Frequently Asked Questions
What size filter unit do I need for a whole house water filtration system?
For most whole house water systems, a good choice is the 4.5" Big Blue 10" or 20" units installed on the main plumbing entry to a home. The larger size allows higher flow and longer life for sediment and carbon cartridges.
Do I need a professional to install a whole house filtration system with these components?
If you’re comfortable with plumbing (cutting pipe, installing shut-off valves, using Teflon tape), you can often install a small whole house filtration system yourself. For well water or more complex cottage water filtration systems, many homeowners prefer a licensed plumber or water treatment professional.
How often should I change the filters inside these units?
It depends on water quality and usage, but for a typical whole home water filtration system in Canada:
- Sediment cartridges: replacement intervals of 3, 6 or 12 months
- Carbon cartridges: replacement intervals of 6–12 months
Replace sooner if you notice a drop in water pressure or a return of odour/taste.
