Mario handled the situation very professionally and made a genuine effort to resolve the issue. Although the problem wasn’t ultimately fixed, he did everything he could to help and was clearly committed to finding a solution. I was a bit frustrated at times when I couldn’t reach him by phone, but I understand he was busy and short-staffed. Overall, I appreciate his effort, honesty, and professionalism throughout the process.
Mario is an absolute gentleman, my experience with Mario and his team from start to finish was amazing. We had an urgent issue at my 83 year old mother’s home with a serious blockage, Mario had the problem sorted and fixed without any issues and was a gentlemen to deal with. Keep up the amazing work 👌

No. In Australia, replacing an entire tap set must only be done by a licensed plumber. You may, however, replace a tap washer yourself, as that is considered minor maintenance.
Yes, a handyman can generally do simple, like-for-like tap replacements. However, more complex installations, such as work that involves rerouting pipes or changing a plumbing system, would need a licensed plumber. In Australia, tap replacement that involves disconnecting and reconnecting pipes requires a licensed professional by law.
It can take 1 to 2 hours to replace a tap, depending on the job’s complexity. At Optiflow Plumbing, our experienced plumbers take an average of 1 hour to replace any kind of tap.
Getting a tap replaced in Melbourne can cost between $80 to $150 for basic replacements and repairs. More complex installations can range from $160 to $550. Contact Optiflow Plumbing now for a tailored quote.
Tap washers should ideally be replaced every 1-2 years. However, this frequency also depends on the type of tap washer, water quality and how often it’s used. It is recommended to have your tap washers inspected every 6-12 months to monitor their function and check for signs of wear and tear.
