Smart Valve™ vs. Low-Flow Fixtures: Which Saves More on a Commercial Property?

Low-flow fixtures are the most common water efficiency recommendation for commercial buildings. Smart Valve™ is different — it works at the meter level, not the fixture level. Here's a direct comparison of both approaches.

How Low-Flow Fixtures Work

Low-flow fixtures (toilets, faucets, showerheads) reduce water consumption by limiting the volume of water delivered per use. A low-flow toilet uses 1.28 gpf vs. 3.5–7 gpf for older models. The savings are real — but they require replacing every qualifying fixture in the building. For a 200-room hotel or a 300-unit apartment building, that's a capital-intensive, disruptive, multi-month process. Tenants notice. Operations are affected. Contractors are needed on every floor.

How Smart Valve™ Works

Smart Valve™ installs on the main water supply line — one unit per building. It removes entrained air from the water system before that air passes through the meter. Because water meters count air as water volume, removing the air reduces the meter reading by 15%–35%. No fixtures are replaced. No tenants are notified. No contractors work room by room. The installation takes 4 hours on the main supply line.

The Additive Case

Low-flow fixtures and Smart Valve™ are not competing solutions — they address different parts of the water bill. Low-flow fixtures reduce actual water consumption at the fixture level. Smart Valve™ reduces metered air billed as water at the supply line level. A building with both installed will see additive savings from both mechanisms simultaneously.

For properties with existing low-flow fixtures, Smart Valve™ captures savings that fixture replacement cannot — because fixture replacement does nothing to reduce the entrained air that the meter is already counting as water.
