EN 13451-1:2011, Table 1. 4.6 Risk of suction entrapment 4.6.1 General Suction devices shall be designed and installed so as to reduce the potential for entrapment of the user. Water speed at outlets shall be
¶ 0,5 m/s. #Additionally at least one of the either a), b) or c) shall be met: a) multiple suction outlet system designed in such a way that:$ 1) a minimum of two functioning suction outlets per pump are installed; 2) the distance between the nearest points of the perimeters of the devices is
· 2 m; 3) if any one of the suction outlets becomes blocked, the flow through the remaining suction outlet/s shall accommodate 100 % of the flow rate. b) #in case of suction outlet systems with only one grille, the grille shall be designed in such a way that either$ 1) one user can not cover more than 50 % of the opening; #or$ 2) raised grilles domed opposite to the flow direction, with prevalent peripheric suction. The height of the dome shall be at least 10 % of the main dimension. Obstruction test are available (for an example see Annex A); #or$ SIST EN 13451-3:2011+A3:2016

Figure 1 — Identification of the area circumscribed to the suction openings c) a gravity feed tank. 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. SIST EN 13451-3:2011+A3:2016

¶ 30 kPa. For water speed test see Annex B. 4.7.3 Influence of features on the users The introduction of water and/or air under pressure shall not compromise the safety of the users (e.g. by impact against obstacles or the pool wall). Features shall not operate at full pressure immediately; they shall build up to their full pressure over a period of time, sufficient for the users to become aware. 4.8 Stream channels and rivers 4.8.1 General The speed of the water and the path of stream shall not compromise the safety of a user entering or exiting the feature. The feature shall be designed to avoid unintentional collisions, which can cause hazards for the users. NOTE The different body masses and buoyancy of users should be considered as they can affect the action of any particular feature. The average speed of the water in the cross section of the stream channel shall be
¶ 3,5 m/s. The water depth in a stream channel shall be between 600 mm and 1 350 mm. The need of supervision of a stream channel shall be considered by a risk assessment according to EN 15288-1. 4.8.2 Other swimming pool components installed in a stream channel To prevent risks of impact and/or entrapment caused by involuntary movement of the users, special attention shall be paid to t
