Valve Replacement & Repair

LI 001: BLDG 10 (Water Treatment Facility) Remove, inspect, rebuild and reinstall the two existing Peerless 4-inch turbine water pumps. Minimize disruption to water service during this work by working on one pump at a time. Repairs/rebuilds may include new bearings, seals, packing and anything else determined to be needed. Once rebuilt, reinstall and test each pump for proper operation., 1, JA; LI 002: Interconnection Vault Replace the existing spool piece where the water line exits Building 10 and where the chlorination injection occurs. This line is corroded and does not have any ball valves to allow replacement of the chlorine injection site. Replace this spool piece with a new stainless steel (SS) spool piece with two injection quills and two new SS ball valves. Install spool piece through the wall and use a uniflange to bolt it to the existing 4-inch elbow outside Building 10. Fill around the wall penetration with foam and hydraulic cement. This task will be performed during off hours/down days to minimize disruption to base personnel., 1, JA; LI 003: Interconnection Vault Replace the existing 10-inch fire relief valve (Model Zurn ZW205FP) with a 10-inch pressure reducing valve (OCV Model 127-380X2F-190 or equivalent). Make all connections as needed for the new valve, check for leaks, and set the activation pressure as directed by ANG., 1, JA;
