair First
Jammed units, leaking gaskets and failed capacitors often repaired for a fraction of replacement cost.

### Proper Sink Mount
Mounting flange sealed correctly with plumber's putty — no slow leaks under the sink.

### Dishwasher Re-routing
Existing dishwasher waste connection re-routed through the disposal unit as standard, saving cupboard space.

### Workmanship Guarantee
All installation work carries a full guarantee on the work we've carried out.

## Technical Detail

### Continuous vs Batch Feed
Continuous-feed units run while water flows — fast and convenient. Batch-feed units only run when a cover is locked in place — safer in households with young children but slower in use. We'll recommend based on your usage.

### Power Ratings
Domestic units range from 0.5 to 1.0 horsepower. Higher HP grinds tougher waste (small bones, fruit pits, fibrous vegetables) and lasts longer. We typically recommend 0.75 HP minimum for a family kitchen.

### Air Switches
An air switch is a low-profile button on the worktop that controls the unit via a pneumatic line — no exposed switch on the wall, no fused spur in the cupboard. Adds about an hour to the install but looks far neater.

### Electrical Supply
Most units need a switched fused spur or air-switch wiring. We carry out the plumbing and air-switch fitting; new dedicated electrical circuits are arranged through our trusted local electrician partner.

### What Can and Can't Go In
Most food waste is fine. Avoid: bones (other than small chicken), fruit pits, large amounts of pasta or rice, fibrous vegetables (celery, corn husks), grease and oil. Manufacturer guidance varies — we'll walk you through your specific unit.
