Plumbing & gas fitting for Auckland — done properly.
From burst pipes at 3am to gas certifications, bathroom renovations and the dripping tap that's driving you mad — here's what BMP (Benchmarc Plumbing & Gas Ltd) does. Pick the closest fit, or call 0274 267 267 and we'll work it out together.
24/7 emergency plumbing
Pipes don't burst at convenient times. The toilet doesn't overflow during business hours. When something goes wrong with your plumbing, you need someone on the line — not a call centre that takes a message.
BMP is owner-operated and always available. Day or night, weekend or weekday, we answer the phone. For genuine emergencies in Auckland, we aim to be at the door within the hour.
What counts as an emergency
- Burst pipes — visible water, mains shut off, mains can't be shut off
- Hot water cylinder leak or tank failure
- Overflowing toilet that won't stop
- No water at all in the house
- Sewer backup into the house
- Gas smell (call us, then call your gas company — but call us first to make a plan)
Call 0274 267 267. If we can't get there fast enough, we'll tell you who can — and walk you through what to do in the meantime.
Blocked drains
A blocked drain is rarely just a blocked drain — it's a symptom. Tree roots, a collapsed gully trap, the wrong thing flushed down a toilet, decades-old build-up. The fix matters less than the diagnosis.
We clear it, then we tell you why it happened. If it's a one-off, that's the end of it. If it's going to come back, you know now — not the next time water won't drain at 9pm.
Drains we work on
- Bathroom — sinks, showers, bathtubs
- Kitchen — sinks, garbage disposal feeds, dishwasher waste lines
- Outdoor — gully traps, stormwater, downpipes
- Toilets — recurring blockages, slow flush, gurgling
- Mainline — sewer connections, repeated multi-fixture blockages
That's almost always a structural problem. Tree root invasion, pipe collapse, or a fitting installed at the wrong fall. Worth investigating before it gets worse.
Hot water cylinders
Hot water failures fall into two camps — the kind worth repairing, and the kind where it's cheaper to replace. We tell you honestly which one yours is.
A 25-year-old low-pressure cylinder with a leaking element isn't a repair job. A 4-year-old mains-pressure cylinder with a faulty thermostat is. The difference matters — to your wallet and to whether your hot water lasts the next decade.
What we do
- Standard cylinder swaps — like-for-like replacement
- Mains-pressure conversions — upgrading from low-pressure
- Element & thermostat replacement
- Tempering valve installation (compliance-required for new installations)
- Pressure relief valve replacement
- Cold water expansion valves
- Continuous-flow gas hot water — replacement and servicing (gas-fitting work referred to a certified gas fitter)
Call us before reaching for the breaker. If the element's blown and you reset the breaker, you can do further damage. Five minutes of diagnosis saves a much bigger repair.
Leak detection & repair
Hidden leaks are the worst kind — they show up on your water bill or as a damp patch in a wall, weeks after the leak started. By the time you notice, the damage is done.
We pinpoint hidden leaks before opening up walls or floors unnecessarily. The goal is to find the source first, then make the smallest possible repair to fix it. No demolish-first-ask-questions-later.
How we diagnose
- Pressure testing the system to confirm there's a leak and how big
- Acoustic detection — listening for water under floors and behind walls
- Moisture mapping — finding the wet zone before opening anything
- Thermal imaging where useful (hot water leaks particularly)
- Targeted access — open the smallest hole that gets the job done
Watch your water meter with everything turned off in the house. If the dial's still moving, you have a leak somewhere. Call us — finding it is what we do.
Tap, toilet & mixer repairs
The dripping tap that's driving you mad. The running toilet you can hear refilling at 2am. The mixer that mysteriously won't mix anymore. Small jobs we get to faster than the bigger guys, because we're not routing through dispatch.
We come with the common parts. Most of these jobs are done in one visit, often under an hour.
Typical fixes
- Tap washers, cartridges, full tap replacement
- Mixer cartridge replacement (kitchen, bathroom, shower)
- Toilet flush mechanisms — fill valves, flush valves, flapper seals
- Toilet wax seals — for that smell that's not going away
- Cistern button mechanisms
- Shower head replacements and flow rate fixes
- Spout O-rings and aerator cleaning
Save them up and we'll knock them out in one visit. Cheaper than separate callouts, and easier on everyone's calendar.
