Attention is drawn to national or local regulations and requirements. Plastics piping systems for hot and cold water installations — Polybutylene PB — Part 5: The design and selection of materials shall take into consideration the service conditions and water quality. Where these are not available national standards or local regulations should be used.

Figure 2. Vented potable water installations. Information and criteria about the reasonable choice of metal pipe material taking into account corrosion likelihood is given in EN to —5.

Unless otherwise specified in European Standards. Installation types A and B may be combined. The potable water installation shall be designed to: Closed potable water installations. Figure 3. All pipes and joints of a potable water installation shall be designed for a service life of 50 years taking into account appropriate maintenance and specific operating conditions.

The test pressure shall be at least 1. Surge pressures resulting from the operation of valves in fire extinguishing and fire protection systems which are operated no more than once a month for test purposes and otherwise only in the event of a fire are excluded from this requirement.

There shall be no cross connection of systems carrying water from different water suppliers or of different sources from one supplier. If not required in national or local regulations the sum of operation pressure and surge pressure should not exceed test pressure of the installation. See EN Lead pipes and -fittings shall not be used.

Pipe joints shall be permanently water-tight under the alternating stresses occurring in operation. Basically two different designs will be distinguished: Other materials and systems can be used if they comply with the general requirements given in 3. For the latter. Thread according to EN b Thread on transition fittings c See national regulations and standards d Corrosion risks have to be considered. Sockets with spigot ends according to EN Copper alloy compression fittings.

Pipes see EN Copper and copper alloy capillary fittings for soldering and brazing. Galvanized malleable cast iron fittings are normally used for jointing. Protective coatings and linings may be required. For push fit fittings see prEN For threaded ends see EN Fluxes containing chlorides. Hot dip galvanized malleable cast iron fittings according to EN Small copper connections to large stainless steel tanks should be avoided.

Only joints with fitness for purpose of the PE-piping system according to EN Socket fittings according to EN X - permissible not permissible Only joints with fitness for purpose of the PE-piping system according to EN Only joints with fitness for purpose of the PEpiping system according to EN X permissible - not permissible Pipes.

Hoses should not be longer than 2. In addition. This stop valve shall. A servicing valve shall be provided on the inlet connection to appliances e.

The supply pipes for each storey and those in the individual flats shall be capable of being shut off separately. This stop valve shall be installed either inside or outside the building in a position to which every occupier of the premises supplied has access.

Proof of compliance with this requirement shall be provided by the manufacturer. In every building or part of a building to which a separately chargeable supply of water is provided and in all premises occupied as a dwelling.

This stop valve shall be located in the main building as near as practicable to the exit point of the supply pipe to the other structure or if this is not practicable in the other structure itself as near as possible to the point of entry of the supply.

All hoses used instead of pipes and which are permanently under pressure shall comply with 3. The applicable test method should be agreed between the manufacturer and the customer. Elastomeric expansion joints shall have a minimum lifetime of 10 years when fitted according to manufacturers instructions.

The use of elastomeric expansion joints in a potable water system is only permitted if they have been suitably approved implying their adequacy of design and material. Pipes shall not be laid through drains or sewers. Pipework may be boxed in. Where a supply provides water to more than one building a riser shall be installed in each building.

In the case where less frequent use is made of the draw off capacity. Fire protection has to be maintained. Except where a pipe is installed in a sleeve. In a dwelling divided into a number of flats. If colour code is used for this purpose. Pipe runs to cold water taps within buildings shall not follow the routes of space heating or hot water pipes or pass through heated areas such as airing cupboards or.

Where pipes for hot and cold potable water are arranged one above another. Special measures e. Draining taps should be fixed over a drain or have provision for discharging the water to the nearest convenient point for disposal. The pipework within each building shall be connected to potential equalizing bars. Draw-off points for non-potable water shall be identified with the words "Non-potable water" or by a prohibition sign as shown in figure 1.

Water outlets shall only be placed in positions where there is a drainage system of sufficient capacity. A servicing valve shall be fitted upstream of.Their performances are related to the specific membrane characteristics and operating conditions nano filtration.
