- Page 9 User information EWE-FLEXORIPP Water Meter Pit Edition 01/2017 The water meter pit system is factory fitted with a PE adapter. The PE adapter is only used as a substitute for the water meter and is not suitable for operation. Information about the installation site The water meter pit should be located at an elevated position on the site or protrude a few centimetres above ground level if possible. The choice of pit size should be compatible with the frost-free installation depth of the pipe and is the sole responsibility of the user. The water meter pit demonstrates favourable behaviour against buoyancy because of its external shape. An essential requirement is that it is installed properly with gravel backfill and compaction in layers. The pit body has a waterproof design and the connection to the cover is impermeable to surface water. A soil engineering specialist should be consulted in areas where there is a risk of temporary flooding. Should there be flat-lying supply pipes (so-called summer pipes) downstream of the water meter pit, which have to be emptied before the start of the frost season, we recommend installing a special fitting in the pipe routing between the pit exit and the tapping point, e.g. an EWE garden valve in combination with an installation set. An EWE garden hydrant provides the same convenience in the case of an outdoor tapping point. The emptying of the downstream supply pipe in the pit body requires special care from a hygienic point of view. The water from the pipe must be pumped away immediately during the emptying phase and then the drain opening must be closed to prevent any possible contamination in the pipe network. Excavation and backfilling The water meter pit is delivered ready for installation and can be used in prepared ditches. The work required is the responsibility of the user.

Page 10: Installation
User information EWE-FLEXORIPP Water Meter Pit Edition 01/2017 Installation • Level out and compact the bottom of the trench evenly throughout. • Position the pit so that it is vertical and level. • Arrange for the foundations for the footprint of the pit to be dug in accordance with load class A15 or B125. • Arrow - Observe the flow direction when aligning the pit. • Flush the pipe before establishing the connections. • Establish connections between the connection sleeves of the pit and the pipe. • Observe the guidelines of the connection fittings manufacturer. Perform a leak test in accordance with the regulations. • Backfill the trench in the area of the water meter pit. • Support the connection pipes (inlet and outlet side) before the compac- ting. - Page 11 User information EWE-FLEXORIPP Water Meter Pit Edition 01/2017 • Install the water meter in accordance with section 4 “Maintenance and servicing”. • Install the pit cover in accordance with section 5 “Pit covers”. The pit may not be operated without a pit cover in accordance with section 5. The insulating cover is non load-bearing. The installation site and pit opening must be secured against unintentional CAUTION access during the installation period. Current information at: www.ewe-armaturen.de...
- Page 12 User information EWE-FLEXORIPP Water Meter Pit Edition 01/2017 Shortening the pit pipe The cylindrical, rib-shaped part of the pit can be shortened in 2.5 cm sections. At least 3 ribs need to remain to mount the cover frame and its seal. Frost protection through the planned installation depth must be taken into consideration. If shortened by more than 20 cm, the length of the lifting line must be reduced or the latter must be replaced. • Remove the cover if one is fitted. • Loosen and also remove the cover frame (if applicable). • Remove the cover frame seal (if applicable). • Remove the insulating cover.

Page 13: Operation And Use
User information EWE-FLEXORIPP Water Meter Pit Edition 01/2017 • Take the measurement to the surface. • When using the cover cap, makesure that the pit together with the cap prot- rude approx. 7 cm above the ground. • When using the A15/B125 pit cover, add its height of 7 cm from the first rib. • The pit pipe can be shortened in sections of 2.5 cm at the deepest point of the rib using a suitable tool (e.g. EWE- FLEXORIPP cutter). • A minimum of three ribs must remain. • Deburr the cut edge. • Deburr the first rib at its deepest point. • Install the pit cover in accordance with section 5 “Pit covers”. Operation and use A visual inspection of the water meter pit, the water meter pit fittings and the entire system must be made prior to putting it into operation. Functional check and leak test The entire system must be checked to ensure that it is working and has no leaks. -
Page 14: Maintenance And Servicing
User information EWE-FLEXORIPP Water Meter Pit Edition 01/2017 Pit security The pit must not be operated without a pit cover in accordance with section 5. The insulating cover is non load-bearing. The installation site and pit opening must be secured against unintentional CAUTION access during the installation period and during operation of the pit. A15/B125 pit covers must be locked with the enclosed screws. Frost protection The insulating cover fastened to the lifting line must be used. Frost protection must be ensured through the local installation, in particular by the right choice of installation depth. It is therefore the sole responsibility of the planning and contracting body to ensure the frost-free conditions in the pipe and pit. Maintenance and servicing The (ball) shut-off valves in the water meter systems are generally defined as maintenance fittings; they should therefore be actuated slowly in the case of maintenance (during opening and closing) when the tapping devices are closed. The fittings must be opened as far as they will go, i.e. by setting them to the fully open position. It is not permitted to restrict them. It is recommended that the shut-off valves on the water meter system are normally actuated at least once a year to ensure that they work and move freely. As a general rule, an annual functional check should be performed on the non-return flow valve. It is not necessary for plug-in non-return flow valves to be inspected annual- ly. These fittings must be changed with the regular replacement of the water meter, but within 10 years at the latest (EN806). The non-return flow valves are wear parts. A functional check can be carried out on models with a control screw that are already installed. - Page 15 User information EWE-FLEXORIPP Water Meter Pit Edition 01/2017 Meter reading and meter replacement • Remove the cover and insulating cover. • Pull out the water meter pit system with the aid of the lifting line. • Place the water meter pit system next to the pit opening. • Alternatively, the pit system can be fixed with the plinth on the pit frame. • Install and replace the meter taking account of the installation instructions of the water meter manufacturer. • Lower the water meter pit system slowly on the lifting line. • Close the insulating cover. • Fit the pit cover.
