I have a well pump system with 2 diaphram pressure tanks in series. They are working good and have good pressure. My question is can I tie in my cold water line going to the shower and sink and stuff in between the pressure tanks. I had it tied in right before the water heater and I think that was causing my problems with pressure.

I have a well pump system with 2 diaphram pressure tanks in series. Please explain. Are the tanks hooked one after the other on the same line? What's the advantage in having two tanks?
I think that was causing my problems with pressure. I didn't know you had a pressure problem until the last sentence. Whatever happened to
Please explain.

Good question. Can't imagine why tieing in before the WH would cause pressure problems.
