low pressure in house

[petfixer]

All faucets between the pump and the bladder tank/Water softener are normal. All faucets in the house have normal pressure for about 10 seconds then peters off to a trickle, The 30/50 switch is less than a year old, pressure in bladder tank is at 28 psi and I replaced the pump motor 2 days ago. thank you for any help.

I figured out the problem. I had replaced the outside filter with a (expensive) carbon filter and it was restricting the water flow. I replaced it with a pleated filter and the pressure in the house is back to normal.
