Okay... Here is some of what you asked for...
Pipe size is 2". Sand filter. Everything is in good working condition.
There are no other features. It's a pretty plain set up. One suction port and one discharge.
I have been running the pump 8 hours per day. I'm basing this off of a book I purchased on pool maintenance. There were no calculations in the book, it just said that running the pump for 8 hours a day is a good rule of thumb.
The only control system I have is a mechanical timer. I have it running from 10:00 am to 6:00 pm. I am up against the mountains in salt lake city, so we don't get direct sunlight until the sun peeks over the ridge around 8:30 am in the summer.
I'm looking for my electric bill to give you a rate, but I should mention that the $350 electric bill was not only for the pool. It is for the whole house. I pay about $100-150 a month without the pool.
Some other things that you didn't ask for that might help...
The pump is a jacuzzi magnum force pump. Production date: July 1999.
The pump body (not the motor) says model: 2umf-s order number: 94027120
The motor says... Magnetek part number: 10-184950-22.

Hope this helps... Thanks again for the advice!
