    I enjoy using this product as it is just a water piping job and does not require batteries or power sources to work

    waggs water safety device

    Posted by Bolduc Plumbing Inc on Dec 23rd 2023

    I am a supporter of this product as it is designed to be piped in line with the hot water tank. my only dislike is that it is not able to be rebuilt. Because of this I only buy one at a time. I have lost inventory of these devices because the sensor was popped event though it was not flooded, it was set on a top shelf in a basement.

    Valve/customer service

    Posted by Liz Verteramo on Dec 27th 2021

    We had an older version of the wags valve, which did exactly what it was designed to do when the water heater under the kitchen sink died. I had some concerns and questions about the new one and Stephan addressed them all, going above and beyond by handling the return of the old valve personally to ensure we got a rebate for returning it. Could not have asked for a better experience! Thanks to Steve and the entire team for ensuring a smooth transaction, and thanks for the adorable mascot plush! Best marketing ever!

    Great little shutoff valve. By using these it sure has saved our customers a big and expensive problem when their water heaters start leaking. It is also easy to order and have received.

    WAGS water only valve

    Posted by Craig Barry on Nov 17th 2021

    Just installed two of these valves today. Very simple to install and both customers are happy with them. Also great when there is no power source near by. The customer service I received was second to none. Thank you!

    wags 7200-4w shutoff valve

    I have used this valve for more than 10 years. No fault found and purchased a brand new second valve for my new hot water tank. It is an excellent choice to save water and avoid property damage

    A great idea and support!

    This shut off valve is a great idea, well made and the Company stands behind them. We have one on each water heater. It provides a mechanical water shutoff and peace of mind.

    Great product. For the last 3 years I installed about 30-35 of them and no complaint whatsoever. Always great customer service and quick response.
    5 star!

    Best Invention Ever!

    Posted by Allison Kendrick on Jan 2nd 2020

    Like many other customers, I found this device installed on a hot water heater only after the water heater had broken. I purchased my house from a contractor who must have discovered this device in his 30 years in the construction business. I had four different plumbers come to evaluate what was wrong with my water heater, and each plumber was completely in awe of this thing once they figured out how it worked.
    I insisted that we buy a new one and install it on my replacement water heater, and now that I am writing this, I am going to buy some more to take with me in future moves. These things are an incredible way to save yourself from disaster. They are easy to install and ingenious.
