What affects the price

We also look at the accessibility of your tank lids; if they are buried deep underground or hidden under landscaping, extra labor is required to reach them. The distance from our truck to the tank also impacts the setup time. Every property has unique plumbing needs, and exact pricing is confirmed free on the call.

Frequently asked in Philadelphia

What is the purpose of a septic tank?

A septic tank is an underground wastewater treatment structure that serves homes not connected to a municipal sewer. It separates solids and scum from liquid wastewater, allowing for partial decomposition. The effluent then flows to a drain field for further treatment in the soil.

What is the average cost of a septic tank?

How long do septic tanks usually last?

With regular maintenance, such as pumping every 3 to 5 years, septic tanks can last for 20 to 30 years, and sometimes even longer. Consistent upkeep is essential to prevent solids from accumulating and causing system failures. Proper care significantly extends the life of your system.

How often do septic tanks need to be emptied?

Septic tanks typically need to be pumped every 3 to 5 years. This frequency is determined by the tank's size and the household's water usage. Homes in the Philadelphia area with more occupants or higher water consumption might require more frequent pumping to maintain optimal performance.

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

How often should a septic tank be pumped?

A general guideline is to pump your septic tank every 3 to 5 years. However, if your household uses a lot of water or has many residents, you may need to pump it more frequently. This prevents solids from building up and potentially causing blockages or system damage.
