Customers say: Quality work

"I would give Austyn 100 stars if I could. He made the project go smoothly. His personality, level headedness, his problem solving skills, knowledge of his craft and the ability to work with others so appreciated. While excavating for the septic Leitchfield, I had him do other work on the property, moving earth and building a retaining wall. When he discovered a huge cavern where earth had eroded to the point of danger, he immediately ordered everything and had it fixed in a few days. He was here on time, and he stayed on the job until it was finished. Here ever day. That isn't always the case, especially when unexpected things (like a cavern) show up and the job takes longer than planned. Everything turned out perfectly, we passed the city inspections on the first try. You can't go wrong with Austyn, he is someone you can trust."

Throughout the installation, they worked diligently, respecting my space and ensuring everything was installed correctly. Their clear communication and transparent pricing made the experience stress-free. Now, my home is consistently cool and comfortable, and I couldn't be happier with the results."

"It was great luck that Jason of J Drains was working on a job near my home and was able to come by after he finished that job to check my hot water heater. He fixed it right away because he spotted what was wrong quickly. Jason was very professional and polite. I recommend this company!"

"We live in Carmel Valley and hired Justin and his team to do an addition and full remodel of our home including re-plumbing, rewiring, redoing the septic systems and replacing our ridge line beam, after having a terrible experience with our first contractor. Justin's team picked up the project while in the permitting phase and did a fantastic job on all aspects of the project, from pulling the permits through the final. They were always available, transparent with their bid process and exceedingly fair when unknowns came up in the project. Doing a high-end remodel is never cheap, but their pricing was fair, transparent and they worked with us to fit everything we wanted into our budget and schedule. Could not recommend them more highly!"

Septic Tanks FAQs, answered by experts

Septic drain fields should be at least 10 feet from the property line, though exact requirements vary by location. Some areas may require further distances, such as 25 feet or more, depending on soil conditions and local health regulations. This extension ensures proper wastewater absorption and prevents contamination of neighboring homes.

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.

Options include submersible, jet, and centrifugal pumps. Choose based on water needs and well depth.

A septic alarm can sound different depending on your system, but often, it’s a loud, repetitive beeping noise or a steady, high-pitched noise. It may also be a loud buzzing noise. To confirm the noise is your septic alarm, check your alarm box for a red light. You can also silence your alarm with a red button or switch on the box. Look for something that says “Test” or “Mute.”

Yes, it is generally okay to oversize a well pressure tank, and it will not harm your well system. The primary advantage is that a larger tank reduces frequent pump cycling, leading to longer, slower cycles with fewer startups. This can result in less wear and tear, potentially increasing the lifespan of the pump and conserving energy. However, there are drawbacks to consider. Oversized tanks have a higher upfront cost and require more physical space. While not necessarily a bad thing, opting for a tank that is appropriately sized for your well is often the most efficient choice in terms of cost and space.
