Your septic system plays a critical role in protecting your home, property, and groundwater—but it’s often out of sight and out of mind. At Allied Septic, we believe informed homeowners make better decisions and avoid costly repairs.
Below are answers to some of the most common septic system questions we hear from homeowners across New Hampshire.
A septic system treats and disposes of wastewater from your home. Wastewater flows from your plumbing into a septic tank, where solids settle and separate. Liquids then move into the leach field, where the soil naturally filters and treats the water.
When properly maintained, a septic system can last 20–30 years or more.
Most septic tanks should be pumped every 2–3 years, but the exact schedule depends on:
• Household size
• Tank size
• Water usage
• Use of garbage disposals
Routine pumping prevents solids from entering the leach field, which is one of the leading causes of septic system failure.
Tip: Delaying septic pumping is one of the most common—and costly—mistakes homeowners make.
Common warning signs include:
• Slow drains or frequent backups
• Gurgling sounds in plumbing
• Sewage odors inside or outside the home
• Standing water or soggy areas near the leach field
If you notice any of these, it’s important to schedule service right away to avoid damage.
Your septic system is not designed to handle everything that goes down a drain. Avoid flushing or draining:
• Wipes (even “flushable” ones)
• Feminine hygiene products
• Paper towels
• Grease, fats, and oils
• Harsh chemicals or drain cleaners
• Coffee grounds or food scraps
These items can clog pipes, damage bacteria levels, and shorten the life of your system.
Septic additives are not a substitute for pumping or professional maintenance. In some cases, additives may actually harm your system by disrupting natural bacteria or forcing solids into the leach field.
The most effective septic maintenance plan includes:
• Routine pumping
• Smart water usage
• Professional inspections
You can protect your septic system by:
• Scheduling regular pumping and inspections
• Fixing leaky faucets and toilets promptly
• Spreading out laundry loads
• Avoiding parking or driving over the leach field
• Keeping trees and roots away from system components
Preventive care costs far less than system replacement.
A failing septic system can:
• Damage your property
• Contaminate groundwater
• Create health risks
• Result in expensive repairs or replacement
Early detection and routine maintenance are key to avoiding emergencies.
Yes. Freezing temperatures can impact septic systems if they are not properly insulated or maintained. Consistent use, adequate snow cover, and regular service help prevent winter issues such as frozen pipes or tanks.
You should contact a septic professional if:
• It’s been more than 2–3 years since your last pumping
• You’re experiencing backups or odors
• You’re buying or selling a home
• You’re unsure of your system’s condition
