What happens if I never pump my septic tank?

Solids overflow into the drain field, clogging it permanently. Drain field replacement costs $5,000-$20,000. Regular $300-$600 pumping prevents this catastrophic and expensive failure.

Can I pump my own septic tank?

No. Septic pumping requires a vacuum truck, proper licensing, and legal disposal at an approved facility. The gases inside a septic tank are toxic and can be lethal. Always hire a licensed professional.

How do I find my septic tank?

Check your property records or as-built drawings. Look for a clean-out pipe in the yard, or follow the sewer line from where it exits the house. Septic companies can locate tanks with electronic probes for $50-$150.
