Re: Buying a home but the heat isn't on
Depends what you mean by cold temps.

Based on the description of the home the plumbing rework should be pretty straight forward.
You have the hot water tank ( which is likely turned off ) ---- the toilet --- all the water supply lines ( both hot and cold ) --- all the faucet cartridges and seals ---- the shutoff valves ---- P traps --- that would be damaged or stressed if they weren't drained
Assuming the water lines are copper ......
Copper pipes will take a fair amount of pressure from the standing water freezing before bursting ----- Copper is a soft and malleable material which stretches before tearing open . However , even though the frozen water is thawed and the pipe hadn't burst --- it has become weak from the streatching.
Also, when the standing water freezes and expands it's the points of restriction that create the problems. Areas like 90's and other soldered joints will become stressed from the increased expansion and contraction.
There may or may not be issues when the pipes are thawed and water flow is restored but you stand a good chance of annoying leaks later on.
Try this experiment at home ---- take a plastic bottle filled with water and put it into your freezer for a few days. You will see how the bottle distorts and may split open.
Hot water tank ----depending if it's a stand alone electric or fuel fired --- if allowed to freeze solid could damage the glass lining which will cause the tank to eventually rust and leak.
The plastic dip tube may crack or break inside.
Toilet ---- will crack when the water in the tank and bowl freeze solid
Faucets and shutoffs ---- seals and cartridges will leak when water is frozen solid
Personally I wouldn't bother with having a plumber do an air pressure test since this would mean having to disconnect and cap every pipe ---- which would reveal immediate problems but, may not reveal any future issues. Besides--- for the cost of this test you might put that toward the replacement.
All this should also be reflected in the reduction of the purchase price for the home.
