Fix my solar hot water system

$200

Picton NSW 2571, Australia

3rd Sep 2026

I have an evacuated tubes system but I don’t think water is getting up to the roof or back again. Both pipes that run to the roof are cold. (Still have hot water from off peak electric heating at night.) No alarms are showing on the controller. There doesn’t appear to be water in the valve window thing on the pipe that runs up to the roof. I’ve turned everything I can off and on again and disconnected and reconnected every sensor. Unit is under house with access through garage.

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 ☺️

Diagnose & Repair Dux 100L Electric Hot Water System (No Hot Water)

$180

Sydney NSW 2010, Australia

14th Jul 2026

Hi, I'm looking for a licensed plumber (or suitably qualified hot water specialist) to diagnose and repair my Dux Proflo 100L electric storage hot water system. The issue: - No hot water anywhere in the apartment (including the kitchen). - The system was working previously and has now stopped heating. - Power is on to the property. About the installation: - Dux Proflo 100L electric storage hot water system. Installed inside a cupboard approximately 1 metre above the floor. - I am the owner of the apartment. - I have access to all electrical switchboards. - A ladder is available if required. - Plenty of photos are attached showing the unit and surrounding area. Ideally, I'd like the system repaired if the fault is something like the heating element, thermostat or another replaceable component. If the cylinder itself has failed or isn't economical to repair, I'd appreciate a quote to: - Remove and dispose of the existing unit. - Supply a replacement hot water system (around 80–125L is fine). - Install and commission the new unit. Please let me know: - Your availability - Whether your offer includes diagnosis - Any additional costs for parts if required Thank you!

Best communcation ever, water is finally warm. Thank you so much Dean!

Switch hot water and cold water valve under sink

$50

Guildford NSW 2161, Australia

14th Jul 2026

Dishwasher installer informed us the dishwasher is connected to the hot water valve and it needs to be connected to the cold water. We need a plumber to switch the two so it connects to the cold water or if switching it not allowed to put in the correct ones. I’ve inserted photo showing the dishwasher being connected to the hot water underneath.

There was more to the job we didn’t realise and he was happy to do the new fixes right away. Thanks!
