"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

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.

When your septic system is failing, you’ll probably smell it. Common signs of a septic system failure include sewage odors in the home or around the yard, flooding in the yard above the septic tank or in the leach field, and wastewater or even raw sewage backing up into your home’s drains.

Regular checks of pressure tanks, testing water quality, and cleaning intake screens.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

Yes, it is generally okay to oversize a well pressure tank, and it will not harm your well system. The primary advantage is that a larger tank reduces frequent pump cycling, leading to longer, slower cycles with fewer startups. This can result in less wear and tear, potentially increasing the lifespan of the pump and conserving energy. However, there are drawbacks to consider. Oversized tanks have a higher upfront cost and require more physical space. While not necessarily a bad thing, opting for a tank that is appropriately sized for your well is often the most efficient choice in terms of cost and space.
