"Andrew did a great job fixed my upstairs toilet, had other plumbers try to figure out why the toilet wouldn't drain, Andrew used a camera in the main drain and found the problem. Awesome job, we are all set with the toilet and he checked the whole house for any other issues. We will use Andrew in the future, we highly recommend his services."

"Hayden first came because my septic overflowed a little--he found the blockage, fixed it, took a video of it so I could see it, and charged me very reasonably--on the weekend! Then he came back, did my Title V inspection and pumped me out. Again very prompt, thorough, meticulous. I highly recommend him. Easy to work with, reliable, *very* responsive."

"Sorry, looks like this review got stuck in draft mode for quite a while. But the good thing about that is everyone gets to read a review with an update 1.5 years later on the quality of the work completed! In late 2020 I had recently moved into my new home and the gas water heater wasn't working properly. It was leaky and at least needed the pressure relief valve replaced, but the tank was well past it's expected lifetime. The techs were very helpful, kind and knowledgeable. The valve replacement wasn't going to work because repairing the tank could damage it further, so the tank was replaced instead. The price was very reasonable and installation was done really well. They did a great job with cleanup too! One and a half years later and the tank has had zero issues! I would definitely recommend them for heavy jobs like this or more simple ones around the house. Thank you very much!"

Septic Tanks FAQs, answered by experts

The ideal depth of a septic drain field is 18 to 36 inches below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.

You can cover a septic tank riser with dirt, but it’s not always the best idea. If you have a plastic riser and you bury it, you can easily lose track of it since you won’t be able to find it with a metal detector. Make sure to clearly note where your rise is in your yard so that you’re able to access it easily the next time you or a septic pro needs it. Don’t bury the cover too deep or you could place too much stress on it and make it too difficult to access in the future.

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.

Adding a thin layer of dirt over a septic drain field is fine, especially if soil erosion has occurred. However, adding too much dirt can compact the soil, reducing the drain field’s ability to absorb and filter wastewater properly. Avoid using heavy clay soil, as it can prevent proper drainage. Instead, use a light layer of topsoil and plant grass to help with soil stability.

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.
