Calibrate pilot control settings (pressure and flow, altitude valves, etc.) <br />d. Maintain and clean the strainers and valve body <br />e. Exercise the valves <br />f. Check the pilot tubing for leaks <br />g. Inspect pilot disc retainers <br />h. Confirm that the diaphragm assembly is properly functioning <br />Preferably, preventative maintenance should be accomplished without removing the valve from <br />the line. However, if removal of the valve is required, the Contractor shall notify City staff prior <br />to performing the work. Upon completion of inspection and maintenance services, the Contractor <br />shall also ensure all tags and/or reference markers on valves and appurtenances are up to date <br />with the most accurate information such as model number, serial number, etc. <br />In the event, the Contractor encounters outdated valves in need of replacement, the Contractor <br />shall recommend retrofitting old valves with up to date new valves that meet or surpass industry <br />standards. <br />Within ten (10) business days of completing maintenance services on the City's Cla-Val's, the <br />Contractor shall provide a service report to the City of Santa Ana. The Contractor shall follow up <br />with City personnel and notify City staff on any issues encountered in the field regarding requiring <br />additional parts. The Contractor shall state all findings, if any, along with a proposed scope of <br />work and complete cost estimates for any recommended equipment repairs and/or replacement. <br />II. REPAIR SERVICES (BID ITEMS 4-9) <br />The Contractor shall repair or replace any parts of the valve found to be worn or otherwise in <br />need of replacement. All internal parts of the valve shall be cleaned of mineral deposits prior to <br />reassembly of the valve. When required (typically every 5 years), complete valve <br />rebuilds/rehabilitations should be performed in which the main valve and its respective pilot <br />controls are cleaned internally, all rubber parts are replaced, and all metal parts replaced where <br />needed. All repairs and rehabilitations shall be made in accordance with Cla-Val guidelines and <br />as directed by the City. <br />The Contractor shall be factory trained in maintaining all piloting systems offered by Cla-Val and <br />shall fix/repair all piloting systems in accordance with Cla-Val guidelines and as directed by the <br />City.
