Hello All,
I just want to say thanks to everyone on the forum for some great information posted here.
I purchased a Dayton 4TB19 1-HP Deep well jet pump from Grainger for my 8" dia. well to replaced the bad 3/4-hp. 30-gal bladder tank charged to 28 psi (empty). The only items between the pump and tank are a sediment filter (new) and a water meter (our sewer authority uses this to measure our outflow). 1" copper between the pump and tank as well. New foot valve assembly (also from Grainger) and I matched the jet and venturi to the pump specs.
Water depth is 33-feet and according to the manufacturer I should be getting 9.7-gpm at 50 psi with the current water depth. I did a quick calculation last night by running the water until the pump kicks on and timing how long the pump runs to refill the tank (7.5 mins). Then I measured how much water was drawn until the pump kicked on again (9 gallons) and came up with 1.2 gpm!!!! I also do not suspect that the tank is being refilled all the way. The pump switch is still at the factory pressure settings.
Is this normal? If not, any direction would be greatly appreciated.
Thanks a million in advance.
