- Piping must be of the correct size to maintain the required supply pressures and volume flow under varying conditions.
- Installed piping must be properly purged and leak-tested, in accordance with applicable codes and standards.
- Use an approved pipe sealant or joint compound on all threaded fittings, to reduce the possibility of leakage.
