Kitchen Plumber Central Coast

Why Central Coast Homeowners Trust Dylan With Their Kitchen

Dylan Attard is a fully licenced plumber (NSW Licence No. 457032C) and a Master Plumbers Association accredited member, based in Berkeley Vale. When you book a kitchen job with TrueFlow Plumbing and Drains, you are dealing directly with the person doing the work, not a call centre or a subcontractor. That is why 65% of our jobs come through word of mouth.

Kitchen work happens in the busiest room in your house, usually surrounded by new cabinetry, stone benchtops and appliances you have just paid for. Every job is fully insured, every fitting is compliant with AS/NZS 3500, and every visit finishes with a leak test and a clean-up. If something is not right afterwards, our Lifetime Labour Guarantee covers it.

Kitchen Plumbing Problems We Fix

Most kitchen callouts come down to a handful of recurring faults. Here is what we see most often on the Central Coast and what usually causes it.

A dripping or leaking kitchen mixer tap

A worn ceramic cartridge is the usual culprit on a modern mixer tap, and a perished O-ring is the usual culprit where the spout swivels. Both are inexpensive spare parts, but the fault rarely fixes itself and a slow drip can add hundreds to your annual water bill. If your tap has already been reseated and still drips, the cartridge or the tap body is the problem, not the washer. We repair where a repair will hold and replace where it will not. See our leaking tap repairs page for the full breakdown.

Water pooling in the cupboard under the sink

Damp chipboard, a musty smell or a warped cupboard base almost always points to one of three sources, a failed flexible hose connection, a loose P-trap, or a leaking waste outlet under the sink bowl. Flexible braided hoses have a service life of around ten years and are the single most common cause of kitchen water damage in Australian homes. If you cannot see where the water is coming from, we can trace it without pulling your kitchen apart as part of our water leak detection service.

A blocked or slow-draining kitchen sink

Kitchen blockages are usually fat, oil and grease that has cooled and hardened inside the waste pipe, often mixed with coffee grounds and food scraps. Boiling water and supermarket drain cleaners shift the surface of it and leave the rest behind, which is why the sink slows down again a fortnight later. We offer blocked drains services whereby we clear kitchen lines properly with a drain machine or high pressure water jetting, and use a CCTV drain camera when a line keeps blocking so you find out why.

A smell coming from the kitchen drain

A sour or sewer-like smell at the sink normally means either a build-up of decaying food waste in the waste pipe, or a dry or damaged trap letting sewer gas back into the room. A gurgling noise alongside the smell points to a venting problem rather than a blockage. Neither is something to live with, and both are quick to diagnose.

Poor water pressure at the kitchen tap only

If pressure is fine everywhere else in the house but weak at the kitchen sink, the aerator on the spout is usually clogged with sediment or scale, or the isolation valve under the sink has partially closed. Where the whole house is affected, the cause sits further upstream in the mains or the pressure limiting valve.

A dishwasher that will not fill, will not drain, or leaks

Dishwasher faults split cleanly into appliance faults and plumbing faults. If the machine will not fill, the inlet valve or the tap connection is usually at fault. If it will not drain, the waste connection or the kitchen line is usually blocked. If water appears on the floor after a cycle, the drain hose connection is the first thing to check. We handle the plumbing side and will tell you honestly when the problem is the appliance itself and you need an appliance technician instead.

Kitchen Plumbing Services We Provide

Kitchen tap and mixer replacement

We supply and install kitchen mixers, pull-out spray taps, swan neck mixers and traditional pillar taps. A straight swap on an existing single-hole benchtop usually takes under an hour, including isolating the water, removing the old flexible hoses, fitting the new tap with a fresh gasket, and pressure testing for leaks. Where you are moving from twin taps to a single mixer, the benchtop or sink may need a new hole cut, which we will confirm before quoting. If you would rather attempt it yourself, our guide on how to change a kitchen mixer tap walks through the process.

Kitchen sink installation and replacement

Undermount, drop-in and farmhouse sinks all connect differently, and the waste configuration changes with single bowl, double bowl and bowl-and-a-half designs. We install new sinks into existing benchtops, replace failed or corroded sinks, and reconnect the waste, trap and tap during a renovation fit-off. Undermount sinks in stone benchtops need the benchtop fabricator to cut and mount the sink first, and we work around whatever your stonemason has set.

Dishwasher installation

We install new dishwashers, reconnect after a renovation, and add a dishwasher point to a kitchen that has never had one. That means a dedicated cold water connection with its own isolation valve, a properly secured drain hose with an anti-siphon loop, and a leak test before we leave. Adding a dishwasher point where none exists requires running a new water line and a waste connection into the cabinet, which is a larger job than a straight swap. Where the dishwasher also needs power, we will coordinate with your electrician so both trades are not tripping over each other.

Waste disposal unit installation

InSinkErator and similar waste disposal units mount to the sink waste and need a matched flange, a modified trap and a power point under the sink. Existing plumbing rarely takes one without modification. We install new units, replace failed ones, and reinstate standard waste plumbing where a unit is being removed.

