Yes, other pipes *could* be frozen, but if you had to wait till spring
to find em..... well, like I say, LOTS of people would be without
Keep the main water supply off, turn the heat on. This should thaw any
remaining freezing, and will allow the plumber to locate them.
Other than that, I would say find the lowest valve in your house, and
open it up, so that all the water in the system has a place to drain.
Also, open a faucet somewhere else in the house, to provide a vent for
the pipes. (Think of it like punching 2 holes in the top of a fruit
As far as not much water coming out of the faucets you have turned on,
it's hard to say. The good news is that I would bet you have at most 1
to 4 "burst" spots that will actually need to be repaired. Once one of
them freezes and bursts, there is a good chance that the pressure is
relieved on the rest of the system.
Get the heat going, keep the water off, call the plumber!
(And tell the husband to CHILL).
Best of luck,
