This Cliche means:
Test the Waters: To try something out. This expression, which alludes either to testing the purity of water in a well or to putting one’s hand or foot into water to test its temperature, dates from the late 1800s. Diana Ramsay used it in a Little Murder Music (1970), “’If you’re attempting to establish a motive.....’ – ‘I’m just testing the water,’ Meredith said.”
I sincerely hope you enjoy this caches.
