<br />" <br />; ~ <br />"J <br /> <br />u <br /> <br />Appendix B <br /> <br />Test Protoeol- Fill Valve Integrity Te5t <br /> <br />This requirement shall apply to all fill valves that are not otherwise classified as pilot valves,. <br /> <br />Must conform to both of the following requirements (I and 2): <br />I. !:,onsi$tent Water Level <br /> <br />Purpose of Te5t: To determine whelher or not the fill valve shuts off at a consistent water <br />level in a toilet tank independent of any change in inlet water supply pressure. <br /> <br />Te5t Procedure: <br /> <br />a. Inslall the fill valve in the toilet tank provided, install the tank on a leveled test stand, and <br />adjust the water level per the manufacturer's recommendation at an inlet water pressure <br />of 20 PSI +/- 2 PSI or at the manutictunlt's recommended minimum pressure as noled in <br />the product literature and product packaging. <br />b. Fluah the tank 10 verilY and mark: water level after completed refill. <br />c. Increase the inlet water pressure to 60 PSI +1- 2 PSI. <br />d. Flum the tank. <br />c. Measure any difference in water level after completed refill. <br />f. Repeat stepa c-d-e utilizing 80 PSI +1- 2 PSI inlet water ~5Ure. <br /> <br />Performance Reqairement: The fill valve shall shut off at the same water level +1- !oS incb <br />for all three inlet water presaurea. In addition. water mall not enter the overflow tube or flow <br />out of the tank at all three inlet pressures. <br /> <br />2. Sbutoff Intellritv with Increased Water Pressure <br /> <br />Purpose of Test: To determine wbether or not the fill valve shuts off at a consistent water <br />level in a toilet tank independent of changes in inlet water supply pressure. <br /> <br />Teu Procedure: <br /> <br />a. Install the fill valve in a toilet tank and adjust the water level per the manufacturer's <br />recommendation at an inlet water preSSllle of20 PSI +/- 2 PSI or at the manufacturer's <br />recommended minimum pressure as noted in the product literature and product <br />packaging. <br />b. Flush the tanJc to veriJy and mark water level after completed refill. <br />c. Increase the inlet pressure to the fill valve from 20 (or recommended minimum pressure) <br />to 60 PSI, then to 80 PSI at a rate ofless than 10 PSI per second. <br /> <br />Performaace Requirement: The water level shall remain at the initial marlc +/- !oS inch. In <br />addition, water shall not enter the overflow tube or flow out of the lanlc. <br /> <br />Loa Angeles Department of Water 4t Power <br /> <br />Revised: 1111612005 <br />
