The information below can help you make your backyard pool safe and fun for everyone. The content was developed as a partnership between the Brant County Health Unit and Canadian Red Cross Water Safety Services (Brantford).

Your Guide to Safe Pool Fun

  • Pool safety check: essential before EVERY swim

  • Injuries and accidents: preventable

  • Safe and fun pool environment: your responsibility

 Circulation and Filtration

Pool filter basics:

  • Remove colour, suspended particles, organic material and some bacteria
  • Boosts effectiveness of sanitizers like chlorine
  • Run filter 24 hours/day, seven days/week for best effectiveness

Backwash and Downwash

  •  Begin backwash when pressure difference between influent and effluent pump lines reaches 10-15 psi
  • Trapped dirt in the sand bed of the filter requires increased pumping pressure. Backwashing removes trapped dirt by reversing water through the filter

Backwashing - 10 easy steps:

1. Shut off heater and chlorinator. Allow heater to cool
2. Shut off pump
3. Arrange valves in backwash position
4. Change multiport valve to filter position
5. Turn on pump for approximately two minutes, until water in site glass clear
6. Shut off pump
7. Change multiport valve to filter position
8. Arrange valves in filter position
9. Replace dirty lint strainer with clean one
10. Start pump and send first 10 seconds of filtered water from backwashing to waste (known as 'downwashing')

Water Balance

Balanced water is germ-free. It also promotes comfort for swimmers and makes pool maintenance easy and economical.

Please contact the Health Unit regarding other water quality parameters.

Your pool's water balance depends on these factors:

  • Chlorine level (0.5 - 1.5 ppm Free Chlorine recommended)
  • pH-acid/base level (7.2 - 7.8 recommended)
  • Temperature (70 - 90 degrees F recommended)

Salt Water Pool Tips

  • Adjust control knob on salt system to meet demand

  • Maintain proper salt and stabilizer levels

  • Visually inspect pool to confirm proper filtration and chlorination

  • Keep pool recirculation system running constantly

  • Check salt level in pool every six months

  • Confirm salt unit producing chlorine (green light)

  • Clean cell to remove calcium deposits and maintain chlorine production

Safe Chemical Storage


  • Read and follow manufacturer directions
  • Use personal protective equipment when handling chemicals
  • Keep chemicals in a cool, dry, vented and locked place
  • Store chemicals off floor at reasonable height
  • Store dry chemicals above liquid ones
  • Clean up spills immediately


  • Store chemicals near flammable materials (paper, solvents, paint, etc.)

  • Mix chemicals

  • Leave chemical containers open

  • Use same scoop for different chemicals

Safe Pool Fencing

A pool-ready fence:

  • Prevents direct access to pool from house and other areas of yard
  • Meets municipal bylaws and height regulations
  • Self-closes and self-latches with inside latch
  • Features minimum 1.2m in height and gaps narrower than 10cm wide
  • Is free of items that would allow easy entry (trees, buildings, etc)
  • Has gate latch above children's reach and always locked when not in use

Safety Equipment Checklist

Are you prepared with these supplies?:

  • Safety equipment required by municipal by-laws
  • Throwing line with buoyant aid
  • Non-metal reaching pole
  • First-Aid kit
  • Telephone with emergency numbers posted
  • Pool 'supervisor' with First Aid, CPR, and water safety training
  • Properly-fitted personal flotation devices (PFDs) around the pool for toddlers and beginner swimmers
  • Buoy line at the shallow end, at least one foot before the deep end slope

Pool Rules


  •  Mark pool depts and unsafe diving areas clearly
  • Encourage feet-first entries
  • Ensure sufficient path of entry for slides and dives; slide feet first only
  • Restrict diving or sliding to one person at a time
