Design and Installation

• 1.Are all companies and individuals engaged to work on your plumbing installations affiliated to and members of approval schemes, such as:<br><br>• CIPHE (Chartered Institute of Plumbing and Heating Engineering) Approved Contractor Scheme<br>• CIBSE (Chartered Institution of Building Services Engineers)<br>• Member of the Water Industry Approved Plumbers' Scheme (WIAPS) or similar?

  Yes

  No

  N/A

• 2. Have measures been considered to minimise potential water damage especially when using modern methods of plumbing including the boosted water system?

  Yes

  No

  N/A

• 3. Have measures been considered to minimise potential water damage especially when using modern methods of plumbing including the boosted water system?

  Yes

  No

  N/A

• 4. Has consideration been given to theinstallation of several small pumps arranged in parallel rather than a single large, variable speed drive pump?

  Yes

  No

  N/A

• 5. During the construction processes, was/is phased testing and inspection of pipework carried out as the build progresses?<br><br>• On a floor-by-floor basis?<br>• On a zoned orsectional basis?<br><br>Particularly where installations will ultimately be concealed in wall, floor or ceiling voids on completion.<br>Are these formally recorded?

  Yes

  No

  N/A

• 6. Following on from question 5 above, have full inspections and full commissioning tests been carried out on all new systems in their entirety?<br><br>• Including all equipment and fittings at their working pressure?<br>• In line with equipment supplier's guidelines?<br>• For a minimum commissioning period of not less than 8-hours and attended for its duration?

  Yes

  No

  N/A

Control Measures

• 7. Has a formal water services based risk assessment been completed?<br><br>Are there formal drawings of the entire network, and it these include the following:<br>• Isolation valves?<br>• Drain lines?<br>• Pressure reducing valves?<br>• Pressure relieving valves?<br>• Vacuum breakers and other components of the network?

  Yes

  No

  N/A

• 8. Has the boosting pump set(s) been sized and designed in order to:<br><br>• Cope with the highest demands?<br>• Ensure effective control of the filling operation following shut-downs or low-pressure events?

  Yes

  No

  N/A

• 9. Have the control system and pumps) been set to shut down, requiring manual reset, following a power cut or other event during which the output pressure is insufficient to reach the top of the building?

  Yes

  No

  N/A

• 10. Is a suitable procedure in place requiring manual restarting of the pump set(s)?<br><br>Does this include limiting the fill rate of riser?<br><br>Are written instructions provided detailing the procedures required?

  Yes

  No

  N/A

• 11. When pressure is less than that required to fill the riser:<br><br>• Has the boosting pump control unit automatic filling mode been disabled?<br>• If not where the pump(s) control unit incorporates an automatic filling mode, has this been set-up to ensure safe and effective operation and to prevent water hammer or surge?

  Yes

  No

  N/A

• 12. Has an escape of water event been clearly documented in an Emergency Response Plan or an Action Plan, developed for potential water damage?<br><br>Does this highlight what steps to take to stop any escape of water?<br><br>Does this include what damagecontrol/mitigation measures to take?

  Yes

  No

  N/A

• 13. Is a copy of the emergency Response/Damage Control Action Plan held on site and freely available to all relevant personnel?

  Yes

  No

  N/A

• 14. If a leak occurred downstream of the booster pump, would the boosted water supply system continue to pump water?<br><br>Has this been assessed?<br><br>If there are appropriate controls to prevent this, have they been tested?

  Yes

  No

  N/A

• 15. Has leak detection equipment or water flow analytic equipment been installed to help identify a leak or to help reduce the impact of water leaks?

  Yes

  No

  N/A

Maintenance

• 16. Is the boosted pump(s) and control equipment and associated infrastructure subject to regular:<br><br>• Inspection?<br>• Service and maintenance?<br>• Testing?<br><br>Is this based on the manufacturer's guidelines, learning from the installation and failure rates, etc.?

  Yes

  No

  N/A

• 17. Are suitable measures in place to control the risks of escape of fluid during service or maintenance?<br><br>Are there written procedures and steps to refill systems in a controlled manner following any maintenance work?

  Yes

  No

  N/A

• 18. Are any pressure reducing or relief valves inspected, maintained and tested?

  Yes

  No

  N/A
