"The "technician/salesman" Eric could not replace a simple furnace motor. He said he couldn't find the motor number, but instead tried to sell me a new furnace. I told him no so he left. I spent a few minutes in the internet and found a motor at Grainger and replaced it myself. Hoffman charged me $95 for what was in reality a sales call."

Septic Tanks questions, answered by experts

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

Septic tanks naturally have bacteria that break down some of the solid waste in the septic tank. However, sludge buildup is just part of owning a septic system. While liquid wastewater can be filtered and treated through the system, a septic tank company has to pump the septic tank out at least every few years.

No, you cannot have a traditional septic tank without a leach field. Without a field, there would be nowhere for the wastewater to go after it leaves your septic tank. If you don’t have enough room for a full-size leach field, you could consider another type of septic system that doesn’t take up as much space, such as a mound or sand filter system.

While abandoning a tank without treating it and following strict rules is illegal, there are several other ways to dispose of an old septic tank. One standard method is to pump out and crush the tank where it rests and bury it in the soil. Another is to remove it and transport it to a landfill. Finally, if abandonment is the best option, your contractor must pump out the tank and fill it with inert material, such as sand or concrete, depending on local regulations.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.
