Hi. For some reason, the threaded bolt valve on the top of my csv1a must be stripped b/c it doesn't go up or down when trying to adjust it. So, I am ordering the Model CSV1A Spring Cage and hoping that fixes it so I don't have to undo the plumbing and such.

Question: with the small tank and the valve not working, my pump is turning on and off every 10 seconds when I run water. I don't want to burn out my pump. I'm not sure how long it will take if I order tonight, and ship it to Oregon. In the meantime, is this a situation where we just don't use water except in small doses, or is there something I can do with the valve in the meantime? Thank you.

The CSV1A is made to only be adjust a few times.  Once set it should never need to be adjusted again.  When you turn the bolt too many times or it gets wet from submergence or something, the grease on the bolt is not enough to keep it from galling to the nut underneath.  When the nut and bolt gall together, it spins out the plastic holding the nut underneath the spring cage.  Yes, a new spring cage will come with a new bolt as well.  Sorry for your problem.

In the meantime, if you can't turn the CSV down you could turn up the pressure switch.  Tighten the large adjustment screw in the pressure switch about 4 full turns to the right.  That will turn up the pressure switch by 10-12 PSI and may then be set higher than the CSV and will keep the pump from cycling on/off when using water.
