I had my hot water heater replaced recently with this https://www.samedayhotwaterservice.com.au/product/rheem-stainless-steel-80-litre-hot-water-system/?gad_source=1&gad_campaignid=17613708470&gclid=Cj0KCQjwyIPDBhDBARIsAHJyyVhhPaId09ffQ6ACr80L9LZZA9X07VymvcEmnsxiEFNso2Q7tQLXy9gaAkYDEALw_wcB and the tech installed it set to a fairly low temperature, which he said he was required to do. I have the manual and a little key thing that he left for me (pictured) but I can't for the life of me figure out how to adjust the temp, and the manual only says to get an electrician to do it. Just looking for someone who knows their way around a unit to bump it up for me! I work from home so during the day is best. Unit is easily accessible in a hall cupboard.

need a short ~3 m trench 600mm deep dug across lawn for electrical cable. Doesn't need to be done until mid-August. There may be other services under the lawn eg. water or gas. THere are other electrical cables adjacent.

Need a smoke alarm battery changed. Just started beeping today. I own the property. Unit has been installed at the top of a fold down ladder to get to my attic so if you're ok to use that you don't even need to bring a ladder.

There are 3 downlights in my apartment not working. I need someone to please come and fix the lights please.

Need to two light fittings swapped to pendular lights - needs to be certified electrician

I have 5 hardwired downlights that no longer work. I need them replaced. 1 in laundry, 2 in kitchen, 2 in bedroom. Bought new bulbs but they still don't work so I am guessing the transformers have gone

Need an electrician to install a few extra powerpoints in the apartment. Need done today (Friday) or tomorrow (Saturday)

Install two electrical power points (one extension lead can probably be connected to an existing point) to power two security cameras. One to be installed near front letterboxes of apartment and the other in the basement. - Due date: Flexible

I have 2 double sockets in my apartment, 1 which doesn't work, and another which has come away from the wall exposing internal wiring. I would like them made safe and replaced if necessary. I would also like advice with regard to installation of additional sockets. - Due date: Flexible

Need a new GPO/power point installed in a newly built apartment. - Due date: Flexible

I need a registered electrician to install a power point in the bathroom next to the toilet for a bidet install. The wall is a hollow tile wall that's 11cm away from the real wall. There's an access panel/hatch in the ceiling for the wiring. - Due date: Flexible

The power supply has disconnected from the string of fairy lights and I’d lose a qualified electrician to rewire/attach it again. Thanks :) - Due date: Flexible
