I have a welltrol wx-202. The pump was continually running never stopping or starting. Thanks to your site I was able to check the pressure in the tank and found 0 psi. I added air per directions. The tank seems to be holding the pressure. Now, pressure builds to cut-off (takes about a minute or 2). At cut-off it drops rapidly (about 20 seconds) to cut-in. So, it seems to me that the pump is running way to much. Per my electricity bill. Do I need to replace the tank.

Sounds more like you have a leak somewhere. If you have a main shutoff valve after the tank; close it and see if the pressure holds. If it does the leak is in the plumbing. If the pump still continues to cycle, the leak is back towards or in the well.

Depending on the type of well and pump, there will be a checkvalve somewhere. It could be part of the pump, or could be somewhere else. If that checkvalve isn't working properly, the pressure you've built up would just push that water back into the well. It could also be a hole in the pipe from the well, and the checkvalve could be fine. If you had a leak in the house that allowed the tank to discharge its accumulated stored water in a few seconds, you'd notice it as it would be gallons, not a drip here or there.

If the leak were underground or under a slab foundation, it may not show up until serious damage is done. Such as underground 4-5' at a pitless adapter outlet connection with a non grouted rock bore well; serious underground erosion can result.

I have changed the nasty little plastic check valve with a new brass one. Pressure is holding steady!!! Now I wonder why it takes so long for the pressure to build back up to 50psi after cut out. (5-10min) Once it cuts out it holds pressure beautifully.

You never said what kind of pump you have. Is it a jet, submersible or other?
Plastic check valves are always a bad choice for water systems.

The tank has nothing to do with your problem. If your sub takes that long to put 5 gallons in your tank, you have a bad restriction somewhere. You don't have any filters in line do you?
I believe by putting this checkvalve in line, you have masked the real problem. The water is still leaking while the pump is running. Once the pressure gets to 50 and the pump shuts off, the check valve keeps the water in the tank. But you still have a leak.
Get rid of the new check valve and find out where this leak is and fix it.

Before I replaced the bad plastic check valve the pressure would build up quickly to 50 psi, shut off and drop quickly. Now it takes forever to build the same pressure, but doesn't drop when the pump stops. How does changing the check valve effect how fast it builds pressure?

You may have had a waterlogged tank and you have since drained it - or you might done something we aren't aware of.
The check valve really shouldn't be there. If you remove it and find that the water runs back down the well again, that tells you what the problem is. Now you have to figure out where it is and repair it.

If I remove the check valve what prevents the water from draining back down into the well? Is there a foot valve at the bottom of the sub pump? I am going to try removing that check valve and see what happens. I have also rigged a pressure gauge to put on the pipe coming into the house before the tank and anything else to test the pressure coming in. What should that pressure range be? I don't know the size of my sub pump.

You have a leak on the well side of the check valve. That's probably why you have that check valve there, installing it makes it look as if the problem was solved but now the leak is serious. The leak can be underground from the well but probably is in the drop pipe. If you have PE pipe for the drop pipe, you run the risk of the pump falling off and down the well.
All submersible pumps have a check valve in or on the outlet of the pump. There should not be another one in the system. That check valve might be your leak.
You don't need to add a pressure gauge to check for a leak, if you start pulling the pump and the pipe is empty, you prove there's a leak; but trust us, you have a leak.
