"GREAT! Danny was on time, polite and calm - which is a big deal with our dog, who is excitable. Turns out the filler was spraying water on the back of the tank inside and sometimes it was coming out of the tank. There was no dampness anywhere else, and the seal between the toilet tank and base was so solid it was actually dusty. So he adjusted the water level, tightened the toilet seat and insisted we call if there were any further problems. NO CHARGE!!! We are going to need a new water heater one of these days, so we will definitely call these guys back for that."

"The whole process was very smooth. They came out and spent a couple of hours assessing the problems...turns out we had several. The water heater burner had failed and was under warranty. But they also discovered our pressure regulator had failed, our gate valve was frozen, and we had a pipe leaking in the wall! They found the necessary part for the warranty repair and drove 50 miles each way to get it rather than make us wait 1-2 days for for the part to be shipped. They stayed until all the problems were resolved which was greatly appreciated! (My wife and three daughters were not relishing cold showers!)"

Septic Tanks FAQs, answered by experts

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

Common signs that a septic tank is full include plumbing issues, odors, and changes in your yard. You may notice wastewater or sewage backing up into your home's drains, or that sinks, tubs, and toilets are draining slowly. Gurgling or bubbling sounds from the pipes are also a key indicator. Outside, you might smell foul sewage odors around your house or the septic tank area. Look for pooling water, spongy soil, or a marshy environment around the drain field. Another tell-tale sign is a patch of grass over the septic system that is suddenly lusher and greener than the rest of your lawn. If you notice any of these signs, you should contact a septic professional for an inspection and pumping.

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

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.

Deciding between an engineered septic system and a conventional one depends on property size, soil quality, local regulations, and environmental factors. If your property has limited space, poor soil, or is close to sensitive environmental features, an engineered system may be required. Professional site evaluations, considering water usage, long-term plans, and budget constraints, can help determine the appropriate choice. Consulting with a septic system professional is crucial for ensuring compliance with regulations and selecting the best system for your property's unique needs.
