A 5065A buyer is looking for the best short term stability he can find (nominal 1.5X10-13th at 100 Sec) Keeping on frequency is easy via GPS comparisons. A Cesium buyer want NIST traceable accuracy "out of the box" and never (practically) having to adjust the frequency.

The good news is that if you have to remove the bowl, or the drain cock breaks, then you might as well, while the filter is apart, get the re-build kit and replace all of the bits and pieces that come in the kit. This, too, is easy to do and requires no special tools other than screwdrivers and a Cresent wrench.
