Water lines 1.5" – 2"

High-capacity filtration
for large water lines.

If your building runs on a 1.5" or 2" water line, a standard whole-house filter will choke it. High-capacity systems treat all the water at the main without dropping your pressure.

Who needs one

Large homes with a main line above 1.5"
Restaurants — where water quality shows up in the coffee, the bread and the rice
Commercial buildings and multi-family properties
Any building where a standard system can't keep up with demand

For restaurants and commercial kitchens

Water shows up in everything you serve. Filtration at the main line changes four things at once:

Consistent ice and beverages. Chlorine and contaminants affect the taste of coffee, tea, cocktails and ice. Filtered water gives you the same pour every time.
No odours on the glassware. Chlorine and sulfur leave smells that cling to glasses. Taking them out at the main solves it everywhere at once.
Longer equipment life. Dishwashers, steamers and espresso machines last longer without scale and mineral buildup — and cost less to maintain.
Less limescale to clean. Faucets, sinks and fixtures stay clean with less work, which is labour you get back.

How to tell what size your water line is

Find the main line where it enters the building, usually near the meter or where the pipe comes out of the ground. Measure straight across the outside of the pipe, or wrap a piece of string around it once and measure the string.

Under 1.5" — a standard whole-house system will handle it. See whole-house systems →
1.5" to 2" — you need a high-capacity system.

Not sure? Send us a photo of the pipe at the meter and we'll tell you.

How the system works

Stage 1 — High-capacity layered filtration tank

A layered design distributes water evenly through the tank, which eliminates channeling and increases contact time with the media. The single tank combines KDF and catalytic carbon to reduce chlorine, contaminants and organic compounds, and improve taste and odour — without sacrificing water pressure.

Stage 2 — 5-micron sediment filtration

A final polishing stage that captures sand, silt, clay and any remaining sediment before the water enters the building.
