Spot on. Also it doesn't hurt to 'exercise' the valve when you are passing. Close a complete turn and open again. This helped earlier this year when I had to replace a 19-year-old CH pump head at the holiday home being observed by guests making pithy comments to me (and filming the process) between slurps of beer. .
