Product review (1 stars): Too Easily Triggered Shut by Washing Machine Opening Hot and/or Cold Water Valve
I chose this well made washing machine connector hose because of its built-in safety shot-off valve which does not require electricity. However, my experience has been that it is too easily triggered to shut off the water to the washing machine when the washing machine opens the hot and/or cold water valve. When that happens, one tends to look for a problem with the washing machine, such as a defective water mixing valve, because one tends to forget about the shut-off valve in these connector hoses.

I suspect the design has to be modified to tolerate a slightly higher water flow/initial pressure spike to prevent the valve from closing. My appliance repair person stated that he had to replace several of these hoses because they all shut off the water when the washing machine turned on