Filtered and boiling water tap installation

Under-sink filter systems, instant boiling taps, chilled water taps and combination units all need a cold water take-off, a mounting hole in the benchtop and, in most cases, a power point in the cabinet. Filtered water taps are one of our most requested kitchen upgrades on the Central Coast, largely because of the chlorine taste in treated mains water.

Fridge water line for ice makers and chilled water

Plumbed fridges need a dedicated cold water line run to the fridge cavity, usually with an isolation valve so the fridge can be pulled out without shutting off the kitchen. We run new lines during renovations and retrofit them into existing kitchens. The same applies to plumbed coffee machines.

Gas cooktop connection

Connecting or relocating a gas cooktop is licenced gasfitting work, not general plumbing. Dylan holds the relevant NSW gasfitting authorisation and can connect new cooktops, install a gas point where none exists, and test for leaks on completion.

Kitchen Renovation Plumbing, What’s Involved

A kitchen renovation involves two separate plumbing visits, and knowing that upfront makes your build schedule far easier to plan.

The rough-in happens once the old kitchen is stripped out and before the plasterer and cabinet maker start. This is where water supply lines and waste pipes are relocated to suit the new layout, capped and pressure tested. If you are moving the sink to an island bench or to the other side of the room, this is the stage where the waste line gets set at the correct fall, which is the part that decides whether your new sink drains properly for the next twenty years. Get the fall wrong at rough-in and no amount of work at fit-off will fix it.

The fit-off happens after the cabinetry is installed and the benchtop is in. Sink, tap, dishwasher, filter tap, waste disposal and fridge line all get connected, tested and commissioned. This is normally a half day for a standard kitchen.

Relocating the sink is the single biggest variable in what a kitchen renovation costs to plumb. Keeping it on the same wall is straightforward. Moving it to an island in a slab-on-ground home means cutting the slab to run new waste, which is a substantially larger job. If you are still at the design stage, a five minute phone call before the plans are locked in can save you thousands.

All work is carried out to AS/NZS 3500 and you will receive a Certificate of Compliance on completion, which is the document you will need if you sell the property or make an insurance claim.

What Happens When You Call

  1. Phone consultation. Dylan will ask what the kitchen is doing, what appliances are involved, and whether it is a repair, a replacement or a renovation. Photos help, and you can send them straight through.
  2. Upfront quote. You get a clear per-job price before any work starts. No hourly rate, no hidden costs.
  3. Same day or scheduled booking. Repairs and straight swaps are usually same day. Renovation rough-ins and fit-offs are booked around your builder’s schedule.
  4. The work. Dylan isolates the water, completes the job, pressure tests every connection, checks the drainage under load and cleans up the cabinet before he leaves.
  5. Lifetime Labour Guarantee. If anything goes wrong with our workmanship, we come back and fix it at no charge.

Four Habits That Prevent Most Kitchen Callouts

Never pour fat, oil or grease down the sink.

It cools in the pipe and sets. Wipe pans out with paper towel and bin it.

Bin coffee grounds and rice.

Both swell and bind with grease to form the blockages that need a drain machine to shift.

Check your flexible hoses once a year.

Open the cupboard, look for rust spots, bulges or green corrosion on the braiding, and replace them at around ten years regardless of appearance.

Run hot water for thirty seconds after washing up.

It carries residual grease past the trap instead of leaving it to set at the first bend.

Kitchen Plumbing Frequently Asked Questions

Do I need a licenced plumber to install a kitchen tap in NSW?

Yes. Any work that connects to your drinking water supply or sanitary drainage must be carried out by a licenced plumber under the NSW Plumbing and Drainage Act. That includes tap replacement, sink installation, dishwasher connection and waste disposal units. Dylan holds NSW Licence No. 457032C and is Master Plumbers Association accredited.

How long does it take to replace a kitchen mixer tap?

A straight replacement into an existing single hole usually takes 45 to 60 minutes, including isolating the water, removing the old tap and hoses, fitting the new tap and leak testing. Allow longer where the old tap is corroded in place, where the benchtop needs a new hole, or where the isolation valves under the sink have seized and need replacing at the same time.

Can you move my kitchen sink to an island bench?

Usually yes, but it depends on your floor construction. In a home with a suspended timber floor, running a new waste line under the floor is straightforward. In a slab-on-ground home the slab needs to be cut and made good, which is a considerably bigger job. We will confirm which applies to your home before quoting, and it is worth asking before your kitchen design is finalised.

Do you supply the tap and sink, or should I buy my own?

Either works. We can supply quality fixtures from brands we know hold up, or install what you have already bought. If you are supplying your own, buy a WELS-rated product from a reputable supplier. Very cheap imported taps often use non-standard cartridges, which means that in three years’ time no spare part is available and the whole tap has to be replaced.

Why does my kitchen sink keep blocking even after I clear it?

Repeat blockages in the same kitchen line usually mean fat and grease has built a hard layer along the inside wall of the pipe, narrowing it permanently. Plunging or a supermarket drain cleaner reopens a channel through the middle but leaves the build-up behind, so it closes again. High pressure water jetting strips the pipe wall back to full diameter. If it still blocks after that, a CCTV camera inspection will show whether there is a fall problem, a partial collapse or tree root intrusion further down the line.
