My well water pressure range is from 40 low side to 65 high side. What can I expect for the amount of water stored in this tank?

The measurement is based on the standard RO systems with the recorded input water pressure.40psi - tank fills 6.1 gallons50psi - tank fills 7.8 gallons60psi - tank fills 9.0 gallons70psi - tank fills 9.7 gallonsActual storage capacity may vary.

What are the exact dimensions of this tank? amazon says 18x18x25 and the manufacture web site says 15 3/8"d x 22 7/8"h. i have a tight fit.

My tank stands 23" high and 15.5" wide. It is sitting on the provided base.

The tank ships with a black rubber plug in the valve fitting, should this be removed?

Hello, no, there is an opening within that diaphragm for the the water to enter and exit. Please leave it in place. If you need any help or assistance, feel free to contact us directly by calling 1-800-880-4808 or e-mailing us at info@apecwater.com. We are in the office from Monday-Friday from 8:00am-5:30pm PST.

This tank will work if i use it with the valve facing up, but will there be any negative affects to the bladder if i use it in this orientation?

Mine has been valve up since I got it, still works great. I'm pretty sure it can't and doesn't make a difference.
