Here are the common signs your waste disposal needs repair or replacement.
The most common problem. Usually a bone, fruit pit, or hard object stuck between the grinding plate and shred ring. The motor hums but nothing moves. We clear jams same-visit — if the motor has burned out, we'll quote a replacement on the spot.
Water dripping from the bottom or sides of the unit. Usually a failed sink flange seal, a loose dishwasher connection, or a cracked waste outlet. Flange seals can be replaced — if the body is cracked or corroded, replacement is the better option.
The motor runs but the grinding plate won't turn. Could be a jam, a seized bearing, or a failing motor. If the reset button doesn't fix it and the jam is cleared but it still won't spin, the motor is likely gone.
No hum, no vibration, nothing. Check the reset button on the bottom of the unit first — it's a built-in overload switch. If that doesn't bring it back, the issue is electrical (switch, wiring, or the motor itself). We diagnose and fix it.
Persistent odour even after cleaning with ice and citrus. Usually means food residue is trapped in the grinding chamber or there's a blockage in the waste line downstream. We clear the unit and the drain to eliminate the source.
Water pools in the sink when the disposal runs. The unit might be grinding poorly (worn grinding plate), or the waste line downstream is partially blocked. We diagnose whether it's the unit or the drain — and fix both. Drain unblocking Auckland →
Jammed, leaking, or dead — we fix it. Need a new one? We install and replace all brands.
Jammed units, leaking seals, faulty switches, humming motors, and slow drainage. We diagnose the problem and repair it same-visit. We carry common parts and seal kits on the truck — most repairs are completed in under an hour.
Old unit beyond repair? We remove the old unit, install a new one in the same sink cutout, connect the plumbing and dishwasher drain, and test. We carry common Insinkerator models on the truck for same-day replacement — no waiting for parts.
No disposal unit yet? We install new waste disposal units into existing sinks — modify the sink waste, connect the drain, set up the dishwasher connection if needed, and ensure the electrical supply is safe. Full installation from scratch.

We also install and service Franke and other waste disposal brands available in NZ. If your model isn't listed here, call us — we've worked on virtually every unit sold in New Zealand.
A repair is cheaper — but sometimes a new unit is the smarter move.
The unit is less than 8 years old and the problem is a jam, a leaking flange seal, a faulty switch, or a tripped reset button.
The motor still runs and the grinding plate still turns — the issue is mechanical, not the motor itself.
It's a quality unit (Insinkerator Evolution or similar) worth maintaining rather than replacing with a cheaper model.
The motor has burned out — humming but not turning even after clearing the jam. Motor replacement costs more than a new unit.
The unit is more than 10 years old and experiencing frequent jams, poor grinding, or persistent leaks from the body.
The body is cracked or corroded — no seal replacement will fix a cracked housing.
You want to upgrade to a quieter, more powerful model.
Most jams and blockages are caused by putting the wrong things down the unit. Here's a quick guide.
Soft food scraps, fruit and vegetable peelings (not fibrous), small chicken bones, egg shells, citrus peel (great for cleaning), ice cubes (helps clean the grinding plate), and most cooked food waste in small amounts.
Large bones, fibrous vegetables (celery, corn husks, artichoke), coffee grounds in large quantities, cooking oil or grease, pasta and rice in large amounts, fruit pits, seafood shells, and any non-food items. These jam the unit, block the drain, or cause premature wear.

Waste disposal unit installation in Auckland starts from around $227 including the unit, installation, and testing for a straightforward replacement where the plumbing is already set up. New installations requiring sink modification, waste connection, or electrical work start from around $450 plus the cost of the unit. More powerful units or complex installs cost more. We provide upfront fixed-price quotes — $0 call out fee.
Yes. A jammed waste disposal is the most common repair we see. Usually caused by a bone, fruit pit, or hard object lodged between the grinding plate and the shred ring. We can usually clear the jam and get the unit running again same-visit.
Waste disposal leaks usually come from one of three places: the sink flange seal at the top, the dishwasher inlet connection on the side, or the waste outlet at the bottom. Flange seals deteriorate over time and can be replaced. If the unit body is cracked or corroded, replacement is the better option.
