About this service

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.

What indicates my septic drain field needs attention in San Antonio?

Signs your septic drain field needs attention in San Antonio include persistently soggy or wet areas above the drain field, even when it hasn't rained. You might also notice a sewage odor, or wastewater backing up into your home. Unusually lush and green patches of grass over the drain field can also be an indicator of system issues. A specialist can diagnose the problem.

What kind of toilet paper is best for septic systems in San Antonio?

The best toilet paper for septic systems in San Antonio is any brand labeled as 'septic-safe' or 'biodegradable.' These products break down quickly in the tank, reducing the risk of clogs and buildup. Avoid using thicker, multi-ply papers or those with excessive dyes and fragrances. They can take longer to decompose and potentially cause problems for your system. Using the right paper helps.
