Hi,
I am running to a problem with a pump and am working with the original installer to get it resolved but have concerns and am looking for any insight which can be provided.
In 2005, the well was put in. Here is the info on the well:
375 Total Feet
Pump set at 250 feet
Water Level at 150 feet
Casing down to 140 Feet
Approximately 30 feet from the well to inlet in house.
Original pump was a Franklin Jacuzzi SandHandler 18gpm with a 1.5hp motor tied to a Constant pressure SubDrive 75.
The house has a 4 ton geothermal (open loop) unit which can pull between 8 and 10 gpm, otherwise typical household water usage. The PSI is set to 50psi constant pressure.
After 13 years the motor and pump have died.
The driller has put in a 10gpm Franklin tri-seal 4400 with a 1.5hp motor and says it is sufficient to run the geothermal and normal household usage. I have concerns that it is not and it may need a larger pump.
The driller calculates a the feet of head just shy of 400ft (385ish). Is this the feet of head referred to on the performance curves from the manufactures? If so, then the 18gpm pump was only putting out 10ish gpm according to the spec sheet I got. The driller says the 20gpm pump doesnt have the performance to hit that head figure and I would need to bump up the subdrive75 to the subdrive100 in addition to the pump raising the bill quite substantially.
Given the track record of the constant pressure pumps, it seems like mine is on borrowed time to begin with.
