The Challenge

The Collective, a large-scale co-living and student accommodation provider, reported persistent plumbing issues in the main ground floor toilet block at Nash House.

The existing urinals were suffering from:

• Faulty and incomplete fittings
• Poorly sized waste connections causing leaks
• Excessive silicone patch repairs by previous contractors
• Odour and hygiene concerns affecting residents and visitors

With the facilities in constant daily use, the client required an urgent remedial upgrade to prevent further disruption, improve hygiene standards, and maintain resident satisfaction.

Our Solution

VHL Mechanical attended site to deliver a full-service urinal replacement and waste system correction.

The works included:

• Isolating water supply and making the area safe
• Removing all three urinals and faulty fittings
• Installing new RAK concealed back inlet spreaders (square design for durability)
• Replacing traps, bottle traps, and flanged waste fittings
• Adjusting pipework – correcting from incorrect 30mm to standardised 32mm sizing
• Modifying waste connections with reducers, swept tees, and ABS wastepipe
• Applying solvent weld joints and silicone sealing for leak prevention
• Testing all connections for performance and ensuring no wall leaks
• Cleaning and reinstating the facilities for immediate use

All parts and labour were covered under VHL’s 12-month warranty.

Why It Matters

For large-scale accommodation providers like The Collective, plumbing reliability directly impacts resident satisfaction. Unresolved faults can lead to hygiene concerns, complaints, and reputational damage.

This project demonstrates VHL Mechanical’s ability to deliver fast, warranty-backed plumbing solutions that address the root cause — not just temporary fixes.
