I need to buy a water pressure tank for residential use but don't know which brand to buy.

Brands tend to be specific to region... and this is an international Site. You could start by telling us what country you are located.

Are we talking galvanized water tank or a bladder tank? Back to you, Tom

Do you have one already? Call a few locals and see if they can replace it, or what they are offering. Once you know what they sell, and service, you can make a reasonable decision.

Give us a zipcode, and we can steer you to a REPUTABLE dealer, that can guide you through the process of choosing.
