A spa pool constructed after December 25, 2009;(b)

Intentionally left blank —Ed.(a)
Every spa pool must have an easy and effective means of draining the pool.(b)
Main drain and submerged suction outlets must be designed with sufficient open area that the maximum velocity through the cover does not exceed the cover’s listed flowrate. Drains and suction fittings must be installed to minimize tripping, toe stubbing and scrape hazards.(c)
All hardware and fittings must be supplied by the manufacturer and installed according to the manufacturer’s directions.(d)
Broken or missing grate fittings. If the pool operator finds that a suction fitting is broken or missing, the operator must close the pool immediately, shut down the recirculation system and remain closed until the fitting has been replaced.(3)
New construction. Main drain and submerged suction fitting systems must provide entrapment, hair entanglement and evisceration protection.(a)
Main drains and submerged suction fittings and sumps must be compliant with the requirements of ANSI/APSP-16 Suction Fittings for Use in Swimming Pools, Wading Pools, Spas, and Hot Tubs (2011). The cover must be labeled and include; “VGB 2008,” the logo of the third party listing agency, the standard for which it was tested, the gallons per minute flow for which it was approved and the location it is to be placed.(b)
The spa licensee must maintain any documentation concerning the main drain or submerged suction fitting.(c)
All submerged suction fittings must be installed with a sump designed and approved by the manufacturer for that outlet cover.(d)
All field built sumps must be designed by an Oregon registered engineer and must be built so the opening of the suction pipe is no closer than 1.5 times the pipe’s inside diameter from the bottom of the listed suction cover/plate.(e)
Main drains and submerged suction fittings must be separated by at least three feet (915mm)(measured from the main drain connector pipe centerlines) between the furthest fittings, or be on separate planes, placed so the floor and wall suction fittings cannot be easily blocked at the same time.(A)
The outlets must be sized to handle an equal portion of at least 200 percent of the recirculation flow.(B)
The outlets must be installed so that they cannot be isolated from one another; no intervening valves.(C)
The piping going back to the pump must be located in the hydraulic middle of the connector piping, and must be the same size as the connector piping.
