"Caccia ran into an unexpected underground obstacle while replacing our sewer lateral. They set up a temporary sewer line so we could use our home while they used additional labor and equipment to complete the project. Caccia honored the original quote amount with no upcharges for the extra work required. Caccia handles contingencies well. We have used them in the past and we will use them in the future."

Septic Tanks questions, answered by experts

The average lifespan of a deep well pump is between 15 and 25 years, after which you’ll have to replace it. Several factors can affect the lifespan of a well pump, such as the quality of the unit. Proper maintenance and repair can also help extend your well pump’s lifespan as well as keep adequate water flow and pressure throughout your home.

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.

It is not normal to smell your septic outside and indicates a problem such as an unsealed manhole or access lid, a clogged septic line, a faulty vent stack, or the need for a septic tank pumping. If sewage is leaking from your septic system, it can be hazardous to you, your family, pets, and the surrounding environment. You can troubleshoot the issue yourself, or contact a septic tank pro who can resolve the issue quickly.

Most deep wells can be expected to last somewhere between 30 and 50 years. This assumes that the well and all of its components are properly maintained on a regular basis. During this time, it is unlikely that modern deep wells will run dry over the course of their typical lifespan. That is one of the biggest benefits of digging a deeper well. 

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.
