Reverse Osmosis Drinking Water in Oshawa

Tankless if budget allows. Tankless RO (Waterdrop G3, Frizzlife PD800, APEC Tankless) produces 400+ GPD on-demand, has 1:1–2:1 reject-to-permeate ratio (vs traditional tank's 3:1–4:1 — much less wasted water), no bulky pressurized tank under the sink, and digital TDS readouts. Tank RO is cheaper at $650–$1,400 vs tankless at $1,200–$2,400 installed. For a family of 4 with daily use, tankless pays back in saved water bill within 5–7 years.

Yes — RO membrane rejects 90–95% of fluoride. This is the practical option for Oshawa households (where city water is fluoridated at 0.6 mg/L) that prefer non-fluoridated drinking water. Standard activated carbon does NOT remove fluoride. The other option is activated alumina, which we use for fluoride-only specialty installs.

Yes — RO removes >95% of most PFAS chains. With Health Canada's August 2024 Objective of ≤30 ng/L for the sum of 25 specified PFAS, RO is the practical at-home answer for households concerned about Lake Ontario PFAS levels (currently low single-digit ng/L in raw lake water). Pair an NSF 401-certified post-carbon stage for additional emerging-contaminant capture.

Because RO removes minerals along with contaminants — including the calcium/magnesium that give water its mouthfeel. The fix is a remineralization cartridge (5th or 6th stage) that adds back calcium/magnesium/potassium for taste. Many tankless RO units include this stage by default. Cost premium $40–$120 over baseline.

Yes — RO reject water must discharge to a sanitary drain through a CAN/CSA-B64.10 air gap, per OBC 2024 Part 7 Section 7.6. A simple check valve alone is NOT compliant. The standard install routes the reject line to an air-gap fitting on the kitchen sink dishwasher tee or directly into the disposal. We handle this on every install.
