YoLinkX3 Version Smart Water Leak Protection Kit: X3 Valve Controller, Bulldog, (4) Leak Sensors & Hub

YoLinkX3 Version Smart Water Leak Protection Kit: X3 Valve Controller, Bulldog, (4) Leak Sensors & Hub

Q: I have read some reviews that say the Bulldog Valve Robot is not strong enough; is this true?

The motor in the Bulldog is quite strong, but the valve must be in good working order. It should move smoothly requiring no force to close, otherwise & particularly combined with a poor installation, can prevent the Bulldog from operating properly.

Q: I have read some reviews that say the brackets come loose or it moves during operation. Is this a design problem?

The Bulldog design is exceptionally good. The brackets should be tightened to the valve, not to the pipe, and not tightened to the round end of the valve, else it will slip. We have updated our user documentation to make this very clear.

Q: What tools and what skills or expertise do I need to install the Bulldog?

You will need a medium Phillips screwdriver. The valve controller for it will require a couple screws in the wall - that may require a drill. If you know how to use a screwdriver, and are willing to read the installation manual, you'll be fine!

Q: So, what do you mean by "poor installation"? :-)

The Bulldog is a bolt-on product, it does have a couple parts that have to be properly assembled and aligned to the ball valve. Most support requests we get are from very simple things like a loose screw, or the instructions were not followed.

Q: Should I get the Bulldog or a motorized valve?

A motorized valve will always be superior to a bolt-on valve operator/manipulator, even one as nice as the Bulldog. We are here for you if you have any questions not answered by our information here.
