I did some testing on my well tank system and the results were interesting. Heres some info :
80 ft well, submersible pump, pump control box says 220v, 1/2 hp
Pressure tank blue Structural Fiber w/bladder, 15" diameter x 26" tall. Charged to 38 lbs.
40/60 well pressure switch
4 bdrm, 2.5 bath house. 2 full baths on 2nd floor
And my testing #s :
Pumps fills tank from 38 lb to 58 lb in 11 seconds.
Drawdown on tank from 58->38 lbs is 1.75 gallons
Drawdown on tank from 58->0 lbs is 11.8 gallons
Flow : Basement sink flow (thru filters/softener, 20 ft of 3/4" pipe and 8 ft of 1/2") = 4g in 45seconds
Flow : 2nd floor bathtub flow = 4g in 1:11
As I fully emptied the tank, the water got progressively dirty - red iron 'sand'. I then filled to 20 lbs and flushed many times and the water was cleaner, but still dirty. Water straight from the pump is pretty clean. I guess my tank has quite a bit of iron/sediment buildup. Is it recommended to flush out these tanks periodically?
So... is my system working properly? 1.75g drawdown is not a lot - is the tank damaged or undersized? Since my pump is shortcycling, maybe I should put in a cycle-stop valve?
Any comments are appreciated. Thanks
