"Luis Septic Service agreed to replace our septic ejection pump and tank alarm with the pump and alarm switch I had purchased. As we tested together we agreed that the Alarm switch or circuitry was the reason the alarm had triggered and not because the tank had overflowed. I elected to replace the pump as the old one was 7 yrs old. We worked together and completed the project successfully ... $500"

"He did an excellent job replacing our septic tank. He solved a difficult problem with a huge boulder that was blocking the move of the tank. Also was very careful not to damage the rest of the yard during installation. Overall, job well done. Quality job at a fair price."

"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

"DEFINITELY RECOMMEND! Joe and Denise are very nice and easy to talk to. They listen to what you need and made sure you understand the plan before they do anything. We asked for extra work and are very accommodating. With regards to work itself, they took their time to do it right. With us, we had a last minute change of septic tank size and Joe was so nice to accomodate us. They did an excellent job with our septic system and will definitely recommend them. We also feel like we gain a friend!"

"He was on time, friendly, and honest. We had a plumber tell us that the pipe was broken at the septic tank so Phil and Mike came out to dig it up and replace it. When he dug it up he found that the pipe was not broken and was totally honest about it and gave us options and help that solved our issue we were having. I would totally use him again for any work I need done in the future."

Septic Tanks FAQs, answered by experts

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

Your garbage disposal will only affect the health of your septic tank if you’re using it too frequently, or filling it with organic waste that doesn’t fully break down. If the tank fills up with too many solids, the bacteria won’t have enough time to consume it before more is added, which can lead to an overflow in the drain field. Your tank will need to be pumped more frequently with excessive or improper garbage disposal use.

Although cesspits may be necessary depending on your main sewage system access or nearby soil quality, they carry a few drawbacks. Cesspools require regular emptying and have relatively high maintenance and pumping costs. Certain areas also disallow the use of cesspools and may require you to cover the cost of existing cesspools to be converted into septic tanks.

A well does not run out of water because the groundwater continues to refill with rainwater that seeps through the ground. If the well is too shallow or there is a drought, a well can run dry or be short in supply. It’s important to have a well deep enough to source enough water for your home’s use. Deeper wells tap into more groundwater reserves. If your well is not producing enough water, you may need to redig your well.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.
