"We couldn't be happier with the work they did for us! He completed our septic system, leach field, and slab preparation, but went above and beyond what we expected. Our property was very rough, full of rocks, stumps, brush, and bushes. He took the time to remove stumps and rocks, used the excavator (very skilled) to smooth out the entire property, built a beautiful rock wall using rocks dug from the property, and seeded and hayed the area. The transformation is incredible! Everything looks so nice, and we couldn't be more pleased with how our property turned out. It's not often you find someone who takes so much pride in their work and goes the extra mile to make sure everything looks great. We highly recommend him and would absolutely hire him again."

"great, Derick was very communicative, kept me informed all through the project and gave me cost estimates as the project grew in scope. I needed semi-emergency work on my septic system and responded right away and fixed the problem."

"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."

"The gas company came in to replace a meter.  They found that the vinyl siding company we used in the past had cut and covered the safety valve.  The one night that it's super cold out, the gas company had to shut off our gas (heat)!! I called Richard at 9:00pm.  He got back to me first thing in the morning and had his crew take care of it by 7:30am.  They are really THE BEST!!  The gas company is here now and hopefully we'll have heat soon."

Septic Tanks FAQs, answered by experts

Yes, a bigger well pump can increase water pressure—up to a point. If you currently have a well pump of 8 GPM, you might notice a pressure boost when you go up to 10 GPM. However, overshooting significantly (going up to 15 GPM for an 8 GPM home) can strain your well system and result in things like burst pipes that can decrease your water pressure and make for costly repairs.

Your septic tank naturally contains the beneficial bacteria it needs to function, so you typically don't need to add more. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three overripe tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many experts consider them unnecessary and potentially harmful. The most effective way to maintain a healthy bacteria population is to avoid using chemical drain cleaners, which can kill the good bacteria in your system.

Soda, coffee, and other soft drinks are highly acidic. This affects the pH in septic tanks, causing them to require more frequent pumping. However, a vast majority of people don't need to worry about septic system disruption. Pouring out the occasional flat soda doesn’t affect septic systems to the same degree as the high-volume dumping from restaurants and convenience stores.

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.

An outdoor water valve typically has a round or oval handle that you can turn to control the water flow. It may be located in a protective box or pit near the property line, where the main water line connects to your house.
