"My septic tank was over flowing. The drain pipe was obstructed. I call my normal guy on Thursday no response. Friday came and went. Saturday, still no response. Went to Home Advisor and with in an hour Innovative called and gave me a time they would be there. They pumped the tank and cleared the drain pipe. I was expecting a major expense but they were just fifty dollars more than the regular guy - who still has not responded to voice messages left on his emergency number. I appreciated the quick response, the complete job, and a reasonable price. I will be using the company going forward. Exceptional customer service."

"Mariano (spelled phonetically) contacted me right away. He diagnosed my issue over the phone and quoted a price. We scheduled a time for him to come out same day, arrived before appointment time, and removed/installed new sump pump (we purchased the sump pump before his arrival). He completed the work in the same day in a timely fashion and we paid as quoted. Thank you."

"Excellent work. He covered his shoes while walking in the house. Before starting the project he analyzed the whole tubing route of the sink all the way to the basement. Cleaned up the whole area after the job was completed. Professional work ethics."

I can t say this if many contractors ... totally satisfied with their work!"

Septic Tanks FAQs, answered by experts

Several signs can indicate a faulty well pump pressure switch. These include your pump running continuously, the pump not turning on at all, or a sudden and complete loss of water. Other symptoms are weak water pressure or an erratic, unpredictable water flow from your fixtures. If you notice these issues, the pressure switch may be the cause. Testing the switch can help diagnose the problem. A faulty switch will likely need to be repaired or replaced. If the issue is more complex, it's best to consult a professional well technician to ensure your water supply is restored correctly.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

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

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.
