"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

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

Septic tanks and cesspits are both types of sewage and wastewater systems, but they differ in key ways. The main difference between the two systems is that septic tanks separate sewage from wastewater and allow the latter to flow into a drainage field to filter and disperse into the soil. Cesspits don’t have outlets and instead, store sewage until it needs to be pumped by a professional.

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.

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product. 

Septic drain fields should be at least 10 feet from the property line, though exact requirements vary by location. Some areas may require further distances, such as 25 feet or more, depending on soil conditions and local health regulations. This extension ensures proper wastewater absorption and prevents contamination of neighboring homes.
