Hot water - no pressure
$400
Bondi Beach NSW, Australia
9th Sep 2025
Our hot water has been 'playing up' for several years but getting increasingly frequent over the past 6 months. Some times it will run fine but other times nothing even comes out of the tap or shower.... Left the shower on full hot water last night for 30 minutes and literally no water flowed. Switch to cold water, full pressure. We have a separate hot water tank, which is not that old (see photos for details).


Really great service

Hot water system TPR valve discharge pipe install
$800
North Sydney NSW 2060, Australia
3rd Sep 2025
Hot water system in apartment has been repositioned and needs a new discharge pipe installed. The system is ~1.5m from the existing drainage pipe (in pic). Looks like the TPR valve is at least 10cm higher than the drainage pipe. Looking to get a pipe run along the wall and through a riser. A small notch would need to be cut in the riser to get it through. Would prefer to talk through this piece of work to fully scope it out before confirming it.


Really excellent work. Very grateful for Diego’s work.

Inspect hot water heater
$100
Rushcutters Bay NSW 2011, Australia
1st Aug 2025
Inspect a hot water heater to determine if it needs to be replaced or it should be fixed. It is currently not working. The power supply has recently been tested a few months ago, when a number of internal cables were replaced. If it needs either, to then provide a quote for the repair or replacement. It is an Aquamax 80L - of unknown age, looks in good condition. When I rang the company on the sticker they said likely > 10 years old and may be better to just replace.


Dario was a great help ! Highly recommend.
