(1) If a flume pump intake is in a plunge pool or in a swimming pool, it shall be located away from normal water slide user traffic areas. To prevent suction entrapment at the flume pump intake, one of the following designs shall be used:

(a) Multiple intakes may be used. Intakes shall be at least three feet apart. The intakes shall be covered with grates or other protective covers designed to prevent user entrapment. Water velocity through the intake covers shall not exceed one and one-half feet per second; or

(b) The pump intake for the water slide shall have an area of at least 342 square inches.

(2) An intake cover shall be designed to prevent user entrapment. It shall be in place at all times and it shall be securely fastened to the pool or to the intake pipe so it cannot be removed without specific tools.

(3) Water slide pump intakes must meet the requirements of the Virginia Graeme Baker Act, 15 USC 8001-8005 and ASME A112.19.8 (2007).
