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.
