Installed 20” C/S whole house filters. Housing for the filters came off with no issues. **Filter change took so long because I had to wait around for the filters arrive, they were not in the pump house when I arrived at the home** When I received the filters I realized that the homeowner purchased 3 20” filters and no 10” filters. Could not replace the 10” filter this time and I didn’t have one on my truck. Homeowner will have to purchase the correct filter. Added on $59 dispatch fee because I have to go pick the filters up from the homeowners house myself. Sent copy of todays invoice to Hopes email
