"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

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

Common signs that your well pump is failing include fluctuating or consistently poor water pressure, sputtering water from faucets, or a complete loss of water. Other indicators are unusual noises coming from the pump, the pump running continuously, dirty or cloudy water, or a sudden, unexplained spike in your utility bills. While some issues, especially after a power outage, might be resolved by simply restarting the power or priming the pump, persistent problems suggest a more serious issue. If you notice any of these red flags, it is recommended to call a professional well pump service to inspect the system and determine whether it needs to be repaired or replaced.

Start by finding the septic tank, marked by an access lid near your home. From there, the drain field extends outward in a series of trenches. Look for greener, lusher grass, as drain fields promote plant growth due to moisture and fertilizer. You can also check property records, use a soil probe to detect damp soil, or hire a septic professional with ground-penetrating radar equipment to map the drain field’s location.

Your drain field or leach field should be 1 to 3 feet under the ground. It will be a little shallower than the septic tank, although it can be the same depth or slightly deeper. The proper depth of the septic tank is up to 4 feet. It’s possible that your local regulatory agency requires a certain depth for your drain field.

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.
