3 Opening Pressures Opening pressure [mmh2o /inh2o] is the difference between the water level upstream and the water level downstream in the submerged case and to the invert of the pipe in the open air case. The opening pressure data presented in the technical specifications is measured with reference points according to Fig.1. Testing of the opening pressure is performed at room temperature. Head Loss The head loss diagram presents an empirical model with test data from a third party institute. The reference points for the head loss tests are the same as the horizontal opening pressure. The head loss presented includes all head loss associated with the WaStop installed in an outlet either open air- or submerged outflow. In the case when the head loss of a particular outlet is known before the installation this head loss could be subtracted from the head loss presented in the technical specification for an accurate estimate of the head loss for the outlet after installation of a WaStop check valve. For more information about head loss contact Wapro. Maximum Flow Velocity Maximum flow velocity is a recommendation that yields the longest service life. Both velocity and volume flow refers to the flow in the pipe in which the WaStop is installed. Since the flow area of the WaStop is slightly smaller than the pipe, the actual max flow velocity through the WaStop is higher than the max flow velocity stated in the technical specification. If an application demands higher flow than stated in the technical specifications contact Wapro. h h Figure 1. Reference point opening pressure horizontal and vertical.

5 WASTOP INLINE CHECK VALVE SPECIFICATION Revised: 12/02/ PRODUCTS 2.1. Function The check valves shall be designed to operate in installations using flanges, flat irons, slide muffs, joint couplings or custom made brackets. The check valve should be able to be installed on an inlet, or outlet, vertically, horizontally, inside existing pipes, or between two pipes. The housing of the valve should be of stainless steel and less than or equal to 3mm (1/8 ) thick to minimize the reduction of the flow area or PVC/PE. The membrane should be conical and should be attached to the housing with bolts or rivets along the top of the membrane, and the outlet side of the housing allowing maximum flow through the membrane. The check valve should have a pulsating flow, opening and closing at the specific levels specified in the technical specification. When the pressure on the upstream side of the valve exceeds the opening pressure the valve will open and allow flow through the valve. At a pre-determined pressure the valve will close leaving a pre-determined level of water upstream and prevent the upstream pipe drying out Installation Installation shall be conducted according to the manufacturers written instructions. All valves shall be marked with a unique serial number and flow direction reference Manufacturer All valves shall be of Wastop type and manufactured by Wapro AB, Sweden. Manufacturers name, model number, description and serial number shall be marked on the check valve Construction Housing/Tube Rolled sheet metal or press detail, (EN1.4301/AISI 304 or EN1.4404/AISI 316) Cut and lathed (PVC/PE) Membrane Polyurethane (PU) moulded eccentric conical membrane Silicone (MVQ) pressure moulded conical membrane Fixation material Wapro AB Munkahusvägen 103 S Karlshamn Sweden Tel: Fax: wapro@wapro.com Website: Reg.no VAT no SE Office: Karlshamn Sweden

17 ENGLISH CONGRATULATIONS ON YOUR PURCHASE OF THE UNIQUE PATENTED WASTOP INLINE CHECK VALVE. WaStop s unique construction prevents backflow in pipe networks. It can be installed in minutes either in existing pipes or manholes, and gives a reliable protection against high water levels, flotsam, gases, salt water, insects and small animals. SAFETY FIRST When installing a WaStop check valve please ensure that all safety precautions are taken. Wapro AB accepts no responsibility for incorrect installation or the improper use of this product. Incorrect installation can cause injury, reduce the valve lifetime or damage other mating pipe products. Please read the following information before installing the WaStop check valve. If you have any questions regarding installation please call your local WaStop reseller. STORAGE The WaStop check valve should be stored in a cool dry location with good ventilation. The valves should not have anything inserted into either end touching the membrane during storage. Don t drop, put undue pressure upon, or twist the pipe or membrane as damage may occur. The smaller dimension valve should be stored in the box they were delivered in. Larger valves should be stored in a safe location where tampering cannot occur. Avoid unnecessary exposure to light and chemicals. Store all WaStops in a vertical position with the end of the cone up. If this is not possible ensure the housing of the valve is supported to ensure ovality does not occur. TERMINOLOGY Flow direction: Normal direction of flow Existing pipe: An existing pipe into which WaStop will be inserted. Joint coupling: A flexible coupling joining the existing pipe and the WaStop. Expansion bolt: A bolt having an attachment that expands as the bolt is driven into a surface. Rubber seal: A seal that ensures no leakage between the inside of the existing pipe and the WaStop. Back pressure: The fluid pressure exerted against the valve. Usually measured in feet or meters of fluid above the invert of the pipe. Membrane: The elastomer conical membrane inside the WaStop pipe. WaStop pipe: The outer casing (housing) of the WaStop membrane. Wapro AB Limited Warranty Wapro will remedy defects in material and/or workmanship in any new Wapro valve for a period of two (2) years from the documented date of purchase so long as the valve has been used in accordance with Wapro s instructions and recommendations and under normal operating conditions. The warranty does not cover damage to the valve caused by external mechanical forces, such as interference from humans, animals or machines, nor is the warranty valid if the valve has been modified or altered in any way post-production. Furthermore, the warranty is not valid (a) if the valve is damaged due to exposure to high concentrations of chemical substances, (b) if the valve is damaged due to pressure surges and/or vacuum within the valve, (c) the warranty is invalid if flow velocity exceeds 2m/s through a standard WaStop, or 4m/s through a high pressure kit adapted WaStop, and (d) if malfunctions are caused by other equipment. To request warranty service, the buyer should contact the WaStop dealer where the valve was purchased within a reasonable time after discovering any defects. The valve serial number must be quoted in the case of a warranty claim. Wapro s liability is limited to the replacement or repair of the defective valve. Wapro will not assume costs incurred for removal of defective valves or subsequent installation of replacement valves. Furthermore, Wapro will not assume transportation costs of damaged valves or replacement valves. Wapro warrants that repaired or replaced valves are covered for the greater of either the remainder of the original valve warranty or 90 days. THE WARRANTY EXPRESSED ABOVE SHALL BE IN LIEU OF ANY OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT WHICH ARE EXPRESSLY DISCLAIMED, AND IS IN LIEU OF ANY AND ALL OTHER OBLIGATIONS OR LIABILITY ON WAPRO S PART. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, UNDER NO CIRCUMSTANCES WILL WAPRO BE LIABLE TO BUYER FOR ANY INDIRECT, INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES (INCLUDING ANY DAMAGE FOR LOSS OF REVENUE OR PROFIT), OR OTHERWISE ARISING OUT OF OR IN CONNECTION WITH FURNISHING OF THE VALVES, PARTS OR SERVICE HEREUNDER, OR THE PERFORMANCE, USE OF, OR INABILITY TO USE ANY OF THE VALVES, PARTS OR SERVICE, OR OTHERWISE, WHETHER BASED IN CONTRACT, WARRANTY, TORT, INCLUDING WITHOUT LIMITATION, NEGLIGENCE OR ANY OTHER LEGAL OR EQUITABLE THEORY. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE REMEDIES SET FORTH IN THIS LIMITED WARRANTY SHALL APPLY EVEN IF SUCH REMEDIES FAIL THEIR ESSENTIAL PURPOSE.
