What affects the price

About this service

The price for a new septic installation depends on several key factors. The primary drivers are the number of bedrooms in your home, which determines the tank size, and the results of your soil percolation test. If the ground requires a specialized treatment system, the total will be on the higher end of the spectrum. Costs typically sit in a broad range depending on these site needs. Exact pricing confirmed free on the call.

Summer often means more houseguests and increased water usage, which puts extra demand on your septic tank. With more showers and laundry loads, it is easier for a tank to reach capacity. If you have guests coming over, consider a pump-out beforehand to avoid an inconvenient backup during your family gatherings.

Frequently asked in Pittsburgh

What is the purpose of a septic tank?

A septic tank functions as a mini wastewater treatment system for homes not connected to a municipal sewer. It holds sewage, allowing solids to settle and scum to float, while partially treated liquid effluent flows out to a drain field. This prevents contamination of soil and water sources. It’s a vital component for many properties.

What is the average cost of a septic tank?

How long do septic tanks usually last?

A well-maintained septic tank system can last for decades, typically 20-30 years or even more. Regular pumping, avoiding grease and harsh chemicals, and proper installation are key factors. The soil conditions and usage patterns also play a significant role in its overall longevity. Care is essential.

How often do septic tanks need to be emptied?

In general, septic tanks should be pumped every 3 to 5 years. This can vary depending on the number of people in your household and your water usage. Families in Pittsburgh homes with higher water consumption may need more frequent pumping. Regular inspections help determine the right schedule.

How much does it cost to have a septic tank pumped?

How often should a septic tank be pumped?
