What affects the price

The final bill for septic work depends on a few specific variables. First, the size of your tank and the total volume of waste removal play a role. 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 Seattle

What's the best toilet paper to use with a septic system in Seattle?

For septic systems in Seattle, it's recommended to use toilet paper specifically labeled as 'septic-safe' or 'septic-friendly.' These products are designed to break down quickly and easily in the septic tank, reducing the risk of clogging the system. Avoid using excessive amounts of any type of toilet paper, and never flush paper towels, "flushable" wipes, or feminine hygiene products, as these can cause significant problems. The pros can advise on specific product types.
