"The repair work was well done. I had no idea it would take 2 people. The first quote was for a lower price but then they did not have the parts so I said OK to the more expensive option. But then they were not able to do the more expensive option so they went and got the part for the lower price option. But ultimately they charged me for the higher price option. I have called three days in a row and have not been able to resolve the price discrepancy."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

Septic Tanks questions, answered by experts

The right psi for your well pressure tank depends on the tank’s pressure settings. For instance, if yours is set to 30/50 psi (which is common), the ideal psi is 2 to 3 psi below the cut-on pressure—in other words, 27 to 28 psi. However, if it’s at a higher setting of 40/60 psi, 38 psi would be the appropriate level.

You may want to increase the size of your leach field, for instance, if you add on to your home or install more bathrooms in your house. You can make your leach field larger by installing more pipes or expanding the area of the field itself. Improving the soil quality in the drain field can also make it more effective without increasing the area.

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.

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.

Ensuring you have adequate space for your engineered septic system is crucial. You’ll need to reserve approximately 900 square feet for a three-bedroom home’s system. However, the type of soil you have, soil absorption rate, the size of your home, climate, and local zoning code will impact the actual amount of space you need.
