I recently moved into a house with a well and I was told that the layout won't work right. It has the pump, a chlorinator, a holding tank, the pressure tank and then the dechlorinator. I was told that the pressure tank needs to be between the pump and the holding tank for everything to work properly. I guess the former owner used the system for years so is this true?

I would appreciate any information that can clarify if the layout is correct or not and if it isn't what problem does that create?

Thank you!

My personal preference would be to have the pressure tank holding unchlorinated water only because chlorine adversely affects rubber. A lot of the houses on well systems around here have a pressure switch, T for house water, and the pressure tank across the T. It sounds like your setup would work fine, but you will most likely experience more pressure tank failures than if the pressure tank was before the chlorinator.
