Electric Hot Water System Leaking

$150

Cherrybrook NSW, Australia

22nd Aug 2026

New electric hot water system has been installed just over a year. Issue: water constantly dripping 24 hours from the pressure relief valve soon after installation. Then pressure relief valve had been replaced but it worked for about a couple months and started dripping again nonstop. When the pressure relief valve is turned on manually, significant amount of hot water pouring out nonstop. Other information: - we have solar panels installed - our old hot water system didn’t seem to leak before installing this new one a year ago

Hot water tank

$10

St Marys NSW 2760, Australia

20th Aug 2026

We are after a Rheem 415L Electric Hot Water Heater to be supplied and installed at our warehouse in St Marys, inside the bathroom area. The hot water system will be connected to a device that measures water volume, so we require the outlet water to be kept below 80°C and the water pressure to be 60 psi or lower. We also need a hot water pipe run approximately 5 metres from the water tank to one of our machines. The pipe can run up the wall, through the wall to the other side, and then split into two separate tap outlets. Standard garden-style tap outlets are fine. Please include all required plumbing, fittings and pressure control in the quote.

The pressure when I turn the tap to hot in the kitchen is non existent. Works fine for cold and in the rest of the apartment. I believe it has a pressure limiter that needs to be removed. I also need a pipe in my bathroom sealed.

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!

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!
