Hello everyone... found this site with the hopes that someone can help me out.

I am on individual well system, I recently replaced my water softener with a new one and added an iron filter. Since the replacement, the water pressure in my house has decreased especially on the second floor. If more than one faucet is running, the pressure goes to a dribble upstairs. I checked the valves and they are all open. I do have a pressure tank. If I missed any other vital information, please let me know.

Thanks!

I don't know the answer - post this in the plumbing section, you'll get a more quick answer.
