"Lou and Bryce showed up at the time that was discussed. Lou was very polite and professional. He gave us his professional opinion as to what was happening. Last year, we were told by another company that our leech lines had collapsed. Since replacing the leech lines was not an option due to county regulations , we could have been looking at replacing the entire septic system. If we would have had have a new septic system, it could have costs us between $20K-$30K. Lou said he couldn't be sure but he could surely find out what was going on. He called Aaron, he brought out a back-hoe the same day, dug up the area between our septic tanks and distribution box and discovered it was the line between our tanks and distribution box that was clogged solid. We, also, found out the leech lines were working fine. They pumped both our tanks, dug up and replaced the clogged line, put a riser and lid on the distribution box and refilled the hole. We've lived in our home 3 years and have used 2 other companies when we have had issues. Hopefully, our septic issues have been resolved for a while but if anything new arises, we will be calling Aaron/Andrew's Septic."

"During Freeze-agaddon 2014, Greg was the only one able to guarantee that someone would be out today, and the two guys he sent out were fantastic - easy to work with, very detailed and specific about what they were doing and why, and fixed a major problem thoroughly and quickly. Waking up to a pool of water in the basement due to burst pipes is anything but ideal, but Plumb Tech Services turned a Full On Crisis into a Problem Solved quickly and effectively. They also spent time after the fix going over various ways to prevent it from happening again. Very helpful and informative. If I ever have a plumbing problem of any kind, I will definitely be using them again (though hopefully I won't need to!).

"This would have gone pretty well except that when John (son of Henry) came to look at the job he told me that they would save and replant the bushes and plants that would have be removed to make their initial hole at the curbside city water connection (about 2'x 6' on surface). This was necessary to allow their underground-pipe installer to reach the depth required. When it came to "replacing" the plants, all they did was dig some holes in what was now a clay surface, pick up the plants with what topsoil balls remained around their roots and put them in the holes, doing little else to properly replant them. I have had to get my landscaper out to finish the job. They did do a very nice job of connecting the new copper water line to the house waterline in the basement and cleaned up well. City inspector checked both ends and was satisfied. Bottom line: if this installation had not had to start in our street-side garden, but maybe just in our lawn, I would have been happier with the results."

Septic Tanks FAQs, answered by experts

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.

Depending on local conditions, a deep well may be a better choice than a shallow well. Deeper well depth accesses groundwater that has been naturally filtered through many layers of soil and rock. This reduces surface contaminants and may offer cleaner water, but deep wells cost more money to build and maintain. The water may be harder and have higher radioactivity, too. 

Depending on the size and location of your septic tank repair job, you may want to let the septic pros finish before tackling other backyard work. However, in some cases, it’s not a bad idea to coordinate between your providers if the timing’s right and your septic repair pro says it’s safe to do so. For instance, if the septic repair work is happening in the fall, you might want to take advantage of the opportunity to prepare your backyard landscaping for winter , or in spring, start mulching the garden beds.

While mound septic systems can provide cost-effective wastewater treatment in many instances, they do come at a significant initial installation cost and require a lot of space on your property for the mound and its replacement field. The installation cost is so high because this is a project that requires an exceptional level of skills and expertise to execute properly.
