• All components shall be made of non-toxic materials <strong>and</strong> must be reasonably resistant to<br />
corrosion under operating conditions.<br />
• Components must be strong enough to be able to withst<strong>and</strong> pressures 150 % of normal<br />
operating conditions.<br />
• Piping must be installed in such a manner that they do not pose a hazard to the users.<br />
• Pipes must comply with the following sizes <strong>and</strong> fl ow rates show in the following table,<br />
unless accompanied by a hydraulic design:<br />

The total dynamic head of the reticulation system shall be calculated. In the absence of any calculations<br />
the following table may be used:<br />

38100 - 45720 80<br />
Beyond 45720 mm Calculations are Required<br />
PUMPS AND MOTORS<br />
Pumps <strong>and</strong> motors are to be installed on each water circulation system <strong>and</strong> shall conform to the<br />
following:<br />
• Pumps must be sized to meet but exceed the fl ow rates required for fi ltering against the<br />
total head developed by the complete water circulation system.<br />
• Pumps must be sized to comply with the required turnover rates.<br />
Swimming<br />
• All equipment must be readily <strong>and</strong> easily accessible for inspection, maintenance <strong>and</strong> repair.<br />
When pumps are installed below the waterline, valves must be installed on permanently<br />
connected suction <strong>and</strong> return lines. The valves must be removable when required.<br />
