EN 16713-2:2016 (E) 5 1 Scope This European Standard specifies requirements and test methods for circulation systems and is applicable to equipment used in domestic swimming pools and designed for the circulation of water (introduction and/or extraction). This standard applies for swimming pools as defined in EN 16582-1 and will be read in conjunction with it. This standard does not apply to: — pools for public use covered by EN 15288-1; — spas for domestic or public use; — paddling pools according to EN 71-8; — pre filtration; — natural and nature like pools. NOTE For filtration systems see EN 16713–1 and for treatment systems EN 16713–3. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Where applicable, the volume of the overflow tank shall be included with the volume of the pool to give the total volume in the system. The total volume in the system is the volume used in all calculations. The circulation system will ensure the greatest possible mixing of the water in the pool basin in order to provide a uniform distribution of chemical treatment and heat, making sure fine debris are kept in suspension as long as possible and that there are no “dead areas” where water movement is zero. The filtration system shall have a sufficient nominal flow rate to allow the total volume of water contained in the pool to be recycled in no longer than 8 h. The filtration system nominal flow rate Q is calculated: =TOVQT (1) where Q is the filtration system nominal flow rate in m3/h; SIST EN 16713-2:2016
EN 16713-2:2016 (E) 7 V is the pool volume in m3; TTO is the turnover time of the pool volume in h 4.3 Extraction of pool water 4.3.1 General The majority of the pollution within a swimming pool is found in the top layer of the pool water and therefore good surface water removal during pool operation is essential for efficient filtration and treatment of the water. Other systems can also be used to help the efficiency of the removal of the complete water volume (e.g. bottom main drain, etc.). 4.3.2 Overflow channel 4.3.2.1 Dimension of overflow channel and channel drains The cross section of the overflow channel shall be designed adequately to achieve sufficient temporary water storage. If the channel is to be used as a balance tank, it should be sufficiently sized to accommodate the effective volume required (see a) to d) in 4.3.2.3). The dimension and numbers of channel drains shall be designed according to the expected: a) water displaced by bathers; b) amount of water created by waves; c) nominal filtration system flow rate; d) water and air based pool features. The dimension of the channel drains shall be sufficient to allow water flow without pressure (under gravity only) and to minimize noise. The internal surface of the overflow channel shall be easily cleaned to prevent the build of solid, bacteria biofilm, etc. NOTE When overflow channels with a continuous slope are installed, the water can be extracted through one or more sufficiently designed channel drains at the lowest point. 4.3.2.2 Overflow channel cover The overflow channel cover shall be designed to avoid entrapment for fingers and toes, be capable of taking the design flow of water and also be able to support the weight of the bathers. The cover shall collect the flow of water. National safety regulations shall also be considered. The cover should be removable for maintenance and cleaning. Where the cover is not removable, an adapted cleaning system shall be provided. 4.3.2.3 Water balance tank The size of the water balance tank should consider the: a) amount of water displaced by bathers, or any submerged equipment; b) amount of water created by waves; c) losses of water due to splashing, evaporation, filter backwashing; d) minimum water level in order to prevent air suction into the pump. SIST EN 16713-2:2016
EN 16713-2:2016 (E) 8 NOTE Water for filter backwashing can be also taken from the pool. The water balance tank should have: — access hatches to allow for cleaning and maintenance. The internal finish of the tank shall be easily cleaned so as to prevent the build-up of solids, bacteria etc.; — venting or connection to the atmosphere; — overflow drain; — connection point for filling up water. 4.3.3 Skimmer 4.3.3.1 General With a skimmer, the water will be removed of one or more positions at the pool. The number of skimmers depends on, but is not limited to, the following: — surface area; — pool shape; — skimmer opening size; — nominal flow rate. A flow rate ratio of approx. 2/3 through the skimmers and approx. 1/3 through the bottom drain(s) or additional outlets is recommended. The hazard of suction at the main drain(s) according to 4.4 shall be considered. 4.3.3.2 Installation of skimmers When installing more than one skimmer, the skimmers shall be installed to ensure balanced flow in each skimmer. 4.3.3.3 Skimmers in outdoor pools The positioning of skimmers should be opposite to the main wind direction. 4.3.3.4 Construction requirements In case the skimmer lid can be walked on, the lid shall withstand the mechanical load. The skimmer lid shall be installed securely to prevent unintentional removal. 4.3.4 Main drain The main drain shall be used in combination with surface water extraction for filtration purposes. One or more main drains can be installed in a pool. To use the main drain as pool drain it shall be installed on the deepest area of the basin. 4.4 Risk of suction entrapment 4.4.1 General Suction devices shall be designed and installed so as to minimize the potential for entrapment of the user. SIST EN 16713-2:2016
EN 16713-2:2016 (E) 9 Water speed at fully submerged suction outlets should be
