"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

Septic Tanks questions, answered by experts

To determine the right size for your submersible well pump, find your well depth, water demand, and well casing diameter. The pump should match your well's specifications and meet or exceed your drawdown and pressure requirements. 

For precise sizing, make sure to research the different well pump sizes, consult the manufacturer's recommendations, or seek guidance from a professional well pump installer.

A septic smell may be harmful because sewer gas is dangerous depending on the exposure amount and length of time. Sewer gas is made up of multiple gases, including hydrogen sulfide, methane, ammonia, and carbon dioxide. Some of these gases, like hydrogen sulfide and ammonia, are toxic to humans and can be fatal in high concentrations or long exposures.

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more. 

A septic system inspection costs $100 to $200. Doing so can spot issues early so you can plan for necessary repairs ahead of time and save yourself the issue of a backed-up septic tank. Some septic tank repair professionals do an inspection as part of their yearly maintenance on your septic tank if you choose to pay for that service, but you should shoot to have a septic system inspection completed at least once every two to five years.

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.
