Most Fraser Valley properties on septic should have their tank inspected every one to three years and pumped every two to five years. The right interval depends on tank size and the number of people in the household. A larger household generates more wastewater and fills a tank faster. Smaller tanks serving the same number of occupants need to be pumped more frequently than larger ones.

Skipping maintenance does not save money. Solids that are not pumped out accumulate, overflow into the drain field, and plug the absorption trenches over time. Drain field restoration is far more involved than a routine pump-out. Staying on a regular maintenance schedule is the most cost-effective way to protect your system.

Watch for these indicators:

1. Slow drains or backups throughout the house with no obvious clog
2. Gurgling sounds in your plumbing after flushing or draining
3. Wet, spongy, or unusually green patches of ground over the drain field
4. Sewage odours in the yard or near the tank access point
5. Sewage backing up into floor drains or fixtures

Any one of these warrants a call. Two or more at once means the system needs attention immediately.

Several habits accelerate wear on a septic system:

• Flushing non-biodegradable items such as wipes, paper towels, and sanitary products
• Pouring grease, cooking oil, or household chemicals down the drain
• Running excessive water loads in quick succession, which overloads the system
• Driving vehicles or heavy equipment over the drain field, which compacts the soil and crushes distribution pipes
• Planting trees or deep-rooted shrubs near the tank or field lines, since roots seek out moisture and can crack or block pipes

In most cases, no. Avoid commercial septic additives unless a licensed technician recommends one for a specific purpose. A well-maintained tank relies on naturally occurring bacteria to break down waste. Most additive products disrupt that balance rather than enhance it, and none of them substitute for regular pumping.

A few straightforward habits go a long way:

• Only flush toilet paper and human waste
• Spread laundry loads across the week rather than running multiple loads in one day
• Fix leaking faucets and running toilets promptly, because even a slow leak adds up and overloads the tank
• Keep the area over the drain field clear of vehicles, structures, and deep-rooted plants
• Keep a record of your pumping dates and inspection reports

We recommend scheduling an inspection before purchasing a property with a septic system. It is one of the most cost-effective pieces of due diligence a buyer can do.
