Solar hot water evacuated tube repair or replace plumber
$150
Glebe NSW, Australia
30th Sep 2025
We have a gas boosted solar system, evacuated tube solar. The system needs an inspection to work out what’s going on. 1. The solar component seems like it might not be working and continuously on gas boost for hot water? 2. We are getting an attic room installed. The insulated pipes from the evacuated tubes run across the roof space, they need to be placed down at joist level. 3.there is an old gravity cylinder in the roof space. Does the water reticulate through that as part of the current system. If so, it needs to be bypassed, and the tank drained, so the tank can be cut up and removed.
I would recommend Dario

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.
