High water pressure causing rattling pipes and low pressure upstairs?
-
Hey everyone, hoping someone with plumbing experience can chime in. We moved into a two-storey place in Glen Waverley a couple of months back, and recently whenever someone turns off a tap, the pipes inside the walls make this loud banging noise. On top of that, the water pressure in the upstairs bathroom shower has suddenly dropped over the past week, even though downstairs seems fine. My neighbor mentioned that sudden pressure drops inside the house could mean there’s a hidden break or pinhole leak somewhere along the internal pipe network that's bleeding off pressure. I definitely need a proper water leak detection melbourne company to inspect the system before a pipe fully bursts inside the wall frame. Has anyone had this exact issue, and who did you call to inspect it without ripping open plasterboards everywhere?

Mate, that sudden drop in upstairs pressure alongside noisy pipes is definitely a red flag that water is escaping somewhere in the line! We had almost the exact same thing in our townhome last year. Turned out a small coupling behind the laundry wall had cracked and was slowly leaking into the cavity. We didn't want to start smashing walls on a hunch, so we brought in https://leaksrus.com.au/ on a recommendation. They were awesome—they used acoustic listening equipment and thermal imaging to trace the pipe run through the walls without cutting a single hole until they pinpointed the exact spot. Took them less than an hour to find it. I'd definitely recommend getting them out ASAP before that hidden leak damages your wall timber or ceiling!

The rattling right when a tap shuts off is a classic sign of water hammer — the moving water slams to a stop and shakes the pipes in the wall. If your incoming pressure is on the high side, a pressure-reducing valve at the main plus a couple of water-hammer arrestors near the noisiest fixtures usually sorts it. The separate upstairs low-pressure symptom is worth checking at the same time, since high mains pressure and a partial blockage or small leak can show up together. I'd get a plumber to test the static pressure before buying any parts.
