Flow-Rate Based Water Leak Detectors

Point-Of- Use Automatic Shutoff Valve: WaterBlock

Overview - Click on product listing at bottom of this page for further information

WaterBlock excess water-flow shut-off valves help prevent water damage by shutting off the water to an appliance when the volume reaches a preset level. Install them in the water lines that feed your plumbing fixtures or appliances, for example drinking fountains, ice makers, or dishwashers. WaterBlock measures the amount of water flowing through the water line; if a continuous flow of water exceeds your preset volume, WaterBlock will then shut off the water to that fixture. The water then remains turned off until you reset WaterBlock.

If a continuous flow of water ends before triggering your preset maximum volume level, WaterBlock automatically resets its measurement back to zero in preparation for the next water flow cycle, allowing for continuous water flow up to the limit that you set.

For instance, assume you set 5 gallons as your continuous flow limit. When the water runs, WaterBlock would count the volume of continuous water flow. The water would continue to run as long as it did not exceed 5 gallons of continuous flow. However, as soon it reached 5 gallons continuously, WaterBlock would shut off the water. If the water flow stopped before reaching 5 gallons, WaterBlock would reset its measurement back to zero and begin counting again the next time that water starts running, thus continuing the cycle.

Features

• WaterBlock does not require electric power. All it needs to operate is water flowing through it.
• It can be used in both cold and hot water (up to 158 degrees Fahrenheit)
• WaterBlock is a Point of Use water shutoff system, to be used in conjunction with fixtures like ice makers, toilets, water coolers, coffee makers, or dishwashers.
• Note: WaterBlock is not intended to function as a whole house shutoff valve. Instead, you install it in the water line feeding a particular fixture or appliance. WaterBlock must be mounted vertically, with water flow either up or down. For whole-house shutoff, see YdroStop, below.

Example:

Lets say you install WaterBlock into the water line that feeds a coffee maker, setting its limit to 1 gallon of continuous water flow, since this hypothetical coffee maker uses 2 quarts of water per brewing cycle. Normally, the coffee pot draws its 2 quarts of water and then turns the water off. As the water flows, WaterBlock counts its volume; when it stops at 2 quarts, WaterBlock resets its count back to zero.

However, if the coffeemaker malfunctions and fails to turn off the water, WaterBlock will automatically turn it off for you once the continuous flow of a cycle reaches 1 gallon. It will then keep the water turned off until you reset it. By shutting off the water, WaterBlock helps to prevent or minimize what could have been extensive water damage if the malfunctioning coffeemaker had allowed the water to stay running, soaking the surrounding kitchen area.

Water Block comes in 2 sizes:

• Low volume: Model WB-13 can accommodate continuous volume between 1 - 13 gallons
• High volume: Model WB-26 can accommodate continuous volume between 2 - 26 gallons
