tvoivozhd---you will have no problem at att---PVC has a design 
temperature limit of 140 degrees F.before it starts to deform under 
pressure.  It is fairly heat-conductive, so your frozen water would 
prevent the exterior from heat-damage unless you used a very 
high-temperasture and concentrated heat source like an acetylene torch.
