Why Wait for an Emergency?
A sudden drainage failure can bring your operations to a grinding halt, resulting in lost revenue, health and safety hazards, and emergency call-out fees. Pre-Planned Maintenance (PPM) solves this by taking a proactive approach to your drainage network.
At Arma-Rod, we work closely with commercial clients across London and Hertfordshire to design bespoke maintenance schedules. By regularly cleaning, descaling, and inspecting your drains, we ensure they remain free-flowing and fully operational 365 days a year.

The Arma-Rod PPM Advantage:
What Does a PPM Contract Include?
Every commercial site is different. A busy restaurant in Central London will have completely different drainage needs compared to an industrial warehouse in Hertfordshire. Our services can include any combination of the following:
High-Pressure Jetting
Regular scouring of the internal pipework to remove scale, silt, and debris build-up before it causes a full blockage.
CCTV Drain Surveys
Periodic visual inspections of the drainage network to monitor structural integrity and catch early signs of fractures or root ingress.
FOG Management
Crucial for the hospitality sector. We schedule routine emptying and cleaning of grease traps and interceptors to prevent fat blockages.
Urinal & Trap Descaling
Electro-mechanical descaling of urinals and primary pipework to eliminate foul odours and slow drainage in public washrooms.
