Winter Septic Care in Northern Nevada

Why septic freezes

Septic systems freeze when water sits still in shallow lines, when snow cover is packed down by cars or foot traffic, or when a house sits empty. Second homes and rentals are most at risk.

Winter checklist

• Pump in fall, not January.
• Don't drive, park, or plow over the tank or drainfield.
• Let snow sit on the drainfield. It insulates.
• Fix running toilets and dripping faucets that trickle cold water into lines.
• Mark the lids with a tall stake so they can be found under snow.
• If you leave for weeks, have someone run water daily.

If it freezes

Don't use antifreeze or salt in the system, and don't build a fire over the tank. Call a pro. Line jetting with warm water or adding heat tape may be needed.
