"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."

"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

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.

A septic tank lid is often 1 foot underground, but it could be just 4 inches from the surface or 4 feet deep. For septic tank lids that are closer to the surface, you’ll have an easier time locating them just by looking for signs in the yard or using a metal probe. But for septic tanks that are buried deeper underground, you’ll need to hire a pro with specialized equipment to track down the lid without risk of damaging utility lines.

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

Septic systems typically require servicing every 3-5 years, but frequency varies according to household size and tank capacity.

There are a few things that can make your drain field fail. These include driving or parking vehicles or heavy machinery on the field, excess sodium in the soil, or having a high water table. You can prevent failure by ensuring your installer checks that your chosen location is suitable for a drain field and properly maintaining your system with the help of a professional.
