Plumber: help fix whining noise in roof water pipe

Johnathan requested 3 quotes from Plumbers in Nunawading

  A week ago, every night without fail, between 10pm to 11pm, a whining noise starts in our roof cavity.

It's a high pitched noise in these pipes (photos attached). Which runs throughout the night and stops next day before noon (again without fail).

We isolated it down to something water related. When the toilet flushes or water tap is turned on (and water pressure released), the noise quietens a little.

Whining resume after toilet refills, or water tap is turned off.

This is a two storey house with central evap cooling & ducted heating. The HVAC tech came out recently and said it wasn't related to those.

We do have solar. Have tried turning off the inverter at night. Doesn’t seem to affect noise. But we do have solar hot water so could be related to that. See below for hot water tank photo.

We're hoping to an experienced & licensed plumber could come out sometime 8-10am (while noise is still going) to fix the issue.

Let me know if any questions.

Thanks
Johnathan
