Plumbing & Mechanical

At PM Technical Services, our Plumbing & Mechanical Works services provide expert installation, modification, and repair solutions for hot and cold water systems, pumps, valves, and associated pipework. We specialise in legionella risk mitigation through targeted remedial interventions, ensuring system integrity, hydraulic efficiency, and full compliance with UK regulations including ACoP L8, HSG274, Water Regulations, and Building Regulations. 

 

Our works are meticulously planned and executed to minimise disruption, optimise water flow, prevent stagnation, and enhance safety - particularly in commercial, industrial, healthcare, and residential settings. Led by our directors, who collectively bring over 20 years of hands-on plumbing and engineering experience - from pump installations/replacements to dead leg removal and system surveys - we deliver precise, reliable solutions integrated with water hygiene and mechanical services.

In-Depth Features of Our Plumbing & Remedial Works Services

​

Pipework Installation and Modifications   

Professional fabrication, routing, and integration of new or modified pipework (copper, steel, plastic) for hot/cold water distribution, ensuring optimal flow rates, pressure balance, and minimal stagnation zones. This includes system extensions, rerouting for efficiency, and integration with existing building services. 

​

Pump Installations and Replacements

Selection, installation, and commissioning of booster pumps, circulation pumps, and specialist water system pumps. We handle full removal of faulty units, hydraulic testing, and alignment to restore or enhance system performance. 

​

Dead Leg Removal and Stagnation Prevention

Identification and engineered removal of dead legs (redundant pipe sections prone to bacterial growth) through precise cutting, capping, or rerouting. This critical remedial work eliminates low-flow zones, reducing legionella risks and improving overall water quality.

​

Thermostatic Mixing Valve (TMV) Servicing and Installation

Fail-safe testing, recalibration, servicing, and new installations of TMVs to prevent scalding and control bacterial proliferation. Compliant with HTM 04-01, we ensure accurate temperature blending at outlets. 

​

Leak Repairs and General Remedial Works

Rapid detection and repair of leaks, joint failures, or corrosion issues using advanced techniques (e.g., welding, compression fittings, or pipe freezing for live systems). Includes valve replacements, strainer cleaning, and fabric repairs to maintain system pressure and prevent water damage. 

​

Hot and Cold Water System Surveys

and Recommendations  

Comprehensive surveys including temperature profiling, flow checks, and risk identification, followed by detailed remedial recommendations and implementation to address non-compliances.

​

Compliance and Risk Management

All works supported by bespoke Risk Assessments and Method Statements (RAMS), COSHH evaluations, and adherence to confined space/working-at-height protocols for safe execution.
