The Challenge
During a scheduled tank clean and chlorination at a private Central London property, our engineers identified a faulty ball valve. Though often overlooked, a failing valve can lead to constant overflow, bacterial stagnation, and even system pressure issues.
Our Solution
NT Cloke carried out a comprehensive water hygiene service, including:
- ✅ Full tank clean and chlorination
- ✅ Replacement of faulty ball valve
- ✅ Water sample taken for lab testing
- ✅ System fully recommissioned for safe operation
All works were completed in one visit, with minimal disruption to the client.








Why It Matters
🔹 Prevents overflow and water waste
🔹 Reduces risk of Legionella and other bacteria
🔹 Protects plumbing and pump systems from strain
🔹 Keeps your property safe, compliant, and efficient
NT Cloke provides full-system care — not just tank hygiene, but also valve checks, pump servicing, and compliance testing — all under one roof.
