Install Water Heater

$500

Noraville NSW 2263, Australia

27th Oct 2026

Install customer-supplied electric hot-water system (Time and Material) I need a licensed, insured tradesperson to install a new electric storage hot-water system at Noraville NSW 2263. I have already purchased the replacement unit and it is on site. So I only require installation, not supply of the unit or removal/disposal of the old system. The installation location is a ground-level utility/storage area beneath the house. It has concrete flooring and practical access, similar to a workshop/service space rather than a finished internal room. Existing water pipework and electrical supply are in place. Please provide a fixed, all-inclusive quote for: Positioning and plumbing in the customer-supplied hot-water system All required valves, fittings, pipe connections and PTR discharge line Licensed electrical connection, testing and electrical compliance certificate Confirmation that the completed installation meets current NSW requirements GST, labour and all minor materials required to complete the job I would prefer one suitably qualified person who can complete both the plumbing and electrical hot-water connection. Otherwise, please quote for the complete job including both licensed trades. Please state your earliest availability. Photos and measurements can be supplied.

Move Water Heater for Paving work and move back

$350

Marsfield NSW 2122, Australia

30th Sep 2026

I am having paving work done in my front courtyard and need a qualified plumber to temporarily disconnect and relocate our 270L heat-pump hot water system from the front courtyard to the back courtyard while the paving work is completed. The job will involve two visits: 1. Disconnect and relocate The hot water system will need to be disconnected, drained/emptied as required, and safely moved from the front courtyard to the back courtyard. This needs to be completed either Tuesday 6 October or the morning of Wednesday 7 October, before the paving work begins. 2. Move back and reconnect Once the paving is complete, the hot water system will need to be moved back to its original location and fully reconnected and tested. The paving contractor expects the work to be completed by Friday 9 October or Monday 12 October, so the exact return date can be coordinated once the paving is finished. Important: The finished paving level may be slightly different from the existing ground level. The plumber will therefore need to be able to modify/shorten/extend the existing copper pipework as required to suit the new installation height and reconnect the system correctly. The unit is approximately 270L, so please allow for its size and weight and any equipment/additional person required to move it safely. Please quote for the complete job, including both visits, disconnection, relocation, return, reconnection, any minor copper pipework modifications required, and testing the system after reinstallation.

Disconnect and remove 2 solar hot water heaters

$250

Neutral Bay NSW 2089, Australia

27th Jul 2026

These solar hot water heaters (not powered, just has water running through it) are rusty and leaking, I need to decommission and remove. Each heater panel is about 2x1m. I am fit and able to help lift, but I can’t do it alone; ideally I need a plumber who can disconnect / block off the pipes from the internal HSW. All i really need is for someone to disconnect it at the source, and then help me get it off the roof. I’ll do the rest. Flat room, easy access.

Brilliant work, helped me solve a lot of problems as we went. Very professional. Thank you ☺️
