NOTE 1 Frequency of testing should be determined by risk assessment
When retrofitting existing installations that have a single suction outlet which does not comply with the
requirements of this clause, then the following actions are required:
— the existing suction outlet shall be retrofitted with a grille conforming to b), or;
— one or more additional suction outlets shall be provided as in a) !."
!deleted text"
In addition to the requirements in a) to c), a vacuum release system may be provided
Vacuum release systems typically respond to a blockage of a single outlet by:
— releasing the vacuum by turning the pump off;
— drawing water out of a vent tube to allow air into the suction system;
— mechanically operating valves to reverse flow through the suction outlet(s);
— opening a valve to atmosphere to cause a pump to lose prime
All vacuum release systems shall be tested on outlets which meet the structural integrity and design
requirements for grilles given earlier in this standard
NOTE 2 These devices/systems are not considered “fail safe” systems as there is no known suction vacuum
release system that will completely protect against all outlet entrapment hazards Presenting Vacuum Release
Systems as “fail safe” systems would promote a false sense of security among the users of these devices/systems
Safety requirements a) to c) are not applicable to:
— skimmers, because they are vented (see 4.6.3) and partly above the water level;
— integrated swim jet systems, because the users are pushed away from the outlet by the action of the
inlet
NOTE 3 It is recommended to install at the deck an accessible general emergency switch for the pumps level
4.6.2 Sumps for floor and wall water outlets
Manufactured or field built floor and wall water outlets shall have a sump with dimensions as shown in Figure 2
Key
a indicates suggested sump configuration
D inside diameter of the pipe

Skimmers shall fulfil all the general entrapment requirements in accordance with EN 13451-1; otherwise they shall be subjected to a specific risk assessment

When retrofitting existing installations that have a single suction outlet which does not comply with the
requirements of this clause, then the following actions are required:
— the existing suction outlet shall be retrofitted with a grille conforming to b), or;
— one or more additional suction outlets shall be provided as in a) !."
!deleted text"
In addition to the requirements in a) to c), a vacuum release system may be provided
Vacuum release systems typically respond to a blockage of a single outlet by:
— releasing the vacuum by turning the pump off;
— drawing water out of a vent tube to allow air into the suction system;
— mechanically operating valves to reverse flow through the suction outlet(s);
— opening a valve to atmosphere to cause a pump to lose prime
All vacuum release systems shall be tested on outlets which meet the structural integrity and design
requirements for grilles given earlier in this standard
NOTE 2 These devices/systems are not considered “fail safe” systems as there is no known suction vacuum
release system that will completely protect against all outlet entrapment hazards Presenting Vacuum Release
Systems as “fail safe” systems would promote a false sense of security among the users of these devices/systems
Safety requirements a) to c) are not applicable to:
— skimmers, because they are vented (see 4.6.3) and partly above the water level;
— integrated swim jet systems, because the users are pushed away from the outlet by the action of the
inlet
NOTE 3 It is recommended to install at the deck an accessible general emergency switch for the pumps level
4.6.2 Sumps for floor and wall water outlets
Manufactured or field built floor and wall water outlets shall have a sump with dimensions as shown in Figure 2

a indicates suggested sump configuration
D inside diameter of the pipe
