KNOX Plumbing & Gas
The plumber customers call when others have already said the job is too hard.
That last point is worth taking seriously if you've had trouble getting other plumbers to commit to a difficult property or a complex job. The business has been operating for around 13 years as a sole trader, meaning you're dealing directly with the licence holder on every job rather than a rotating roster of subcontractors. Reviews span the full spectrum from simple tap installs to full granny flat fitouts and septic system overhauls, so the business appears genuinely versatile rather than narrowly specialised — useful if your job crosses a few trades at once.

About KNOX Plumbing & Gas
Nick is the face and driving force behind KNOX Plumbing & Gas, and his team — most often mentioned alongside 'Ant' — tackles jobs that other tradies quietly walk away from. Several customers specifically note that Nick turned up on sloping or difficult blocks where competitors had refused to quote, and delivered results that exceeded expectations. The business spans a wider range than the 'plumber' label suggests: hot water system replacements (including tight, awkward installs under stairs or in cramped locations), full granny flat fitouts, septic tank repairs and connections, waterproofing, bathroom and laundry renovations, rainwater tank installations, gas work, and even drainage repairs for soggy yards. One customer saved $25,000 by having Nick repair and clear an existing wastewater treatment system rather than replace it — a detail that signals genuine problem-solving over upselling. Nick runs 24/7 emergency availability and has a documented track record of same-afternoon and Sunday-night callouts for burst pipes, leaking hot water systems, and gas leaks. A recurring detail across reviews is that the crew shows up with a vacuum cleaner and leaves the work area clean — something customers flag specifically because it surprises them.
Best for: emergency plumbing callouts on short notice, hot water system replacements in awkward or constrained spaces, full bathroom and laundry renovation plumbing, and difficult jobs on sloping blocks or complex properties that other tradies have declined.

Does KNOX Plumbing & Gas do emergency callouts outside business hours?+
Yes — multiple customers confirm Nick is reachable and responsive after hours and on weekends. One review describes him arriving within 10 minutes during an emergency flood, another records him replacing a hot water system on a Friday afternoon after a lunchtime call, and a third thanks him for turning out on a Sunday night to fix a shower. He answered a phone call before 9am on a Sunday in at least one documented instance. If you have an urgent job, it's worth calling directly rather than assuming availability.
What areas does KNOX Plumbing & Gas service?+
The business is based in Eli Waters, QLD, and reviews reference completed jobs in Sunshine Acres and on the Sunshine Coast in addition to the Fraser Coast area. Reviews don't specify a hard boundary for the service area, so if you're outside the immediate Hervey Bay region it's worth a quick call to confirm they cover your location before booking.
Is KNOX Plumbing & Gas able to handle larger renovation or construction jobs?+
Reviews confirm Nick and his team have completed full granny flat plumbing fitouts from rough-in to fit-off, full bathroom and laundry renovations including waterproofing, and large septic tank connection jobs. One customer notes Nick also accommodated last-minute changes mid-project without issue. As a sole trader operation, it's worth discussing project timelines upfront for anything that will run for multiple weeks, to make sure scheduling aligns.
What do customers say about pricing?+
Several reviews specifically flag pricing as fair or competitive. One customer obtained multiple quotes for a gas hot water system and chose KNOX as both the best-priced and quickest option. Another notes the service was 'cost-effective,' and a third describes Nick as 'reasonably priced.' Reviews don't mention any pricing surprises or disputes, which is a reasonably reliable signal across 54 reviews.
Does Nick handle gas work as well as standard plumbing?+
Yes — the business trades as KNOX Plumbing & Gas, and reviews include jobs involving gas hot water system replacement and a gas regulator repair where a leaking regulator was replaced within a few hours of contact. If you have a gas appliance, gas line, or regulator issue, this is within their stated scope. For any gas emergency, customers report Nick responds quickly.
