Beneath the Bricks: Securing a Safer Water Supply in Surrey Hills
Ignoring ageing pipes or fluctuating water pressure can lead to serious plumbing problems over time. A dripping tap or noisy toilet refill may seem minor, but these small warning signs often signal something bigger happening behind walls or beneath the ground.
This was the situation for a homeowner in Surrey Hills. Their main water line ran under the front brick pavement, was old, difficult to access, and increasingly unreliable. While no major burst had occurred yet, the risk was clear: a failure would mean extensive brickwork removal, potential water damage, and costly repairs.
Rather than waiting for an emergency, the homeowner contacted O’Shea Trades, a trusted plumber Surrey Hills residents rely on, for a long-term solution.
Comprehensive Water Line Replacement
From the first inspection, it was evident that patch repairs wouldn’t suffice. The safest and most cost-effective option was a complete water line replacement, rerouted to a more practical and accessible path.
O’Shea Trades developed a plan to install a brand-new copper water line from the meter, across the back of the garage, and into the closest internal connection point.

Step 1: Safe Disconnection and Removal
The water supply was carefully shut off. Old lead connections at the meter and beneath the house were disconnected, removing the outdated section permanently. The line beneath the brick pavement was completely deleted, eliminating the hidden risk that had existed for years.
Step 2: Excavation with Care
A new trench was dug from the meter to the rear of the garage and extended under the house. Great care was taken around footpaths, trees, and other property features, demonstrating O’Shea’s commitment to both professional workmanship and respect for the homeowner’s property.
Step 3: Installing High-Quality Copper Pipework
The new supply line was built using durable copper pipes, chosen for their strength, longevity, and corrosion resistance. Each section was precisely measured, cut, assembled, and securely crimped. Pipework was firmly clipped in place to prevent movement and ensure long-term stability.
Where the copper ran along the brick wall at the rear of the garage, protective lagging was installed to shield exposed pipes from environmental conditions, supporting efficient performance over time.
Step 4: Pressure Control for Longevity
A pressure control valve was added at the water meter. Excessive water pressure can quietly damage internal plumbing over time, causing issues like leaking taps, failing toilet valves, split hoses, and wear on hot water systems. Regulating pressure at the entry point protects every connected fixture in the home.
Step 5: Additional Features for Convenience
To improve usability, a new garden tap was installed near the meter by teeing into the main supply. This provides outdoor access without affecting indoor water flow.
Step 6: Testing and Quality Assurance
After installation, the system was rigorously tested. Water was restored gradually, joints were inspected, and the line was flushed to remove air and debris. Only once consistent pressure and zero leaks were confirmed was the trench backfilled and the site tidied.

The Result: Reliable Water Supply and Peace of Mind
The homeowner gained:
- Consistent, reliable water pressure throughout the property
- Smooth tap operation and correctly refilling toilets
- Protection for the hot water system against pressure-related wear
- Assurance that the main water supply is professionally installed and built to last
