How Often Should I Have My Tank Pumped?

The frequency at which you should have your holding tank pumped can vary depending on several factors, including the size of the tank, the volume of waste it receives, and the specific regulations or guidelines in your area. As a general guideline, it is recommended to have your tank pumped when it reaches approximately 75% to 80% of its capacity.

When Should I Get My Tanks Pumped?

  • Slow Drains: If sinks, toilets, or drains are slow to empty, it may indicate a full septic tank.
  • Odors: Foul smells near drains or in the yard could signal a full or failing septic tank.
  • Backup or Overflow: Wastewater backing up into sinks, toilets, or pooling in the yard is a clear indication of a full septic tank.
  • Lush Grass or Algal Blooms: Unusually vibrant patches of grass or excessive plant growth may indicate septic tank issues.
  • Gurgling Sounds: Gurgling or bubbling noises from drains may suggest a full septic tank affecting the drainage system.
  • Sewage Backup in Appliances: Sewage backing up into the washing machine or dishwasher while in use points to a full septic tank.

When Should I Get My Toilet Pumped?

Regular pumping of portable toilets is essential for cleanliness and functionality. Pumping should be scheduled when the toilet is around 75% full or as per specific requirements.

When Should I Get My Trailer Pumped?

The frequency of pumping depends on factors such as usage, size of the trailer, and the number of occupants. As a general guideline, it is advisable to pump the trailer when the holding tank reaches approximately 75% capacity.
