Septic System Maintenance Tips for Homeowners in Milton

If your home in Milton or the surrounding area runs on a septic system, proper care is essential to avoid messy and costly problems. With some simple routines and awareness, you can extend the life of your system and keep it running smoothly. Here are four key things every homeowner should know about septic system maintenance.

How to Tell if Your Septic Tank is Full

It can be tricky to know when your tank needs attention. Common signs include:

  • Drains emptying slowly in sinks, tubs, or toilets
  • Gurgling sounds in your plumbing
  • Wet spots or foul smells in your yard near the tank
  • Sewage backing up indoors

If you notice these warning signs, it’s time to call in a licensed plumber before the problem gets worse.

The Do’s and Don’ts of Septic System Care

Taking care of your septic system doesn’t have to be complicated. A few smart daily habits can make all the difference in how long your system lasts and how well it works.

The Do’s

  • Use water wisely. Spread out showers, dishwashing, and laundry loads so your system isn’t overloaded all at once.
  • Fix leaks quickly. A dripping faucet or running toilet can waste hundreds of litres of water, adding unnecessary stress to your tank.
  • Protect your drain field. Keep heavy vehicles, sheds, or paved surfaces away from the area so the soil can properly filter wastewater.

The Don’ts

  • Don’t pour grease or oil down the drain. These can harden inside your pipes and create blockages.
  • Don’t use harsh chemicals. Bleach, drain cleaners, and strong disinfectants kill the helpful bacteria your septic system relies on to break down waste.
  • Don’t flush non-biodegradable items. Wipes, paper towels, or hygiene products can clog pipes and fill up the tank too quickly.

By sticking to these simple do’s and don’ts, you’ll make septic system maintenance much easier and reduce the chance of costly repairs.

What Not to Flush or Drain with a Septic System

Certain items belong in the trash, not your pipes. Avoid flushing or draining:

  • Wipes (even “flushable” ones)
  • Paper towels and feminine hygiene products
  • Cat litter or coffee grounds
  • Paint, pesticides, or cleaning solvents

These products don’t break down easily and can clog or damage your septic system.

How Often Should You Pump Your Septic Tank

Pumping your septic tank is one of the most important parts of septic system maintenance, but many homeowners aren’t sure how often it needs to be done. The truth is, there isn’t a one-size-fits-all answer. The timing depends on several factors:

  • Household size. More people in the home means more wastewater flowing into the tank, which fills it up faster.
  • Water use. Families who do frequent laundry, long showers, or heavy dishwashing will need to pump more often.
  • Tank size. Smaller tanks reach capacity more quickly, while larger ones can go longer between pumps.
  • Type of waste. Homes that put a lot of grease, solids, or non-flushable items down the drain will also need more frequent service.

As a general guideline, most households should schedule a pumping every three to five years. However, the best way to know for sure is through regular inspections. A licensed plumber can check your system, measure sludge levels, and recommend a schedule that fits your home’s needs.

Staying on top of pumping prevents backups, protects your yard, and ensures your septic system works reliably for years to come.
