"Excellent service! Called promptly. Arrived at time specified with crew. Pulled old pump and replaced pressure tank by early afternoon. From first contact to completion of project was less than 24 hours. When you have no water time is important. I’d recommend them."

"Bought a faucet at Lowe's. After looking at the connections for a pedestal sink, I decided to have this one professionally installed. It was a two hour procedure for a professional plumber. Though not a difficult job for a plumber, everything about the job was very professional. Appointment was confirmed. A telephone call was provided giving an update of when the plumber would arrive. Kevin was the name of our plumber. He was very courteous. He covered our floor, wore shoe covers, cleaned up afterwards. He checked the plumbing for leaks and drainage. Contracting the way it should be."

"Joe helped us design an extension and stairs to our existing composite deck. Our house is in a condo community and we were restricted in the amount of space we were allowed to use. He was creative in figuring out how to get the best design. He and his crew are very professional, courteous and neat. Beautiful work. We love our deck. I would definitely recommend this company."

Septic Tanks questions, answered by experts

A well does not run out of water because the groundwater continues to refill with rainwater that seeps through the ground. If the well is too shallow or there is a drought, a well can run dry or be short in supply. It’s important to have a well deep enough to source enough water for your home’s use. Deeper wells tap into more groundwater reserves. If your well is not producing enough water, you may need to redig your well.

Watch for slow drainage, pooling water in the yard, or unpleasant odors inside or outside. Addressing these issues timely avoids significant disruptions or costs.

Adding a thin layer of dirt over a septic drain field is fine, especially if soil erosion has occurred. However, adding too much dirt can compact the soil, reducing the drain field’s ability to absorb and filter wastewater properly. Avoid using heavy clay soil, as it can prevent proper drainage. Instead, use a light layer of topsoil and plant grass to help with soil stability.

There are a few signs that indicate a failing drain field. For instance, if your septic tank starts requiring more pumping than normal, your drain field might be failing. Other signs to watch for include poor drainage after rain, standing water or sewage over the septic system, a strong septic smell outside, new and healthy grass growing over the drain field, and plumbing backups in your sinks, bathtubs, or toilets.

Most septic tanks can handle two to three loads of laundry per day, or a weekly total of between seven and 10 loads. Although septic systems do require homeowners to be somewhat careful with their plumbing systems—for instance, it’s not a good idea to flush a bunch of toilet paper all at once—they can still handle fairly heavy use.
