"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

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.

Common signs that a septic tank is full include plumbing issues, odors, and changes in your yard. You may notice wastewater or sewage backing up into your home's drains, or that sinks, tubs, and toilets are draining slowly. Gurgling or bubbling sounds from the pipes are also a key indicator. Outside, you might smell foul sewage odors around your house or the septic tank area. Look for pooling water, spongy soil, or a marshy environment around the drain field. Another tell-tale sign is a patch of grass over the septic system that is suddenly lusher and greener than the rest of your lawn. If you notice any of these signs, you should contact a septic professional for an inspection and pumping.

Most homeowners know there’s a septic system problem when they can smell one. However, this isn’t exactly a scientific deduction method. Consider some of the other signs: standing water or constantly damp earth in the drainage area, toilets and sinks that won’t drain or frequently back up, and loud plumbing. You really need to be on top of routine maintenance with septic systems in order to avoid such unpleasant symptoms of a septic issue. 

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product.
