"This was the 1st time using this G-septic as the other company we have used in the past appears to not be in business anymore. Was thoroughly impressed by the services we received, we had them pump our tank and after they finished they noticed my main pipe entering the tank was cracked. They were able to not only let us know of the need for a repair but gave us a price to fix it. He dug out the trench and quickly fixed it at a very very reasonable price. Super pleased, had a great conversation with Edgar the owner while he was onsite turns out this man who looks to be in his late 20's has been doing this work for 20 years and boy you can tell, he is so knowledgeable, sure glad we stumbled upon him when we Google searched septic pumpers."

"They are family owned and operated. Jorge was very friendly and professional, and did everything to help. They even moved the tops of the tanks that must have been over a hundred pounds to a different location and installed Risers. We had to find where the septic tanks were, and what type of tanks, and what was needed to bring the tanks up to code. So we can sell the property. We would recommend them to anyone."

Septic Tanks questions, answered by experts

The best times of year to empty or pump a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access and the waste less likely to be frozen. Pumping before summer also helps avoid conflicts with vacations or outdoor gatherings. Fall is another great option, as contractors may be less busy, and servicing the tank can reduce the risk of overflow from winter and spring precipitation. While summer is also a suitable time, winter is generally not recommended due to frozen ground.

Leach lines are commonly made of PVC pipe, and they’re placed into trenches filled with gravel and sand, which help treat the wastewater. The PVC pipes are perforated, or drilled with small holes, so the wastewater can drain out of the pipes and into the surrounding material, which eventually leads to the aquifer.

If there’s a problem with your sewage system, you might notice water pooling on the ground around the tank, which could indicate an overflow. Clogged and sluggish drains or foul smells coming from your plumbing are also signs that there might be a blockage in your septic system.

Yes, a septic tank can get full. If this happens, you might run into issues flushing your toilets or draining your sinks. You may also notice your pipes making gurgling noises or the smell of sewage floating around your house. Other signs of a backed-up septic tank include water pooling or fresh, healthy grass growing above your drain field.

Septic tanks appear full after pumping because the liquid levels have returned to normal. If you can see the pipe, the tank is empty. However, heavy rain can cause septic tanks to fill faster than normal. You might also have leaky pipes or faucets, causing extra water to drip down the drains and into the septic tank.
