Having been in the plumbing business for decades, I can tell you that low hot water pressure is a common issue, one that clients in Perth and beyond frequently call about. That frustrating moment when you’re ready for a warm shower, only to find a weak trickle instead, can be incredibly disruptive. Let me walk you through the common causes and fixes for hot water pressure drops and share some practical steps you can take to restore things back to normal.
- Check for Sediment Buildup in the Water Heater
Over time, sediment naturally accumulates in water heaters. This buildup can reduce water flow and impact pressure. Perth’s water has a high mineral content, so sediment buildup is often a culprit for reduced water pressure. If your water heater is older or you’ve noticed gradually decreasing pressure, sediment is likely to blame.
What you can do: Drain the tank to remove sediment buildup. This should be done once or twice a year to keep the heater running efficiently. If you’re unfamiliar with this process, I’d advise consulting a professional to handle it safely.

- Inspect Your Pipes for Mineral Deposits
Just as sediment builds up in your water heater, mineral deposits can accumulate inside pipes, particularly if they’re older or made of galvanized steel. These deposits restrict water flow and can lower pressure at your taps, especially when you’re using hot water.
What you can do: If your home has older plumbing, it might be time to upgrade to newer materials, like PEX or copper, which don’t suffer from the same buildup issues. While replacing pipes can be a larger investment, it’s one that often improves water pressure and overall water quality.
