"If you want a company that guarantees their work don’t choose Bellows. I paid a ridiculous amount for a new HVAC system and one week after install it stopped working. This happened on a Saturday and they don’t have technicians available for emergencies on weekends and they won’t reimburse for a company that does. They told me not to worry we’ll make it right but the earliest service date they had available was two weeks later. Post sale they don’t care about the customer or about the quality of their work. Make sure to choose another company for your HVAC needs."

Wells and Pumps questions, answered by experts

The precharged pressure tank should start at around 28 psi. The two pressure settings of note are the cut-in and cut-out pressure. The well pump starts when the tank reaches the minimum cut-in pressure. It turns off when the tank reaches the maximum cut-out pressure. The desired water pressure in the household is usually a few psi above the cut-in number. The difference between the cut-in and cut-out pressure settings should be 20 psi. Typical settings for household applications include 20/40, 30/50, and 40/60.

The average life span of a well is about 30 to 50 years. Several factors can affect a well’s lifespan, such as its size, construction quality, water demand, and regular maintenance. Environmental factors, including droughts and earthquakes, can also have an influence. Drilling deeper, getting professional maintenance, and regulating your water usage can help extend your well’s lifespan.

Common problems include low water pressure, no water, and strange noises. Regular maintenance prevents many issues.

When testing the pressure of your well tank, the psi should be two below the cut-on pressure. For example, if your tank is set to 40/60, then your pressure should be at 38 psi.

Another common question is, what pressure should your well tank be set at? The standard rule of thumb is to set your well tank’s pressure at 2 psi below the cut-on point of your pressure switch. So if your well is set up for a high cycle of 40/60 psi, your pressure should be set to 38 psi. If you use a low setting of 30/50 psi, you would set the pressure to 28 psi.
