"My elderly mother is partially blind and disabled. On November 1, 2021 her washing machine broke leaking water in her home. In desperation she called rotor rooter. Roto rooter came out, stopped the leak, and put dryers in and left. They returned a few days later to remove the dryers. The technician quoted my mother a cost of about $3000.00. My mother signed a contract but could not see what she was signing. After Roto rooter Reno removed the dryers they sent a bill to my mother for $9000.00. The contract she signed stated Roto rooter would remove walls, roofing, insulation, baseboard, tile etc. Roto rooter didn’t do any of those things. Roto rooter is price gauging and took advantage of an elderly disabled woman. Roto rooter technicians were in the home no more than 3 hours total. First my mother did not have capacity to enter into a contract as she couldn’t see what she was signing. 2 Roto rooters technicians told her the cost would be about $3000.00. 3 Roto rooter did not do the work in the contract. I believe Roto rooter is commuting elder abuse and fraud."

"Do not hire. They will take advantage of you. We had them out to pump our septic system. They told us our drain field needed a jet-vac treatment (quoted at $3600) and possibly a new pump (quoted at $5000). They filed a report with the county saying that our pump was deficient and we got a letter in the mail saying that we had to take care of it. Those prices seemed really expensive to me so I called around. Multiple other septic companies told me not to hire Septic Solutions as they had often get calls like this from customers questioning prices and if the recommended services are really needed. I had { remove company name} Septic come out for an inspection instead. { remove company name} said that everything was working perfectly and if the jet-vac and pump were needed { remove company name} would charge 5000 total. I had to pay for an extra inspection to get things cleared with the county. Do not hire Septic Solutions. They were not honest and preyed on my lack of septic knowledge. I will be using { remove company name} Septic in the future."

Septic Tanks questions, answered by experts

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.

The most budget-friendly septic system is a plastic tank, which starts at around $2,900. This is $200 less than concrete septic tanks and $500 less than fiberglass.

While you can drain water softener backwash into a septic tank, doing so may cause several problems. One problem is that increased sodium chloride levels from water softener backwash can kill septic tank bacteria, decreasing the effectiveness of this wastewater treatment system. Another issue is that large calcium deposits can eventually stop up the drain field and lead to poor drainage. 

Unfortunately, yes. If your well pump continues working when the flow of water is completely blocked, the motor will burn up. The energy has nowhere to go, thanks to the blockage, so it turns inward. The end result? A ruined well pump and a depleted bank account (once you shop for a replacement.) 

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.
