I don't agree.  40-on, 60-off pressure switches are commonly used in 
many houses, including mine.  All the appliances work just fine.  The 
variation in pressure as the system cycles is not usually 
noticeable.    70psi is a little above normal, but this is usually 
just a matter of adjusting the cut-off point on the control 
switch.  Actually, the whole switch is not that expensive, so if it's 
rusty and crusty from years of service, it's easier to replace than adjust.
