"Josh Wilder from Roth Home was excellent. He inspected my outdoor faucet to provide me an estimate to get it fixed. During his inspection he determined there was a blockage and had got the faucet operating with running water in a matter of minutes. He was very professional, punctual, and courteous."

"The actual wok was water mitigation and installation of French drain. Not only did they do a great job installing the drain and putting the yard back together but they found the source of the problem. I had the area dug up twice by other companies who found nothing except ground water, but Aaron and his crew found a broken irrigation pipe. They did the repairs and along with the drain it looks like things are totally solved. Excellent work, very friendly and I truly felt they wanted to resolve tho issue. It was a long day for them but I very happy itâ s fixed!"

Septic Tanks questions, answered by experts

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

There are a few things that can make your drain field fail. These include driving or parking vehicles or heavy machinery on the field, excess sodium in the soil, or having a high water table. You can prevent failure by ensuring your installer checks that your chosen location is suitable for a drain field and properly maintaining your system with the help of a professional.

A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual inspection of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.

A septic system will typically last about 20 to 30 years, although the lifespan can stretch further to 40 years with proper care. Proper septic system care includes having the tank pumped every few years, scheduling cleanings and inspections annually, and conserving water. Also, keep your septic system in good health by only flushing human waste and toilet paper, and never pour fats, grease, oils, or coffee grounds down the drains.

Many septic professionals agree that spring is the best time of year to empty a septic tank. By this point, the temperatures have usually warmed up enough so that the ground is no longer frozen, which makes it easier to access the tank (and less likely for the waste to be frozen inside the tank). Summer and fall are also decent times to do it, but winter isn’t.
