(b) Prohibited connection.
Secondary roof drain systems may not be connected to primary roof drain systems.
All secondary roof drain systems shall discharge in accordance with Table 382.38–1.
Except for exterior loading dock drains, traps
are required for exterior drain inlets located within 10 feet of an air inlet, door or openable window.
A foundation drain that discharges by gravity to a storm sewer shall be trapped. The trap shall be provided with cleanouts.
A trap receiving clearwater shall be vented in accordance with s. SPS 382.31
. Vent piping for a clearwater drain system may not be connected to a vent system serving a sanitary drain system or chemical waste system.
Vents serving a solid covered sump shall terminate a minimum of one inch above finished floor.
An operation and maintenance plan shall be implemented for all stormwater plumbing systems for drainage areas of one or more acres that are installed on or after December 1, 2004.
