Question about Utilitech 20-Gallon Vertical Pressure Tank LPT-20
If there is only 1 pipe on tank how does water exit
So, a pressure tank is used as a back up system for when the water pump is on the off cycle; why does the pump have an off cycle? Is it just to give the pump a break so it does not wear out? However it all works, I'm glad that there are systems to provide water pressure for our sinks and showers! http://www.bwsfabrication.com

Pressure tanks do just that in a water system. They create pressure for water to flow when the water pump is on the off cycle. A manifold is plumbed into the tank from the main line coming from the well. The main water line continues to the house plumbing from the manifold. So it's line from pump to manifold - to tank, and from manifold to main into house. The manifold also has tappings for the pressure gauge and the pressure switch. The pressure tank creates water pressure. The water does not flow through the tank. Pressure tanks also have to be 'tuned' or adjusted to the low end pressure set by the pressure switch. Actually the tank pressure needs to be set 2psi below the low end pressure. Most residential water systems are set to operate between 20 -40, or 30-50 psi, which is set by the pressure switch, which in turn , turns the water pump on and off. So if a system operates between 20 and 40 psi, the pre-charged pressure of the tank should be 18 psi. Pre-charged means the tank is drained of water with the water pump OFF. The tank pressure is then checked adjusted by way of the air valve on top of the tank ( A tire gauge works). Pressure tank mainfolds are a common plumbing part.
