Well, I'm a witness to it. We specifically talked about it when the job was finished. I think the tech was equally surprised.
First..he doesn't have to ring the doorbell. Goes right to the spa and turns off power. Doesn't need to talk to customer to do the job. Customer doesn't need to be home.
Four screws to remove panel.
Remove and replace circ pump...squeeze lines, two screws to hold pump in place, attach electric line.
Start spa, check operation, replace panel, put his tools away (not much needed)....six minutes.
Talk to customer (me). I sign paperwork. Off to next location.
Add a couple of minutes. Service order says ten minutes but job itself was complete in six.
