Saturday days ago we had a problem with our water delivery via a well. In the end the fix was to install a new pressure tank and add an additional check valve a the pump. The well was run until the water was clean and then everything was hooked back up. I turned on the outside hose and got and got some nice dirty water for a couple of minutes paid the well guy and went back inside.

Afterwards it was observed the water flow rate in the house was awful. I checked all the areators and had to replace one. We are in Florida and on the odd occasion when we have had to mess with the well, etc we always have sand that pops up for a few seconds before the water runs clean, after that no problem.

The pressure tank is set to 38psi and the pressure switch is 40/60 though I have no way of verifying it's actually set right. The outside hoses run fine (so I'm ruling out the pressure switch for now) with good flow and velocity but the inside is barely running. I put the water softener and iron filter on bypass with no change. So the question is how do I diagnose the source of the problem and resolve it? Is there any way to determine IF and WHERE a clog exists in the supply lines?

I realize this is a very open ended question and I probably haven't even come close to answering all the questions but without knowing what needs answered it's tough to state it up front.
 
When your pump tank and all went bad, were you seeing a lot of sediment?
 
No, the check valve on the pump was jammed open so while the pump was out and extra one was inserted in line. I ended up talking with an old friend (1000 miles away) who is a master plumber. I went to each sink and popped the supply line off at the faucet and ran each one until they were clean. A couple of aerators need to cleaned up wile others were fine.

I have to say I'm really amazed how little sediment it takes to really restrict water flow rates inside. I still don't understand the cascading effect turning on more than one source took. Maybe I'l read up on pressure, flow rate and velocity so I can get a better understanding behind how it all works together.

So I'm back up and running. I still think plumbing is a voodoo science sometimes too.
