"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."

Septic Tanks FAQs, answered by experts

Concrete septic tank risers are heavier and more durable than plastic or fiberglass ones, making them suitable for long-term use. Installing a concrete riser differs from installing plastic or fiberglass risers primarily in the materials and methods used. The process involves cutting the concrete risers to the required length and then stacking them, using concrete sealant or adhesive between sections for secure attachment. Due to their weight, extra care is necessary during leveling and the attachment of sections. Concrete sealant or adhesive may also require a curing before the riser is ready for use.

Septic tanks and cesspits are both types of sewage and wastewater systems, but they differ in key ways. The main difference between the two systems is that septic tanks separate sewage from wastewater and allow the latter to flow into a drainage field to filter and disperse into the soil. Cesspits don’t have outlets and instead, store sewage until it needs to be pumped by a professional.

Depending on the size and location of your septic tank repair job, you may want to let the septic pros finish before tackling other backyard work. However, in some cases, it’s not a bad idea to coordinate between your providers if the timing’s right and your septic repair pro says it’s safe to do so. For instance, if the septic repair work is happening in the fall, you might want to take advantage of the opportunity to prepare your backyard landscaping for winter , or in spring, start mulching the garden beds.

A properly installed and maintained septic drain field (also known as a leach field) can last up to 50 years, though the average is around 20 years. However, factors like poor soil conditions, heavy usage, or improper maintenance can significantly shorten its lifespan to 15-20 years.

To extend the life of your drain field:

  • Schedule Regular Inspections: Have the entire septic system, including the drain field, inspected every two to five years to catch problems early.

  • Protect the Area: Avoid driving heavy vehicles or placing heavy structures over the drain field. Plant only grass or other lightweight vegetation with shallow roots over the area.

  • Maintain the Septic Tank: Proper care of the septic tank, including regular pumping and avoiding harmful chemicals, prevents strain on the drain field.

Be aware of signs of failure, such as strange odors, standing water, or unusually lush grass over the field, which indicate your system may need professional attention.

There are many potential causes of low well water pressure. The most common include sediment buildup, leaking pipes, a failing well pump, or a cracked pressure tank.
