10/10
Mario renovated our kitchen and did an amazing job!! Great service, professional and great communication. Highly recommend!!!
I can’t recommend Mario and Optiflow highly enough. I needed an emergency job done on my blocked drains and Mario organised to be here within 2 hours. He went above and beyond to clear all the drain pipes and have us up and running very quickly. Polite and helpful customer service that was second to none.
Mario and Optiflow truly deserve 5 stars. He has been incredibly helpful from the beginning as we had a major plumbing issue to deal with. The fact that he takes the time to explain the solution to his clients irrespective of how many questions you ask or what time you call is testament to his customer-centric approach. Amongst a sea of dodgy plumbers and shady workmanship, it is refreshing to see someone who is actually willing to help those clients that are in need of his services. If you’re looking for someone else – don’t. Mario is your guy.
I reached out about a water leak and got a super quick response. The plumber was professional, helpful, and guided me through the fix right away. Really appreciated the fast support and clear advice. Highly recommend!
Very helpful in explaining what was going on and know what they’re doing.
Mario came out and unclogged the kitchen sink quickly and efficiently. He was fast, reliable and reasonably priced.
Would definitely recommend!
The quality of work I’ve seen from the blokes at Optiflow is unmatched! They are phenomenal guys who take pride in their work and genuinely care about their customers!
Mario was punctual, quick and honest. Everything you want in a tradesman. we are super please with the service provided by the optiflow team.
Professional and prompt service .
Helpful explanation was provided as well.

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.
