3. Installation benefits of Speedfit fittings include ease of use, fast installation, and maintenance-free performance.
Drop-Pipe Systems When designing and installing central heating systems with radiators supplied by pipework from an upper floor, care must be taken to prevent air trapping in the upper floor pipework. This can lead to increased pressure and potential pipe bursts. Automatic or manual air vents should be installed at the highest points to remove trapped air.
Connection to Cylinders & Water Heaters Speedfit can be used in both sealed and open vented heating systems. For unvented pressurized cylinders, insertion depths on compression joints must be checked, and standard pipe inserts are recommended. Discharge pipes from temperature and/or pressure relief valves must be metal, as per UK Building Regulations.
Connection to Pumps and Valves Speedfit Pipe should be connected to circulating pumps and motorized valves according to specific guidelines. Pipes must be clipped close to components for support and vibration reduction. Heavier equipment should have independent metal bracket support.
Connecting to Cold Water Storage Tank The minimum distance for solder connections on copper pipe inserted into a Speedfit Fitting is 450mm. The Speedfit Tank Connector should be hand-tightened only to avoid damage.
Radiator Connections Pipes should be run centrally to the radiator position, exiting through a single gang box. Metal reducing sets are not suitable for use with Speedfit Fittings or Pipe.
Electrical Continuity Installers should ensure compliance with IEE Regulations regarding electrical continuity. Supplementary bonding may not be required for metal taps and plastic pipes unless connected to the metallic building structure.
Installing Pipework Speedfit Pipe is flexible and can be threaded through concealed spaces, reducing installation time and risk of damage. It requires no jointing materials, eliminating fire risks associated with soldering.
Pipework Insulation Insulation requirements for Speedfit Pipe are the same as for copper, complying with BS EN 806 and other standards. Proper drilling of joists is essential to maintain structural integrity.
Timber and Steel Framed Construction Speedfit is suitable for both timber and steel frame constructions. Care must be taken not to compromise structural integrity or fire resistance when installing pipework.
Specifications and Procedures
  • Wet Plaster: Speedfit Pipes should be channeled into walls and protected with sleeving to prevent damage from expansion and contraction.
  • Exposed Pipework: Long runs of exposed pipes may sag due to expansion. Boxing in or using rigid copper pipes is recommended.
  • Chemical Effects: Only water or oil-based paints should be used. Avoid contact with aggressive chemicals and consult the Technical Advisory Service for compatibility.
  • Acoustic Properties: Speedfit Pipes are designed to be silent and absorb vibrations, eliminating issues like water hammer.
  • Laying of Pipe in Concrete and Masonry: Pipes are available in coil lengths and should be protected against rodent attacks.
System Testing and Commissioning
  • System Testing: A hydraulic wet test is essential, with testing at 2 bar for 10 minutes followed by 10 bar for 10 minutes.
  • System Commissioning and Flushing: Flushing is crucial to remove contaminants. Disinfection with chlorine is recommended, ensuring solutions only contact internal surfaces.
Common Problems and Identification
  • Burst or Melted Pipe: Caused by freezing or excessive heat exposure.
  • Dissolved Fitting: Results from chemical attacks, often due to acid-based solder flux.
  • Weep from Fitting: Occurs when the pipe is not fully inserted or 'O' rings are damaged.
