Evergreen On Site is your local pumping expert, dedicated to educating our customers about the care that their systems require. Routine pumping and inspections are crucial to the life of your system, and in most cases can save you from costly troubles and repairs in the future. Based on average use, it is recommended that a system be pumped every 3-4 years. Average use is based on a 4 person residence using approximately 120 gallons of water per person per day. There are some conditions that will cause your tank to need pumping sooner, such as using a garbage disposal, excessive water usage, or leaky faucets or toilets. If you are unsure if your system needs pumping, please call our office today to speak to a septic professional or to schedule an appointment. You can also refer to the FAQ's below for answers to commonly asked septic questions.
It is recommended that you have your system pumped every 3-4 years, however, if you are unsure of the last service date, we can gladly come and check your levels to determine whether pumping is necessary.
The most common way to locate your system is to find the lid(s) for your tank out in your yard. Most of the time they are round, concrete or fiberglass, and are level with your yard. Sometimes the lids are not on risers, therefore are not at surface level. In cases where you cannot find your lid, you can contact your local health department to obtain an "As-Built" (a drawing of your septic system) that will show where your system is located. (Please see our links page for contact information for the King or Snohomish County Health Departments).
Your pump tank will not fill as often as your septic tank; however, we recommend that they both be pumped at the same time to keep your system free of any build up and in proper working order saving you both time and money.
A full pump tank could indicate that your septic tank is full or that your pump is not working properly. We recommend you have a technician come and advise your best course of action in these cases.
If you see liquid bubbling up out of the lid on your tank, if your toilets gurgle when flushed, or if your fixtures are slow to drain, this could be an indication that either the tank is full or the filter inside the tank is clogged. If you experience any of these problems, please contact us right away.
