Advice Needed on Isolating Check Value All aspects of plumbing questions and answers, help, tips and information

Any advice on isolating this check value?

There is no handle as I would have expected.

Looks like an appliance isolator, rather than a check valve.

Anyway the lever has come off, so you need to either replace the lever or use some pliers to close the valve.
But a new valve will only cost a couple GPBs
