Drain installation takes into account principles related to gravity, vacuum, grade, health hazards from biological agents, and resistance to functional failure.

This law seeks to bring an end to suction entrapment related injuries and deaths by incorporating consumer protection regulation of pool and spa drains.

It allows drainage of liquids but prevents entry from large solid objects, and thus acts as a coarse filter.

Disassembly of drain pipes can be an effective method of clearing severe blockages, especially if caused by the presence of a solid object.

[citation needed] Blocked drains, if left long enough, can develop into a health hazard as the presence of mold and bacteria increases.
