With DrizzleX, anytime before fixture set - because nothing goes into the walls. Traditional submetering has to enter the drawings early; DrizzleX micrometers hand-tighten onto finished fixtures at trim-out, so there's no rough-in dependency and no deadline buried in the construction schedule.

It doesn't have to - and that's the point. DrizzleX adds no mechanical-room infrastructure, meter banks, or riser changes. Micrometers install on each fixture as part of standard trim-out, sized in advance to the project's pipe specs.

Yes - during construction the plumbing is exposed and crews are already on site, so installation is at its easiest and cheapest. Installing early also covers the finishing phase itself: construction damage - a tile dropped on an exposed pipe, a fitting knocked loose - shows up as a flow anomaly before move-in, not as a surprise after. And in California, submetering new multifamily buildings isn’t just the cheaper path - it’s required by law.

It varies - the developer, the mechanical engineer, or the GC can all carry it. With DrizzleX the spec is light: share the fixture schedule and pipe sizes, and devices arrive sized to match, ready for whoever sets fixtures.

Yes - the same DrizzleX measurement does both. From the first move-in, every unit's actual gallons are billing-ready, and every fixture is monitored for leaks and overuse, minute by minute.

No - DrizzleX micrometers report over their own dedicated network. Nothing added to the low-voltage scope, nothing on the building network, nothing for residents to set up.
