"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 size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

On average, you should call a pro to pump your cesspool once per year. If you have a larger home with a lot of family members, you may need to pump more (up to six times per year). On the flip side, if you’re talking about a cesspool for a home you don’t use much or if you’re the only occupant in a home, you won’t have to pump nearly as much.

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

Rainwater doesn't have a direct impact on the amount of water in your well. Instead, the majority of rain runs off into other bodies of water such as streams, rivers, and lakes. These bodies of water may sometimes function as the area’s reservoir and create aquifers, which then help to replenish your well.
