Low water pressure makes showers weak, taps slow, and appliances inefficient. Mr. Clog diagnoses the cause — whether it's a failing pressure limiting valve, a partially closed isolation valve, a hidden leak, or a mains supply issue — and fixes it fast across all Sydney suburbs.

How It Works

01

We measure your water pressure at multiple points to pinpoint where the pressure drop is occurring.

02

We identify the cause — PLV failure, partial blockage, leak, or supply issue — and quote the fix.

03

We replace the PLV, clear the blockage, fix the leak, or install a pressure booster as required.

04

We retest pressure throughout the property to confirm normal flow has been restored.

Common Questions

The most common causes are a failing pressure limiting valve (PLV), a partially closed stop valve, scale build-up in older pipes, or a hidden leak reducing flow.

A PLV regulates mains water pressure down to a safe level for your internal plumbing. When it fails, you get either very low or very high pressure. Most need replacement every 10 years.

Yes — if your mains pressure is genuinely low, a pressure booster pump can significantly improve flow throughout your property.

Yes — excessively high pressure accelerates wear on fixtures, valves, and appliances. A correctly set PLV protects your entire plumbing system.
