e City of Everett Permit Review CheckMate° Installation Procedure EYFREil5etu5: 610r Permit M 01/19M/2023 23 6:54:10 PPM 6. Preparation The CheckMate®Valve uses expantling damp(s)to exert pressure outwards on the walls of the salve to wedge it in piece within the pipe. The walls of the pipe should be clean and free of debris prior to installation. The valve should be inserted fully into the pipe so that no part of Me cuff or bill Wants outside the pipe. Ensure that the valve is not slanted at an angle with the bill pointing upwards or downwards. The valve centerline should be parallel to the pipe centerline. itleflexe Technologies recommends pinning the CheckMate°Vase on all installations. See below. Four pm-tlrilletl holes am provided in each expansion clamp. At least one clamp should be pinned. On exposed pipe, holes can be tlrilletl through the valve and pipe, ed and abolt runthrough should ld be used with a nut. For buried pipe, silicon or similar sealant shoultl be usetl to seal bolts. ]. Lubrication The outside of the valve can be lubricated with a water -based lubricant prior to inserting the valve into the pipe. R the taping procedure has been used, the surface of the tape can be lubricate to aid insertion. GWTIUN: Oo not use oetmieum-based lubricants on this product or an the vulcanized rubber tape. 8. Plumb Lines and Arrows The CheckMate° Valve arrives with a "top" arrow, "flow" arrow and plumb lines, marked in white, at the 12:00 and 6:00 position of the valve. Utilize this marking to orient the valve in the pipe, as well as to ensure the valve is oriented correctly in pipe section. 9. Valve Orientation The CheckMate' Valve must be installed in a horizontal pipe. Valves 4" —18" (nominal) are supplied with a single clamp. The clamp turnbuckle should be oriented at top dead center as tlelinatetl by the plumb line. Valves 20"-60" (nominal) are supplied with two clamps. The turnbuckles should be oriented 45-from the top center plumb line. The 72" is supplied with three clamps. The turnbuckle for one clamp to be at top center. The other clamps to be 45- to each side of top center. 10. Insertion Into Pipe Clamp to support the shape of Me cuff should be hand tight and should be Wended outward, but only tight enough to loosely keep the shape of the cuff during installation. CAUTION: If you spend the clamp excessively at this slap it will hinder or prevent the CheckMate"al being fully inserted into the pipe.
