Plumber required: Disconnection of hot water system

$500

North Sydney NSW 2060, Australia

5th Nov 2026

Licensed Plumber Needed – Disconnect Hot Water System & Isolate Pipework (Class 2 Apartment, NSW) The apartment is in a Class 2 building and is about to undergo a full interior renovation, starting with magnesite flooring removal. A new hot water system will be installed later. For this job, I need a licensed plumber to: Isolate and disconnect the existing hot water system, drain the tank, and move the unit aside so the riser behind it can be inspected. The unit doesn’t need to be removed from the apartment. Drain, isolate and cap the pipework that runs just above the slab through the magnesite-affected areas. Remove these pipe sections if possible. Please include this in your quote. If removal isn’t included, please cap them so they’re fully disconnected and safe for the flooring team to lift. Leave all capped points secure and clearly marked. Cold water needs to stay on to at least the toilet / kitchen tap for the trades. Please note: Power to the hot water system will be isolated and disconnected by my electrician before you arrive. This is a strata building. Please let me know if the water needs to be shut off at the riser so I can arrange it with the building manager. Requirements: 1. A current NSW plumbing contractor licence. 2. Public liability insurance, with a copy of your current Certificate of Currency. 3. Notice of Work and Certificate of Compliance lodged where required. If interested, please send: 1. Your quote, with pipe removal priced separately if possible 2. Your availability 3. Your licence number
