"Marcus came over the day after I requested the quotes (quotes requested Sunday, he came Monday.) He assessed the situation and explained options and pricing. He very willingly attempted the lower cost option first, even though we had doubts it would work. He told if it did not work and we had to go to the higher cost option, I would only be charged for that, not both. We did have to go to that option and he was able to clear the clog from my sewer line. He then inspected with a camera and showed me that there were several roots intruding on the line. He recommended repeating the process with a nozzle designed to remove these. He did not have that on his truck, so another visit was scheduled for today with a different tech. This was also successful and it was clear from the camera inspection at the end that the roots were gone. I was expected a horrible mess from this process, and was very happy that both operations were completed with minimal additional sludge in my basement."

Septic Tanks questions, answered by experts

There are no major drawbacks or risks to oversizing a well pressure tank for your well. In some cases, having a larger pressure tank can increase its lifespan as it won’t have to cycle on and off as often, resulting in less wear and tear. Keep in mind that larger pressure tanks have a higher upfront cost and take up more space.

The lifespan of your well casing depends mainly on the material it’s made from. Stainless steel and galvanized steel casings are designed to withstand the pressures and environment of deep-water wells but are susceptible to corrosion. Most steel casings last from 20 to 35 years, on average. PVC casing is highly durable and, if used correctly, can last up to 50 years.

Anaerobic septic tanks are the most cost-effective type of septic system, with an average cost of $3,000 to $8,000. Sand filter septic systems are the next most affordable, ranging from $7,000 to $18,000. Mound systems have the highest price tags of the bunch, coming in at $10,000 to $20,000 per installation.

There should be a red button or an on/off switch on or in your box. Press the button or flip the switch, then turn it back on by doing the same action again. If this doesn’t work, reset the breakers inside the box by flipping them off and back on again. After this, your alarm should stay off if there’s nothing wrong with your system. However, if the alarm is still sounding and there’s still a red light on, it’s time to call a pro for a diagnosis.

If you notice a septic smell in the house, you can either call a septic system repair company or a plumber. These professionals have the proper licenses and equipment to investigate the pipes and septic tank while keeping your family safe from sewage gas exposure and raw sewage leaks. They will be able to find the problem as soon as possible and get it fixed so that your home can get back to smelling fresh again.
