Gas Cooktop Installation in Elwood, 4-Burner Replacement with New Isolation Valve
Gas Cooktop Installation in Elwood, 4-Burner Replacement with New Isolation Valve, a Prime Plumbing & Gasfitting plain-English guide to gas cooktop installation elwood for Melbourne homeowners. Below we cover what works, what doesn't, and when to call a licensed plumber.
Quick answer: This gas cooktop installation Elwood case study walks through replacing a 12-year-old 4-burner gas cooktop in an Elwood townhouse, owners had bought a new stainless steel unit and needed the install done with a Certificate of Compliance. New isolation valve fitted while we were in there (the old one was working but stiff), compliant flexible hose, full pressure test. 2-hour job.
What we found at the Elwood property
The home is a modern Elwood townhouse with a 12-year-old 4-burner gas cooktop. The owners had bought a new 60cm stainless steel cooktop and wanted a professional install rather than DIY (which isn't legal in Victoria anyway, gas work requires Type A Gasfitter).
What we assessed before the install:
- Existing gas line in good condition, 1/2" copper from the meter to the cooktop position
- Isolation valve at the cooktop end, working but stiff (12 years of disuse)
- Flexible gas hose: original from 2014, on the limit of Australian Standard expected life
- Cooktop cutout: 60cm × 50cm benchtop opening, matching the new unit's spec
How a gas cooktop installation Elwood job actually goes
1. Gas isolated and old cooktop removed
Gas turned off at the cooktop isolation valve (after confirming the meter-side gas was still flowing for the other appliances). Old cooktop disconnected, flexible hose detached, electrical disconnected (cooktop also needs power for ignition), unit lifted out of the benchtop.
2. Cutout checked + new isolation valve
The benchtop cutout was correctly sized for the new unit (sometimes they're slightly different and need adjustment). We replaced the stiff isolation valve with a new quarter-turn ball valve, minor cost during an already-open install, big convenience for future maintenance.
3. New flexible gas hose
Old AS 1869 hose replaced with a new one of the correct length and rating. The hose was about 8 years old, still serviceable but at the point where preventive replacement makes sense rather than waiting for end-of-life.
4. New cooktop installed
New unit positioned in the cutout, levelled, and connected:
- Gas connection to the new flexible hose
- Electrical connection (cooktop ignition draws from a standard power point under the benchtop)
- Mounting brackets to secure to the benchtop
- Sealant around the cooktop edge to prevent moisture ingress
5. Pressure test + leak test
- Pressure-tested the gas line at working pressure for 30 minutes
- Soap-tested every connection
- Lit each burner to confirm ignition and flame quality (blue flame = correct gas-air mix)
6. Certificate of Compliance
Issued same day, emailed PDF. The CoC covers the gas connection work and certifies the install meets AS 5601 (Gas Installations).
Total time on site: about 2 hours.

Frequently asked questions
No. Gas appliance installation requires a Type A Gasfitter license in Victoria. The electrical connection portion can sometimes be DIY-equivalent (a standard power point) but the gas connection cannot.
Typical replacement install: 2-3 hours including all testing. New install (no existing gas connection) is longer, 4-6 hours plus possible benchtop modification.
Sometimes (low-end units), but the included hose is often not the correct length or rating. We supply and fit a hose to the specific install, including replacing any aged existing hose.
A Certificate of Compliance is the document that certifies the gas work meets AS 5601, issued by the gasfitter at job completion. You need it for: building insurance claims related to gas, property sale conveyancing, and as evidence the install was done legally.
Yes, the old cooktop stays connected and operational until install day. The change-over happens during the install (typically 1-2 hours without cooktop access).
