"After a phone call with a representative that called me and discussion of the work I was looking for, and mentioning a number of times the work involved a site visit was scheduled. When the service person came to do an onsite evaluation, I was told: 'we don't do oil tank removals and installs.' Representative was obviously not trained for what I had requested during our phone conversation and that Nicholson Heating, Cooling, Plumbing and Electrical didn't do this service or wasn't informed of it during training."

"At first it was suggested that the whole commode be replaced, but it was found out that the bowl was intact and that only the tank be replaced. This replacement was done and the new unit worked fine and nothing else was needed to be done. Great service, good workmanship and will recommend this company to others."

"Very knowledgeable and friendly. Most importantly, I didnâ t feel as though I was being pressured into repairs or services I didnâ t need. If your looking for an honest company I recommend having S&G look at any septic problems orTitle V you may need."

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.

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. 

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.

Baking soda does very little to nothing for a septic tank, but it can help unclog a drain or clean out a garbage disposal. Rotten tomatoes and yeast are the best ways to increase the bacteria in your septic tank naturally. You can add these to your system once every three months.

Having a well means that a household’s water supply, including water that comes through faucets, showerheads, and appliances, is supplied through a private source rather than from a city. The well pulls fresh water from an underground water supply, such as an aquifer, and the well pump pushes the water from the well to your household.
