Through a comedy of errors the connectors for the tubing beneath my faucet were thrown away. These are custom connectors. I managed to pick up new connectors for the faucet (hot and cold to spout) but was not able to get a connector to the sprayer. As a result, if I turn on the water valves, water will shoot out of the hole where the sprayer used to be connected.
Is there a sensible way to temporarily and reversably plug the sprayer inlet piping (pictured) so I can use my faucet and dishwasher until the new sprayer assembly arrives on Tuesday? Recall this fitting is not threaded and so the patch would have to fit inside or wrap around the outside.
