"When our septic pump stopped working I called Superior Septic. Angel came out and figured out the complicated problem that could have eluded someone with less experience, and skill. I am impressed with how fast he fixed our pump. I highly recommend him and his company."

"They are family owned and operated. Jorge was very friendly and professional, and did everything to help. They even moved the tops of the tanks that must have been over a hundred pounds to a different location and installed Risers. We had to find where the septic tanks were, and what type of tanks, and what was needed to bring the tanks up to code. So we can sell the property. We would recommend them to anyone."

"Ybarra Professional Builders did 2 big plumbing projects on my house and property. Not only did they install a brand-new main water line to replace the old leaking galvanized steel pipe, but they also re-piped my house's plumbing as it was also made from that same rusting out galvanized steel. I also had some other major work done by them at the same time (tree removal and sprinkler repair) but since Home Advisor asked for a specific type of project for this review, I will only review the plumbing projects. Vlad was the project manager for all of these projects. He coordinated all of the sub-contractors' work and got the projects done in a timely manner. There were none of the time issues that I had heard about with other contractors, such as waiting weeks between one phase of a project to get the next one started-after one phase was done, the next phase would begin with no more than a day or two in between. He was very pleasant and very patient with my many questions and concerns and kept me up-to-date with what was happening. The project that I most dreaded, the house plumbing re-piping, was not as bad as I thought it would be, to my great relief. All of the people who I dealt with at Ybarra were pleasant and professional, from the sub-contractors to the office staff. I think the quality of the work performed was very good. In the additional clean-up phase, the holes in the drywall where the plumbing had been re-piped were patched and painted, and the concrete where the driveway had to be cut to replace the main water line was re-poured. This portion of the project was available as an additional cost, but the workmanship was very good. I had heard and read many horror stories about dealing with contractors so working with this group was a pleasant surprise. Thank you, Vlad."

"I had a problem at my vacation rental. John contacted me quickly when I posted my problem for quotes online. I had a failing septic. It was no longer draining. John came out and accessed the the situation and based on faulty drawings I supplied, he gave me an estimate for repair. I agreed to the figure. When he discovered that the drawings were wrong and he only had to dig up 5 feet (not 14) between the septic tank and the seep box he lowered his estimate. You can't ask for more honesty and fairness. He and his worker completed the job in less than 2 days. Hire him!"

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks questions, answered by experts

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.

Septic systems typically require servicing every 3-5 years, but frequency varies according to household size and tank capacity.

To keep roots from growing into a septic tank. However, there are other steps you can take if existing tree roots are getting close to your septic tank. For one, you can install root barriers, which physically block roots from reaching your septic tank. You can also use chemical solutions in your yard or plumbing system to deter root growth.

Neither system is necessarily better or worse than the other, but one of the two might be better for your needs. For example, anaerobic systems are less expensive than aerobic ones and don’t use power to run. On the other hand, aerobic septic systems don’t take up as much space and are typically more efficient than their anaerobic counterparts.

The costs depend on whether you are buying into an existing well or starting from scratch. The average well drilling cost is between $25 and $60 per foot. The average cost to repair a well is between $350 and $1500. If you have a shared agreement and a community association, there will be additional legal and administrative fees.
