Upon arrival I found packaged geo system locked out on Low Pressure. During diagnostics I reset system and checked operation. Found low water flow (EWP 65psi, LWP 48psi). Verified Coax Coil is not where restriction is so I went to Inline water filter, which was black. Opened up relief on the bottom and no water came out. Shut off all water flow and removed inline filter from piping. Took outside and cleaned out by hooking up bottom relief to garden hose and using back pressure to clear restriction. Flushed out filter as well but found that filter screen has a few holes in it. Quoting customer to replace Inline filter because holes are causing debri to clog water flow, 1.5inch filter. Unit seems to be operating normally once Filter was cleaned. System started by satisfying hot water then switched over to heating and satisfied thermostat. **1.5inch Mesh 60 Inline Filter** Need to replace the 1.5inch Inline filter screen, current one has holes.
