"This is the best business we have ever worked with! Sean was responsive, professional and incredibly helpful every step of the way. He is very knowledgeable of what needs to be done, and educates you throughout the process. Our job (the installation of an EPA septic system) was completed quickly, efficiently, and without incident. We had to contact numerous companies to work toward getting this job done. Many didn't even return calls. Many were unresponsive once they had been out. Two acted as though we were at their whim and totally unimportant. P&G appreciates, respects and works to do all they can to HELP their customers. We are so pleased with their business acumen! Hiring P&G for your job will be the best move you could make! Amazing work, fair pricing, and the most pleasant to work with!"

"Josh Smith from J& R Drain Service was one of the most honorable plumbers I've met in a long time. We have a rental property in an old beautiful home in a historic district in Dayton. Our water heater burst and our tenants were scrambling to save their things from water damage and ruin. We didn't know what to do so we posted on Home Adviser but called R*** R***t** to get emergency services. Less than 2 minutes after I made the call to R**R***, Josh Smith from J&R called me. The guy from RR was great and knowledgeable but his prices were outrageous! I called Josh S back and offered him a chance to bid. He agreed to do the service for the price I was willing to pay, which was $500 less than RR! He even came back the next day to do extra work. He treated my home like he was working on his own. I'm very grateful to have found him I appreciate Josh and J&R. Thanks Josh, I owe you a beer!"

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks FAQs, answered by experts

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.

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

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.

Several warning signs can indicate current or future issues with your well pressure tank. If you notice inconsistent water pressure, water spitting from your faucets, clicking sounds, or electricity bill spikes without other obvious causes, it may be time to get your pressure tank and well system looked at by a professional.

The efficacy of a drain field depends on a wide variety of factors, though a well-maintained one can last as long as 40 or 50 years. Of the different types of septic tanks on the market, concrete and plastic tanks tend to last the longest—upwards of 40 years if they’re pumped regularly—while steel tanks have a tendency to rust over time and may need to be replaced after 15 or 20 years.
