It’s also a legal requirement to submit the results to your local water authority, helping protect the entire community’s water supply. </div> <div> <br/> </div> <div> If your property has an RPZ, staying on top of annual testing isn’t just compliance... it’s peace of mind. ✔️ </div> <div> <br/> </div> <div> - Dunstone Bros Plumbing &amp; Roofing (03) 5446 1535 </div> </div> Mon, 20 Apr 2026 04:39:36 GMT https://www.dunstoneplumbing.com.au/what-is-backflow-testing thumbnail main image https://www.dunstoneplumbing.com.au/what-is-hvac <div data-rss-type="text"> <div> <b> <span> You might have heard your plumbers or tradespeople throw around the term  <span> HVAC. </span> </span> <br/> </b> </div> <b> <div> <b> <br/> </b> </div> HVAC </b> is an acronym for services surrounding Installation, maintenance, and repair of <b> H </b> eating, <b> V </b> entilation, and <b> A </b> ir <b> C </b> onditioning systems.  <div> <br/> </div> <div> HVAC Services ensure indoor air stays comfortable, safe, and energy-efficient  <span> year-round. </span> </div> <div> <div> <span> <br/> </span> </div> <div> <span> <br/> </span> </div> </div> </div> Mon, 20 Apr 2026 04:13:57 GMT https://www.dunstoneplumbing.com.au/what-is-hvac thumbnail main image https://www.dunstoneplumbing.com.au/what-are-those-drains-outside-of-my-house-used-for <div data-rss-type="text"> Ever wondered what those little outdoor drains/grates are for?  <div> <br/> </div> <div> When a plumber says “O.R.G”, they’re talking about the <b> Overflow Relief Gully </b> .  </div> <div> <br/> </div> <div> Its job is to act like a safety drain outside your house, so if the main sewer ever blocks up or overflows, the wastewater spills out there instead of backing up inside your home.  </div> <div> <br/> </div> <div> A <b> storm water drain </b> is for rain water only.  <div> <br/> </div> <div> No question is a silly question.
