All suction outlets must have
correctly installed, screw-fastened
covers in place.
• At least two hydraulically balanced main drains
for each pump suction line. Main drains must be
at least three feet apart, nearest point to nearest
point.
• The pump suction system must provide protection
against the hazard of suction entrapment or hair
entrapment/entanglement. All suction outlet covers
must be maintained. They must be replaced if
cracked, broken, or missing.
• If 100% of the pump's flow comes from the main
drain system, the maximum water velocity in the
pump suction hydraulic system must be six feet
per second or less even if one main drain (suction
fitting) is completely blocked.

• The system must not be able to operate with the
pump drawing water from only one main drain
(that is, there must be at least two main drains
connected to the pump whenever it is running.)
However, if two main drains run into a single
suction line, the single suction line may be
equipped with a valve which will shut off both main
drains from the pump.
