While the facet pump is excellent if it used frequently, it can and will
fail if it is used infrequently. It appears that the shuttle will rust if
the pump sits idle for extended periods. The saving point is that it will
generally fail in the startup mode rather than in use.

I have had this happen in the past on my test stand once or twice each year
until I switched the stand to a motor driven pump. In the past twenty years
I have had two Mazda trucks which had the same Facet pumps installed and
between the two have given the full twenty years service with no hint of a
problem but the trucks are used daily. Dave J.
