If pipes are frozen no water can flow, so water meter shouldn't be registering anything.
But if pipes are frozen it's a good idea to turn the water off at the inlet. That way you have a chance to discover and leaks and damages when the pipes thaw w/o getting the whole place flooded.
It could be a number of reasons. Has any of your pipes frozen? Are all of the water valves turned on? Did you pay your water bill?
yes
choir members in your pipes
Usually you should if your pipes are at risk of freezing. (i.e. you live in a cooler climate and the house has no heat.) The reason for this is that even though your pipes are drained, there is still water in the low spots, which when frozen will expand causing pressure build up. If the air has no where to go it could cause a crack and probably some water damage when ever you do turn on the water. }th0rn{
If you close all water shutoffs or all water faucets and the water flow indicator on your water meter is moving, then you might have a burst pipe. Also, if your pipes are frozen, no water is coming out of any faucets, and your water flow indicator on your water meter is moving, then you probably have a burst pipe. Hope this helps.
replace the fill valve
depends on what type of piping you are talking about. Are you talking about frozen pipes bursting or High temps??
You should always check for pipes by hand, many pipes are PVC and will not show up on a metal detector.
There is no such unit of measurement as the "pipe".
Pressure has nothing to do with pipes freezing. It is just exposure to cold.
water expands when frozen.
is it condensation possibly.
