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."

"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!"

Septic Tanks questions, answered by experts

Good news: You’ll naturally increase the bacteria in your septic tank simply by using it. If you want to encourage more good bacteria growth, stop using products and household cleaners that kill bacteria, such as bleach and harsh chemicals. Never flush antibiotics, and make sure only water and waste go down the tube—not paper products, feminine hygiene products, or diapers.

Normally, when your well pump turns on or off, you’ll hear a small click. This isn’t anything to worry about, but it can be a problem if it’s clicking continuously. This can indicate that the well pump is short cycling—the pump continuously turns on and off.

This can wear out the motor and provide uneven water flow. If this happens, you may need to get it looked at by a well pump professional to see if you need to repair the switch or pump.

Most home wells start at 100 feet, and many go as deep as 200 or 300 feet. 

It takes quite a lot of water to meet the demands of showers, toilets, faucets, and appliances like dishwashers and laundry machines, and shallow wells struggle to provide this amount quickly. If you anticipate having high water usage in the future, it’s often better to drill slightly deeper and give yourself a bit more water storage than you need.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain.
