How often does my septic tank need to be pumped?
Four major factors influence the frequency of septic pumping:
• Household size
• Total wastewater generated
• Volume of solids in wastewater
• Septic tank size
Time is a dangerous determiner for deciding when to pump a septic tank. If tank usage falls outside the averages a wrong guess can lead to a very costly tank and or drain field repair or replacement.
Typically, a 3 to 5 year pumping schedule is recommended by everyone from the EPA to The National Association of Wastewater Technicians (This is the association that trains all the septic pumper technicians across the country). Their primary business is pumping tanks. They recommend a time determiner between pumping BUT THE DO NOT USE TIME. They all use the only proven method of determination which is to physically put a pipe into the tank and check the sludge level. Any other method is just a guess. If you do hire a professional to inspect the tank, insist they physically inspect the sludge level, or do it yourself. IT IS VERY EASY TO DO. Just follow the simple instructions given under Does my septic tank need to be pumped? and watch the accompanying video. This process only takes a few minutes and you will know for sure if it needs pumping. If you cannot find or access the holding tank, the next best thing is to add a liter of TankTechsRx for Septic Systems to the tank immediately. If you suspect there may be a problem, add two liters the first time and then one liter per year. It will not cure mechanical problems, but it will take care of the Solids in the tank and the scum in the drain field.
