"They were hired initially to repair the drain field. Shortly thereafter, we discovered I needed a new tank. I don't think a new tank should have cost me $2,500 but at that point into the project, you really have no choice. After checking around, most places sell a new tank between $900-1500. Also, the extra dirt that was not used to refill the holes was left in the center of my yard along with the brick/cinder blocks from the old septic system. He did level off the mound of dirt however, it was a 5 inch mound approximately 10 ft. in diameter in the middle of my yard. I have now been shoveling dirt to try and spread it out evenly over my yard, as well as, removing the old debris. So far, the septic system is still working"

"Washington Boyz Construction,LLC got off to a rough start with work ethics and implementing/maintaing professional standards (i.e. beginning project on/about negotiated day/date, consistent verbal/written communications, consistently working daily when weather permitted, initiating thorough inspection w/questions re: work/materials required upfront w/o assumptions, providing detailed contract w/approx. start/completion dates and cost, etc.). However, these things did improve throughout duration of project and company did an excellent job with cleaning up work areas when work was finished each day. Very pleased with craftmanship of finished project (e.g converting carport into garage & installation of front entry door) and am loving the conveniences & technological features of the newly installed garage. Friends/associates are also very impressed with the craftmanship & tech. functions of the garage. Although Washington Boyz Construction, LLC and I did have differences following completion of project in relevance to a few observable flaws resulting from incomplete finishings plus one newly occurring issue, the owner of company (Dennis Washington) corrected issue(s) and at that time our professional relation was also reconciled."

Septic Tanks FAQs, answered by experts

Your septic tank naturally contains the beneficial bacteria it needs to function, so you typically don't need to add more. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three overripe tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many experts consider them unnecessary and potentially harmful. The most effective way to maintain a healthy bacteria population is to avoid using chemical drain cleaners, which can kill the good bacteria in your system.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

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.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.
