Have a plumber check the pressure and volume at your main.

Jhasey How do you know its always running??? just curious we cant hear ours.... which I dislike, sort of, cause the old 110- 230 volt one, in the small pump house .I knew it was working. only aggravating ,cause the old owners(deceased) only had a small 6 gallon pressure tank... Jean

The toilet and sink are separate issues- the toilet likely operates by gravity. The only thing water pressure affects is the time it takes to fill the tank. Check out your toilet's rating at the CUWCC site- if it's bad, well, it's a bad model. One other thing to look at with the sink is whether the screen at the aerator is clogged. Unscrew that and take a look. And make sure that the cutoff valves are all the way open.

With a deep well system, your water pressure is governed by the pressure tank. The pump is turned on and shut off by the pressure switch located on the manifold connected to the tank. Turn the pump off, drain the water from the tank by turning on a faucet at the lowest point in the house until water no longer comes out. Take a tire pressure guage and check the air pressure in the tank. If the pressure switch is rated at 20/40, the air pressure should be 18psi There should be a label on the tank with pressure information. The tank supplies water pressure to the house, when the pressure in the tank reaches 20psi, the pump comes on. The pump will pump water into the tank until it reaches 40 psi and then the pressure switch will disengage the pump. Sometimes a tank becomes "waterlogged" and pressure begins to drop. A good indicator of this is when the pump comes on almost immediatly when the water is used and then cycles on and off quickly. Other tanks use a bladder where either the air or the water enters and air pressure increases as the water enters the tank. The bladder then supplies pressureized water into the plumbing between the 20 and 40 pounds mentioned above. Sometimes a bladder will develop a hole or crack and become waterlogged. In some case, the tank will have to be rplaced. Other tanks allow you to replace the bladder. Be certain you understand that if you desire to increase water pressure, your tank and pressure relief valve must be rated for the increased pressure. Also know that your faucets and other fixtures are tested at a pressure of 60psi. As you near that pressure, the fixtures will tend to drip as they get older. A pressure of 20/40 should handle just about any household. Some of the newer washing machines require a pressure of at least 20psi to fill or, they will go into a default mode and shut down. There's more to know should the above not apply to you or if you have questions you think I may be able to help with, feel free to contact me via email.
