Repair Leaking Bathtub Hot Water Tap

$100

Chatswood NSW, Australia

5th Aug 2026

I’m looking for a qualified plumber to repair the hot water tap on the left side of my bathtub. The problem is: * The hot water tap no longer works and no water comes out when I turn it on. * Even when the tap is turned off, water continues to leak. * Before it failed, it made a strange noise, as if there was air trapped in the pipes. The water pressure then started surging on and off before the tap stopped working completely. I have two videos showing the problem and can send them to you before you come if needed. Please bring any tools or parts that may be required to repair the tap. When submitting your offer, please let me know your earliest available date and time to come and repair it. Thank you!

Johnny is very professional, punctual and effective. Highly recommended to anyone who need plumbing done.

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!
