How Reverse Osmosis Works
Reverse osmosis forces water through a semi-permeable membrane with pores small enough to block virtually all contaminants. A 5-stage RO system typically includes a sediment pre-filter, carbon pre-filter, RO membrane, carbon post-filter, and a storage tank — providing up to 99% reduction of dissolved solids.
We install under-sink systems with a dedicated drinking tap, so you always have access to clean RO water without affecting your regular tap. Optional remineralization filters add beneficial minerals back after filtration.
Pricing: basic 3-stage from $400–$600; 5-stage from $600–$900; with remineralization from $800–$1,200; annual filter service from $120.

Our RO Installation Process
Assess & Recommend
We assess your under-sink space, water pressure, and quality to select the right RO system for your home.
Install System
We install the multi-stage filter system, storage tank, and dedicated tap — typically in 2–3 hours.
First Flush & Test
We flush the system, test TDS (total dissolved solids) before and after to verify removal rates.
Filter Service Plan
We set you up on an annual filter service plan so your RO system performs optimally year-round.

What Coquitlam Homeowners Say
"The TDS reading dropped from 180 to 8 after the RO installation. The water is genuinely incredible. I haven't bought a water bottle in 6 months. The annual service plan is very convenient."
"We had a basic RO installed first and upgraded to the remineralization version a year later. Both installations were clean and professional. Highly recommend."
"I was paying $60/month for a water delivery service. RO system paid for itself in 8 months. The water tastes cleaner than the delivered water ever did."
Reverse Osmosis FAQs
What does reverse osmosis remove?
A quality 5-stage RO system removes chlorine, chloramines, fluoride, nitrates, arsenic, lead, copper, dissolved salts, most heavy metals, certain pharmaceuticals, and many other dissolved solids. The RO membrane itself achieves 95–99% rejection of total dissolved solids.
How much water does an RO system waste?
Traditional RO systems waste 3–4 litres for every litre of purified water produced. Modern high-efficiency systems (permeate pumps or tankless RO) reduce this to 1:1 or better. We stock and recommend high-efficiency models for Coquitlam homes.
How often do I need to change the filters?
Sediment and carbon pre-filters every 6–12 months. The RO membrane every 2–3 years depending on usage. Post-carbon filter annually. We offer annual service plans that handle all replacements on schedule.
What's the difference between RO and carbon filtration?
Carbon filters are excellent for removing chlorine, chemicals, and odours, but cannot remove dissolved minerals, heavy metals, fluoride, or nitrates. RO removes virtually all dissolved contaminants. For the purest drinking water, RO is the superior option; for whole-home taste improvement, carbon is more cost-effective.
Is RO water healthy to drink?
Yes. RO water is safe and healthy. Some people add a remineralization filter to restore trace minerals (calcium, magnesium) after RO filtration — this can improve taste and add beneficial minerals. We offer systems with remineralization built in.
