"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

An outdoor water valve typically has a round or oval handle that you can turn to control the water flow. It may be located in a protective box or pit near the property line, where the main water line connects to your house.

Most homeowners know there’s a septic system problem when they can smell one. However, this isn’t exactly a scientific deduction method. Consider some of the other signs: standing water or constantly damp earth in the drainage area, toilets and sinks that won’t drain or frequently back up, and loud plumbing. You really need to be on top of routine maintenance with septic systems in order to avoid such unpleasant symptoms of a septic issue. 

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.

With so much available information about the ecological effects of cesspools (and their general unpleasantness), it begs the question: Are cesspools legal? In short, sort of. Large-capacity cesspools that serve more than 20 people are completely illegal countrywide. Existing, smaller cesspools are generally allowed as long as they’re not actively polluting. However, new cesspools are illegal to build in all 50 states and Puerto Rico, and many states offer programs to help homeowners with the costs of updating cesspools to modern septic systems.

Many variables, such as home size, type of engineered system, the material used, soil conditions, and water usage, dictate how long your system will last. On average, most homeowners find that their system lasts 15 to 20 years, though it’s not unheard of for them to last up to 40 years with annual and preventative septic maintenance.
