"We are currently in an exception heat spell and I am running my water well supplied lawn irrigation system daily. This morning, I notice my sprinklers had not run. I checked the breaker and that was fine. I called the Ballard office and to my surprise, they said they would have someone there that afternoon. My pump is ~10 yrs old, so I was not expecting a pleasant outcome. Blane Greenhaw and an assistant showed up and within thirty minutes had my pump running at the minimum service charge. Very pleasant and professional crew. -- Great job."

We are licensed and don't have to come back we cover the Livingston and surrounding areas 4 years of experience do it right the first time

"Shaun and his crew did a great job. Our property was completely flooded, and was very difficult for the guys to work here. We literally had a huge mud hole in the back of the house, that caused them all kinds of issues and problems. But they did a great professional job, regardless of everything . They overlooked the conditions and saw the greater need. I would recommend Shaun and his crew to anyone needing a new septic system."

CP has been providing quality home warranty products since 1998.

"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."

Septic Tanks questions, answered by experts

Septic tanks are typically buried between four inches and four feet deep, depending on the property, the soil, and the size of the tank. When the septic tank is buried on the deeper end of this range, it may be harder for you to locate it on your own with a soil probe or just by observing the yard for signs of the tank. However, if you have trouble finding the septic tank, a pro will be happy to help you.

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

According to the Environmental Protection Agency (EPA), septic tanks must be located a decent distance from places subject to flooding or surface ponding. Additionally, septic tanks should be installed on level ground so that the waste can properly settle in the tank. Most tanks are located 10 to 20 feet away from the home. More specific requirements vary by location, so call a local septic pro or your local health department for more information.

Unlike an urban sewer system that runs wastewater into a central drainage system, septic tanks are a house-by-house system. They are the ultimate destination for all your house’s wastewater—from bathtubs, showers, sinks, toilets, and washing machines. Wastewater flows into a tank buried in the ground outside your home, and then water runs from the tank to a drainage field using sloped pipes.

Septic tank costs vary with the size of the tank—and the size you need depends on the size of your household. For example, a 1,000-gallon septic tank is the minimum size for most 1-, 2-, or 3-bedroom homes, and costs between $900 and $1,500. However, the tank is only one part of the septic system—which costs significantly more to install. If you’re setting up a new septic system (rather than replacing an existing tank), you can expect to pay about $7,310 on average. Costs can be higher depending on the type of septic system you choose.
