Frequently Asked Questions

How often should I have my septic tank pumped?

Most residential tanks should be pumped every 3 to 5 years, depending on household size and usage. Regular maintenance prevents solids from escaping into your drain field.

What are the signs that my system is failing?
Keep an eye out for slow drains, gurgling sounds in your pipes, lush green grass over the drain field (even in dry weather), or unpleasant odors around your yard.
Can I use additives to avoid pumping?
While some additives can help break down waste, they are not a substitute for physical pumping. Only pumping removes the inorganic sludge and scum that can eventually clog your system.
