"Excellent! Marty and his partner definitely know septic systems and how to evaluate their functioning level. We were very pleased and impressed with their knowledge, work ethic and the time they spent carefully checking every part of our system and explaining what they found to us. I will definitely use them again and tell neighbors as well. Several folks in my neighborhood tried going with the lowest bids on septic issues and all three had major repercussions! It pays to hire high quality people."

"Our existing septic tank was only a few years old, but the associated drainfield was failing and required replacement. Due to a small lot, our options were limited; but rather than a huge and unsightly bottomless sand filter, we opted for a less obtrusive (but expensive) treatment unit and pumps along with the needed replaced drainfield. Cory was very helpful in explaining complex options and costs."

"They put in new drains and a dry well for our driveway, carport, and front yard. When the first dry well wasn't large enough to hold all the runoff from a heavy storm, they came back and added a second for free. Excellent customer service, very responsive, good work."

Septic Tanks questions, answered by experts

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.

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.

There should be a red button or an on/off switch on or in your box. Press the button or flip the switch, then turn it back on by doing the same action again. If this doesn’t work, reset the breakers inside the box by flipping them off and back on again. After this, your alarm should stay off if there’s nothing wrong with your system. However, if the alarm is still sounding and there’s still a red light on, it’s time to call a pro for a diagnosis.

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.
