"Really glad i found Best Plumbing. Hired them to replace a shower pan and liked them so much that I had them replace shower doors and put in a new water heater as well. Fair pricing and always prompt, it felt like they went over and above what I was expecting. I would not hesitate to recommend Best Plumbing to anyone!"

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks questions, answered by experts

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.

To keep roots from growing into a septic tank. However, there are other steps you can take if existing tree roots are getting close to your septic tank. For one, you can install root barriers, which physically block roots from reaching your septic tank. You can also use chemical solutions in your yard or plumbing system to deter root growth.

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.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

Regular checks of pressure tanks, testing water quality, and cleaning intake screens.
