FAQs
How does Kingston’s municipal water quality affect the choice of an under-sink filter?
Kingston’s tap water is generally safe and meets provincial standards, but it can still contain trace levels of chlorine, sediments, lead from older plumbing, and seasonal taste or odour issues from Lake Ontario. An under–sink filter—typically a dual-stage carbon block or a reverse-osmosis (RO) system—removes these residual contaminants, resulting in better taste, odour, and added protection for vulnerable users such as children or immunocompromised individuals.
What types of under-sink systems are available and which is best for my home?
The two most common options in Kingston are: (1) Carbon block or carbon/ceramic combo filters that reduce chlorine, particulates, lead, and volatile organic compounds; and (2) Reverse-osmosis (RO) systems that add a semipermeable membrane to remove dissolved salts, fluoride, nitrates, and many pharmaceuticals. Carbon systems are compact, require no drain connection, and preserve beneficial minerals. RO units provide the highest level of purification but need more space, a dedicated faucet, and periodic membrane replacement. The best system depends on your space, water-quality goals, and budget.
Is professional installation necessary, or can I install the filter myself?
Many DIY-friendly kits include push-fit fittings and colour-coded tubing, allowing a competent homeowner with basic tools to complete installation in 1–2 hours. However, hiring a licensed Kingston plumber ensures code-compliant connections, prevents leaks, and maintains warranty coverage. Professional installation is recommended for RO systems (because they require a drain saddle and possibly a hole in the countertop) and for homes with older copper or galvanized pipes that may need special adapters.
How often do I need to replace the filter cartridges?
For most carbon under-sink units, the primary cartridge should be replaced every 6–12 months or after filtering about 2,000 litres—whichever comes first. In high-sediment areas or large households, you may notice reduced flow sooner. RO systems usually have a three-stage schedule: sediment and carbon pre-filters every 6-12 months, the RO membrane every 2–3 years, and the post-carbon polishing filter annually. Always follow the manufacturer’s guidelines and mark replacement dates on a calendar to protect water quality and system longevity.
What ongoing maintenance is required besides cartridge changes?
Maintenance is minimal: (1) Inspect all fittings and tubing for leaks every few months; (2) Sanitise the system annually—especially RO tanks—using food-grade sanitiser; (3) Check water pressure (ideally 40–80 psi) to avoid damaging the membrane; and (4) Replace O-rings and lubricate them with silicone grease when they show wear. Keeping a log of service dates helps you stay on schedule and preserves any extended warranties.
How much do under-sink filtration systems cost in Kingston, including operation?
A quality carbon block system ranges from $150 to $350 for the unit and faucet, plus $100–$200 for professional installation. Annual cartridge costs average $50–$80. RO systems cost $300–$700 for a 4–5 stage setup, $150–$300 to install, and about $120–$180 per year for replacement filters and membrane amortisation. Even at the high end, purified drinking water typically works out to less than 10 cents per litre—far cheaper and greener than bottled water.