¶ 0,5 m/s. Hair entrapment tests shall be performed on suction devices according to 5.3. Safety requirements a) to c) are not applicable to: — skimmers, because they are vented (see 4.4.3) and partly above the water level; — integrated swim jet systems, because the users are pushed away from the outlet, as defined in 3.3 by the action of the inlet. Additionally at least one of the following requirements shall be met: a) multiple suction outlet system designed in such a way that: 1) a minimum of two balanced and functioning suction outlets; 2) the distance between the nearest points of the perimeters of the devices shall be as large as possible with respect to the size of the pool and the design of suction outlets, but with a minimum of 1 m to ensure the appropriate level of safety from entrapment; 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 cannot cover more than 50 % of the opening; or 2) raised grilles domed opposite to the flow direction, with prevalent peripheral suction. The height of the dome shall be at least 10 % of the main dimension; or 3) single grilles with a surface of the area circumscribed to the suction openings
· 1 m2 (see Figure 1); or
Figure 1 — Identification of the area circumscribed to the suction openings c) any suitable designed outlet suction grille(s) that complies with the obstruction tests according to 5.4. In addition to the requirements in a) to c), a vacuum release system may be provided. 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: SIST EN 16713-2:2016
EN 16713-2:2016 (E) 10 — the existing suction outlet shall be retrofitted with a grille conforming to b), or c); — one or more additional suction outlets shall be provided as in a). Vacuum release systems typically respond to a blockage of a single outlet by: — releasing the vacuum by turning the pump off and introducing air; — drawing out water present in a vent tube to allow air penetrates through this tube towards 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 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. 4.4.2 Suction chamber for floor and wall water outlets Manufactured or field built floor and wall water outlets shall have a suction chamber with dimensions as shown in Figure 2.

The number of inlets should be sufficient to take 100 % of the nominal flow rate of filtration system. The water speed at pool inlets shall be
¶ 15 m/s, except for vertical injection from the swimming pool floor in water depth < 700 mm, where it shall be
¶ 2 m/s. The number and location of the inlets shall ensure an equal and efficient water distribution in order to avoid water stagnation taking into account the following: a) effective water volume of the pool and pool size; b) pool shape; c) outlet location; d) nominal flow rate of filtration system. To verify the water distribution the dye test according to 5.1 may be applied if necessary. 4.5.2 Introduction of pool water at reduced filtration flow rate In case of reduced filtration flow rate e.g. during night time when the pool is not used, the introduction of pool water into the pool shall still be sufficient to ensure the maximum turnover time in 4.2. The validation at reduced flow rate may be verified according to 5.1 if necessary. 4.5.3 Air and water operated leisure feature 4.5.3.1 Introduction of water and/or air from the floor Features incorporating the introduction of water and/or air under pressure from the swimming pool floor shall not be installed in depths of less than 700 mm unless: a) the vertical water speed is

EN 16713-2:2016 (E) 12 4.5.3.2 Positioning of water features Fountains shall not be an obstruction hazard. Special attention shall be paid to interferences between the possible paths of the users in and around the pool and the design and position of the fountains. Wherever the risk of impact is foreseeable, the water effect shall not hide the fountain structure, or it shall be made obvious (see Figure 4). Dimensions in millimetres
Key 1 walkable floor Figure 4 — Fountains — Horizontal and vertical clearances Generally, protruding jets should be avoided on the swimming pool wall, however in the case of overhanging counter-current or filtration units, protruding jets are allowed as long as they are part of a visible obstacle in the pool. 4.5.4 Other dangers The manufacturer shall provide recommendations for maintenance and cleaning of the air and water operated leisure features. 4.6 Pipe work The pipework and fittings used in any circulation system should be sized to take the nominal flow rate of filtration system and to minimize frictional head losses. The material should be non-corroding and in general terms suitable for the head pressure in the system and the water speed should not exceed 3 m/s with in the circulation pipe work at the pressure side. This is a maximum water speed at the pressure side, lower speeds are encouraged and will result in added energy savings. To avoid a potential cavitation risk it is recommended that water speed at the suction side of the pump shall be lower than the water speed at the pressure side taking into account pump suction behaviour and manufacturer's recommendations. SIST EN 16713-2:2016
EN 16713-2:2016 (E) 13 The maximum water speed does not apply to: — water inlet connections; — water based attraction connections; — pipework and connections for water leisure features (unless specified by the manufacturer). Pipework and fittings used in swimming pools are generally used in other fluid applications; they shall be suitable for the application and be covered by national standards. When used underground, the pipework shall be compatible with its environment. Pipework should be installed at a certain depth below ground level depending on climatic conditions (soil freezing) and national standards/regulations. The pipes (whether rigid or flexible) shall be fully supported and shall be surrounded by non-compactable protective material to prevent any damage. All above-ground pipe runs shall be adequately supported. It is not acceptable to rely on items of equipment for support. All underground pipework shall be pressure tested (if applicable) for soundness before backfilling and a test report issued as proof. Annex A provides a possible pressure test procedure, which however does not supersede any national regulations. A second test shall be carried out after backfilling and before any concrete and/or finishes are installed to make sure there has been no damage to the pipework during compaction. The pressure tests shall be carried out fo
