Ok, Here is my problem. I have been in this house for 2 years ( my first house with a well) without any problems, now when I run a fixture or fixtures I will lose pressure for a couple of seconds then pressure is fine.
I do not know what size or type pump I have
The bladder is a wellxtrol model 205
Here are the pressure readings

at start of test:
tank=42 psi gauge 50psi

open fixtures pressure drops to cut-in
tank=32psi aprox. gauge 30psi

at soon as switch closes at 30psi cut-in
pressure gauge drops to almost 10psi lose water than few seconds later pressure comes up.
will take 30-40seconds to reach cut-out of 50psi whenthe fixtures are still open.

any help would be greatful. what should I check next.
