Thanks all for the suggestions. After a few days of deliberation, and since we are leaving in a couple days for our last camping trip of the season, my husband decided to take the easy route and replaced the o-ring and used plumbers tape around the point where the line for the handheld connects to the faucet. That has seemed to work so far with just running a bit of water through here at home but the real test will be while we are on our trip and using the shower. We will more than likely replace the entire faucet early next spring prior to our camping adventures next year. Thanks!
