This 2-in-1 faucet and shower flow gauge measuring bag is a must-have for home and commercial use. The measuring bag is designed with a clear scale, which makes it easy to read and measure the flow of water. This measuring bag is perfect for measuring the flow of water in faucets, showers, and other water pipes. Your faucet fixtures and showers say that send out a certain amount of water, but is that really accurate? Are you wasting water (and money) without even knowing it due to a faulty flow controller or an old aerator? With our flow gauge measuring bag, you can quickly and easily find out for sure. Knowing how much water you're using is the first step in water conservation. By finding out how much water your fixtures use, you can make smart decisions about upgrades.
