## Overview

The Water Block Excess Flow Water Shutoff Valve is a stainless steel, point-of-use device designed to automatically shut off water flow when it exceeds preset limits. Perfect for toilets, washing machines, dishwashers, and ice makers, it prevents costly water damage by detecting leaks or running water early. Easy to install and reset, this durable valve offers reliable protection and peace of mind for any modern home.

## Description

This is an effective "Point of Use" excess water flow automatic shutoff valve system. It is designed to prevent excess water from flowing when a device malfunctions. Examples would be a dishwasher, a refrigerator ice maker, a toilet, a washing machine, etc.. Any one of these can suddenly and randomly either fail to shut off when it is supposed to, or a line can break, leaking a lot of water and causing a lot of damage. Water Block can be preset at time of installation to limit the number of gallons that can run continuously before shutting off. For example: a toilet is flushed and continues to run. You have left for work, so it runs all day long and you end up with a large water bill. Water Block, preset just above the "normal" usage of the toilet, would shut off when the flow exceeds the shutoff point, and you save the big water bill. Or the ice maker tube breaks behind the refrigerator and you don't know it. Water runs and ruins the floor and whatever is below that floor. Water Block would shut the water off while it is still a mop-able mess, rather than a thousand dollar damaged floor, or more. Simple installation guide and reset unit included for quick return to usage of the water device.

    Requires excessive adaptation to standard appliance plumbing, product is physically very large
  

*by J***I on Reviewed in the United States 🇺🇸 on June 2, 2022*

It may have worked spectacularly, I don't know - I never installed it because it does not fit in-line with any standard interior household water plumbing. To be clear, you cannot simply remove your toilet or ice maker supply hose and place this device in-line with it directly out of the box, or even with standard adapters. To be fair, the description never said it would work that way but I think that's a reasonable expectation. It also did not make it clear that the device expects to be hooked up to a garden hose, literally. At least sell a kit of adapters to connect it to appliances one would typically buy this thing for - toilets, dishwashers, ice makers (it might fit a washing machine out of the box, but I think the flow limits might be too low).Setting the flow shut off volume was also not clear. A plastic "tool" is included to set the flow volume shut off (i.e., shuts off after X gallons flow through) but the instructions are long, tedious and very small type and it is not intuitively obvious how to do it. It was not clear to me after a few minutes of trying, and I hold multiple engineering degrees. I expect better, even if it's link to a YouTube video.When you open the box there are several (four IIRC) components. It is not clear whether all the components must be used in every application, or how they go together. I got the impression that maybe all of them aren't needed every time, but again, not clear. It was like they picked several things off the shelf that maybe weren't made to go together and just boxed them up. One of the parts is in its own box with instructions in the box. Another part, which did seem to be required to go with the one in the box, no box, no instructions. Then some plumbing components, and some loose instructions/paperwork in the shipping box. Frankly it was a hot mess.It is also physically very large. I suppose a dishwasher or ice make installation might not be so bad because it's behind an appliance. For a toilet, I'm not quite sure where you would mount this thing. Fully assembled it's probably 6-8 inches long.Most of these things become clear in retrospect when you look at the photos carefully, but not at first glance. The description and the instructions could be so much better. Amazon made return process easy so good for that.

    Peace of mind automatic water shut off
  

*by A***L on Reviewed in the United States 🇺🇸 on April 30, 2018*

We have a marginal well with hard water. Several times the toliet has remained running after being flushed and it has drained our water tank.  With this valve the water is automatically shut off once the preset amout of water goes through the valve. We have tested it several times and it shuts the flow of water. The company was very helpful with answering our questions. My husband easily installed it on the wall next to the toilet. Make sure it isinstalled vertical as it does not work if not level. Not sure how it will hold up long term. Our plan is to test it every 6 months or so to make sure it is still working.  Also to attach it to a toilet we needed to go to a plumbing supply store to get adapters for it to hook to the toilet line fittings.

    Works just as Advertised
  

*by R***S on Reviewed in the United States 🇺🇸 on September 5, 2020*

Using it just as it came from the box to protect a misting system to cool horses.  Tested it and it shut off at about 3 1/2 gallons of open flow.  Normal mister flow is too low to measure so it does not cut off during everyday use.  Could not do better if it were designed just for this application!
