"GREAT! Danny was on time, polite and calm - which is a big deal with our dog, who is excitable. Turns out the filler was spraying water on the back of the tank inside and sometimes it was coming out of the tank. There was no dampness anywhere else, and the seal between the toilet tank and base was so solid it was actually dusty. So he adjusted the water level, tightened the toilet seat and insisted we call if there were any further problems. NO CHARGE!!! We are going to need a new water heater one of these days, so we will definitely call these guys back for that."

"The whole process was very smooth. They came out and spent a couple of hours assessing the problems...turns out we had several. The water heater burner had failed and was under warranty. But they also discovered our pressure regulator had failed, our gate valve was frozen, and we had a pipe leaking in the wall! They found the necessary part for the warranty repair and drove 50 miles each way to get it rather than make us wait 1-2 days for for the part to be shipped. They stayed until all the problems were resolved which was greatly appreciated! (My wife and three daughters were not relishing cold showers!)"

Septic Tanks FAQs, answered by experts

Schedule annual inspections, test water pressure, and protect the pump from freezing temperatures.

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.