Bathroom & kitchen plumbing
Whether you're swapping a single fixture or pulling the bathroom apart for a refit, the plumbing has to be right or nothing else lines up. Fixtures that don't sit flush, drains that don't fall correctly, hot and cold reversed at the mixer — these are the small things that make a finished room look unfinished.
We work in straight from the existing pipework or, on full refits, plan the new runs with the builder so everything sits where it needs to. No surprises at fitout.
Common jobs
- Sink, basin, and vanity installation
- Toilet swap-outs (pan, cistern, full unit)
- Shower mixer and shower wall installation
- Bath installation — freestanding, drop-in, alcove
- Dishwasher and washing machine waste connections
- Kitchen mixer and pull-out spray installations
- Wall-hung vanity and concealed cistern coordination
Get us in before the gib goes back up. Catching the plumbing layout early saves expensive rework later.
New builds & renovations
Plumbing on a build is a relay race — slabs, framing, plumbing rough-in, gib, fitout. If we don't show up on time at our stages, the whole project slips. We don't slip.
We work to the architect's plans where they exist, and to common sense where they don't. We coordinate directly with your builder, and we flag things early when something on the plan won't work in the wall.
Stages we cover
- Pre-slab — under-slab drainage and waste runs
- Rough-in — hot, cold, waste, and vent rough-in for every fixture
- Pre-line inspections and pressure testing
- Fitout — fixture installation, commissioning, sign-off
- Compliance — Code Compliance Certificate documentation where required

Gas fitting
BMP is Benchmarc Plumbing & Gas Ltd — gas-certified as well as registered plumbers. You don't need a separate trade for gas work; the same person who does your plumbing also handles your gas, which means fewer scheduling games and one accountable point of contact.
We're deliberately conservative with gas work. If something doesn't smell right — literally — we err on the side of more checks, not fewer. Gas is the one part of the trade where "it should be fine" is never good enough.
What we cover
- Continuous-flow gas hot water — installation and replacement
- Gas hob, cooktop, and oven appliance connections
- Gas leak detection and repair
- Gas fitting for new builds and renovations (rough-in to fitout)
- Gas certifications for sale of property — Producer Statements (PS3/PS4) where required
- LPG ↔ natural gas conversions
- Annual gas appliance servicing and safety checks
Stop reading and call us — 0274 267 267. Then turn the gas off at the bottle or meter, ventilate the area, and don't use any switches, flames, or appliances until we've checked it.
Solar hot water & systems
Solar hot water is one of the biggest long-term savings on a power bill, and we install, swap over, and service it across Auckland. Done right, with the correct backup, you get free hot water for most of the year and never run cold.
We size the system to the household, set up gas or electric backup so winter and cloudy stretches are covered, and make sure the install is compliant and tidy. If you've got an old solar setup that's stopped performing, we'll diagnose it before you replace it.
What we cover
- Solar hot water system supply and installation
- Roof-mounted and ground-mount collector setups
- Gas or electric backup integration for cloudy days and winter
- Replacing or upgrading underperforming solar systems
- Solar cylinder and controller servicing and repair
- Honest advice on sizing and payback before you commit
Call 0274 267 267 for a straight answer on whether it stacks up for your home — no hard sell.
General maintenance
If it's plumbing or gas, we probably do it. The list above covers most of what comes through, but the trade has a long tail — the obscure connection on an obscure fixture in a 1920s villa, the body-corp shared system in a CBD apartment, the irrigation tap that froze last winter. We handle it.
If we don't do something specifically, we'll tell you straight, and tell you who to call.
Other things we do
- Pressure issues — low pressure, banging pipes, water hammer
- Hot/cold mixed flows ("warm" coming out of the cold tap)
- Outdoor taps and irrigation connections
- Body-corporate-related shared system work
- Pre-purchase plumbing inspections
- Smoke alarm interconnection (where part of plumbing/wiring rough-in)
- Insurance claim documentation and assessor-friendly reporting
Call 0274 267 267 and ask. If we don't do it, we'll point you to someone who does.
