Thanks everyone for the great suggestions.
I'm using a Flojet 4405-143 35psi water pump. The manual for that pump
says "delivers smooth, steady water flow from 1 to 3 gpm without the
need for an accumulator tank". And "Special internal bypass feature
eliminates pulsating water and pressure switch chatter"
This is the pump here:

I do have a surge/accumulator tank, but a small one, like this
http://tinyurl.com/2lbd92
That accumulator was installed just before the hot water tank, in an
attempt stop the pressure-release valve on the heater from dripping
periodically. (That didn't work either).
So the surge/accumulator is only on the hot-water circuit. That may be
my problem. I'll have to experiment. Also, that accumulator tank is
about 2 years old, I may have to re-pressure it.
I may also insert a valve or smaller-diameter hose in the cold water
circuit, before the shower. That may help too?? Is this a good option?
Thanks again for the suggestions.
