"Couldn't be happier with the service we've been receiving from Great Bear Septic over the years. They are professional, take the time to answer our questions, and are unfailingly cheerful. They are a pleasure to work with. When we first purchased our home ten years ago, we had Earthcare take a look at our system. They tried to talk us into a $20,000+ replacement of our system. Something didn't seem quite right, so on the recommendation of friends, we reached out to Great Bear. Ten years later, with regular pumping from Great Bear, system still works great. In addition to all their other fine qualities, the team at Great Bear is trustworthy! Could not ask for more."

"As a real estate owner/broker and homeowner. Billy does all of our septic inspections and necessary repairs for my real estate agency and its clients. His thoroughness and attention to detail are outstanding. I am confident when I recommend him to my clients. He has even performed his services on my property, installing a septic tank and fields. The septic tank was under a manicured landscaped area with pavers, stone walls, and steps between my house and garage, with very limited access. He actually built a ramp for the machines to traverse the stone wall to access the site. Removed the old septic tank, installed the new one, and put everything (including plants he had to remove) back in the same place. I can't believe it looked like it never happened. I recommend Billy to everyone I encounter who needs septic or drainage work."

Septic Tanks FAQs, answered by experts

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.

When a septic tank is full, it needs to be professionally pumped. The average cost of a one-time septic tank pump is about $400, or $0.30 per gallon. If your septic tank is full, you may notice that you have issues flushing your toilet, pipes are draining very slowly, or you have a sewage smell lingering in your home or yard.

Bladder and diaphragm well pressure tanks are usually pre-charged at the factory. Even so, it’s important to check the air pressure in the tank using a tire pressure gauge on the relief valve. The instruction manual usually calls for 28 psi. Use a hand pump to add more air or release some air from the tank to reach the desired number. Check the pressure periodically to see if you need to add more air to the tank.

Yes, you can adjust your well pump pressure relatively easily by yourself. You’ll need to remove the cover from your pressure switch and adjust a nut that controls cut-in pressure. Learn more about how to adjust a well pump pressure switch with a step-by-step guide to setting your water pressure.

Common signs that a septic tank is full include plumbing issues, odors, and changes in your yard. You may notice wastewater or sewage backing up into your home's drains, or that sinks, tubs, and toilets are draining slowly. Gurgling or bubbling sounds from the pipes are also a key indicator. Outside, you might smell foul sewage odors around your house or the septic tank area. Look for pooling water, spongy soil, or a marshy environment around the drain field. Another tell-tale sign is a patch of grass over the septic system that is suddenly lusher and greener than the rest of your lawn. If you notice any of these signs, you should contact a septic professional for an inspection and pumping.
