Okay, so this may seem like a stupid question. However, having grown up in a home with well water I'm accustom to having the traditional tank in the basement. We purchased our new home recently and have been having pressure problems. I went to look for the tank with the PRV to see what our pressure was. All I was able to find was the PRV where the main comes into the house. Is it possible there is some type of submersible holding tank or jet pump of some kind that is located at the well head? Any ideas on this would be welcome. Thanks.

I don't understand. Pump systems do not have PRV valves. Did you mean pressure gage? You should have a bladder tank next to the pump or if it's a submersible it should be on the discharge line after it comes out of the ground. What type of system do you have? Regards, Tom

Thanks for the response. I don't know what type of system I have. I know there is no type of tank in our home at all. There is a pressure gauge where the main comes into the house with a square d pumptrol on it. I guess that's my real question. Are there systems that do not use a tank of any kind?

Never heard of a tankless well system but I guess there could be. Do you have a full basement or is there a section of your home that has a crawl space. Do you have any out buildings, any dog houses that you don't have a dog for, any roofs that sit down on the ground?

There is such a thing as a pressure tank that is in the well casing for a submersible pump.

I think Jlisenbe nailed it if you have a submersible pump.

Title:Water pressure system with pressure tank installed within well casing of well Document Type and Number:United States Patent 6910532
Abstract:A water pressure system includes a pressure tank installed underground within the well casing of a well. The water pressure system includes a submersible pump connected to the inlet of the pressure tank by a drop pipe. The outlet of the pressure tank is connected to a second drop pipe and in turn to a discharge pipe for distribution of pressurized water to a house or other building. A pressure switch is connected to the pressure tank for controlling the submersible pump. The pressure tank includes an outer sidewall with an inlet end and an outlet end. A flexible diaphragm bladder located within the outer sidewall is connected between the inlet and outlet of the tank. In a first embodiment, a tube extends through the center of the bladder between an inlet opening and an outlet opening. The tube has a plurality of holes therein to allow water to flow into and out of the flexible bladder. Pressurized air fills the space between the bladder and the outer sidewall to pressurize the water in the bladder. The pressure tank may be used in combination with a flow control valve, a relief valve, a flow control valve incorporating a relief valve, a standard submersible pump, and/or a variable speed submersible pump to provide and maintain a constant flow of water at a constant pressure through the system.
And that's where your pressure tank lives. Regards, Tom