A quality waste disposal unit typically lasts 8 to 15 years with normal residential use. Cheaper units may fail within 3 to 5 years. Lifespan depends on build quality, motor size, how often the unit is used, maintenance, and whether inappropriate items are put down it. Signs your unit is reaching end of life include frequent jams, poor grinding, persistent odours, leaking from the body, and the motor humming but not spinning.
We install and repair all major waste disposal brands including Insinkerator, Fisher & Paykel, Scrapeater, and Franke. Common Insinkerator models we work with include the Model 46, Model 56, E20, Standard 460, Premium 550 SR, Evolution, and Evolution Plus 1000 SR. We also install Fisher & Paykel and Scrapeater units. We carry common models and parts on the truck for same-day replacements.
Yes. We can replace your existing unit with any compatible brand or upgrade to a larger, more powerful model. The plumbing connections are usually the same — it's a straightforward swap.
Yes. Waste disposal installation involves plumbing connections to your sink waste and potentially your dishwasher drain. Incorrect installation can cause leaks, drainage problems, and damage to your sink. A licensed plumber ensures the unit is correctly connected, sealed, and draining properly.
Bad odours usually mean food residue is trapped inside the grinding chamber. Running cold water while operating the unit, grinding ice cubes and citrus peel, and avoiding fibrous foods all help. If the smell persists, there may be a blockage downstream — we can clear that for you.
We cover all of greater Auckland — North Shore, West Auckland, Auckland Central, East Auckland and South Auckland. With plumbers across Auckland, most callouts are reached in under 30 minutes.
Waste disposal installation involves electrical and plumbing connections that in New Zealand must be carried out by registered tradespeople to comply with building code. Incorrect installation can cause leaks, electrical hazards, and void manufacturer warranties. We recommend always using a certified plumber.
What goes in: soft food scraps, fruit and vegetable peelings, small bones, eggshells in moderation, citrus peels, and small soft food waste. What to avoid: large bones, fibrous vegetables (celery, corn husks, artichoke leaves), starchy foods in large quantities (potato peels, pasta, rice), fruit pits and stone-fruit seeds, cooking oil and grease, large amounts of coffee grounds, seafood shells, and anything non-food. Always run cold water before, during, and after using the unit.
Most waste disposal problems fall into a few categories: the unit is jammed (often fixable by pressing the reset button underneath), it's humming but not turning (something stuck in the grinding chamber), it's leaking (a seal failure or pipe issue), or it's completely dead (electrical or motor failure). We diagnose and repair all of these.
Properly used waste disposal units don't damage drains. Problems usually arise from misuse — putting in fibrous food, grease, or too much material at once. If you have an older drainage system with existing issues, a waste disposal can accelerate blockages. We can inspect your drains first if you're unsure.
Response Plumbing is Auckland's go-to for waste disposal unit repairs, replacements, and new installations. Whether your Insinkerator is jammed solid, leaking from the flange, humming but not grinding, or completely dead — we diagnose and fix it same-visit. If the unit is beyond repair, we carry common Insinkerator models on the truck and can replace it the same day. No waiting for parts, no second visit.
We install and service all major waste disposal brands — Insinkerator, Fisher & Paykel, Scrapeater, Franke, and other brands available in New Zealand. Insinkerator is the most common brand we work with and we know these units inside out. From the compact Insinkerator Model 46 and the popular Model 56, to the E20, Standard 460, Premium 550 SR, Evolution, and the top-of-the-range Evolution Plus 1000 SR — we've repaired, replaced, and installed thousands of them across Auckland homes. We also install Fisher & Paykel units (popular in new builds) and the affordable Scrapeater range. We carry common models in stock and can supply any model in the range — you don't need to source your own unit. One call, one quote, one invoice.
A waste disposal unit is connected to your sink waste, your dishwasher drain, and your kitchen drainage — it's plumbing, not just an appliance. That's why it needs a licensed plumber, not a handyman. We ensure the unit is correctly mounted, sealed, connected to the waste line, and draining freely. If the slow drainage is actually a blocked drain downstream rather than the disposal unit itself, we'll find it and clear it. Need a new kitchen tap while we're under the sink? We handle that too.
We work across all of greater Auckland — residential and commercial properties. Need an emergency plumber in Auckland? We're available 24/7. Every waste disposal repair and installation is backed by our 5-year workmanship warranty and $5 million public liability insurance. Call 0800 877 586 for a free quote.
