"Aurelio repaired a very difficult underground leak in our water main in front of our house, and he did it within hours of being contacted, by using time between jobs for excellent communications in advance, and then working very efficiently, knowing precisely what needed to be done. He was also able to charge a very reasonable cost by pinpointing the precise repair needed, with no attempt to upcharge or sell us on unnecessary upgrades, completely unlike what I have seen other larger companies try to do when we asked for quotes or services. In short, his integrity is as impressive as his skill and knowledge, which are both very great. He then concluded the repair with an immediate and highly detailed invoice that he completed and emailed to me within less than 3 minutes. I was truly surprised at how easy and reliable he made everything work for us, and he was worth every penny."

"The person performing the service had to make several trips because one of the "new" parts turned out to be faulty. I found both Complete Protection and their local repair contractor to be both very responsive and totally professional at every stage of the repair process."

"Kevin came out same day to clear an obstruction in lateral sewer line. He did more work than I even requested and was so grateful he could also fix a broken toilet seal; evaluated a broken tankless water heater and took picture of my collapsing sewer drain. He explained everything so clearly and patiently, it was really a pleasant experience even finally finding out what repairs are needed with a written fair estimate. Prices are very reasonable. John Gleeson will always be my “go to” plumber."

Septic Tanks questions, answered by experts

Beyond the type of well pump, there are a few other factors to consider when selecting a well pump. Keep in mind the depth of your well, your average water usage, and the PSI of your water-consuming appliances to determine the appropriate motor horsepower and size of your well pump.

Yes! Toilet paper can be flushed if you use a septic tank. While unique toilet papers designed to be used with septic tanks are available, many people have no problem flushing regular toilet paper with a septic tank, so long as you don’t flush too much toilet paper all at once. Do not flush any type of baby wipes or bathroom wipes, even if they say “flushable.”

Good news: You’ll naturally increase the bacteria in your septic tank simply by using it. If you want to encourage more good bacteria growth, stop using products and household cleaners that kill bacteria, such as bleach and harsh chemicals. Never flush antibiotics, and make sure only water and waste go down the tube—not paper products, feminine hygiene products, or diapers.

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. 

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.
