24.2.2.3 Alarm
An alarm system that sounds when the diverter valve directs
SANITARY SEAWATER or POTABLE WATER from the heat
exchanger.
25.0 Recreational Water Facilities Water Source
25.1 Filling System
Provide a filling system that allows for the filling of each RECREATIONAL
WATER FACILITY with SANITARY SEAWATER or POTABLE WATER.
For a compensation or make-up tank supplied with POTABLE water, an overflow
line located below the fill line and at least twice the diameter of the fill line is an
acceptable method of BACKFLOW protection as long as the overflow line discharges
to the wastewater system through an indirect connection. If make-up water is
introduced into the RECREATIONAL WATER FACILITY directly, the water should
be at the same level of HALOGENATION and PH as the RWF before entering the
RECREATIONAL WATER FACILITY.
Avoid BLIND LINES in the water systems of recreational water facilities.
25.2 Compensation or Make-Up Tank
Where make-up water is required to replace water loss due to splashing, carry out,
and other volume loss, install an appropriately designed compensation or make-up
tank to ensure that ADEQUATE chemical balance can be maintained.
25.3 Combining Recreational Water Facilities
No more than two similar RECREATIONAL WATER FACILITIES may be
combined.
CHILDREN’S POOLS and BABY-ONLY WATER FACILITIES must not be
combined with any other type of RWFs.
25.4 Independent Manual Testing
When combining RECREATIONAL WATER FACILITIES, provisions must be
made for independent manual water testing within the mechanical room for each
RECREATIONAL WATER FACILITY.
25.5 Independent Slide Recreational Water Facility and Adult Swimming Pool
An independent slide RECREATIONAL WATER FACILITY and an adult
SWIMMING POOL may be combined provided that the water volume added to the
slide and the slide pump capacity are sufficient to maintain the TURNOVER rate as
shown in section 29.10. Any other combinations of RECREATIONAL WATER
FACILITIES will be decided on a case-by-case basis during the plan review.
