Destructive Force of Ice

As most everyone knows, this winter has been hard on just about every corner of the country.  It’s been a very cold winter and the southeast has had its share of low temperatures.  For this reason, buildings that must be protected against fire sometimes have to use dry sprinkler systems.  Conventional systems that pressurize lines with water up to the sprinkler heads are impractical because the lines are usually routed through areas (such as attics) that are subject to falling below freezing.  As a result, the water in the lines can freeze and cause the lines to beak or burst.  When thawing occurs, water damage will also occur.  In order to prevent such damage, dry systems are employed.  That is, instead of filing the lines with water, the lines are pressurized with air.  Pressurized air serves to keep the main water valve closed until such time as a fire causes the sprinkler heads to open and relieve the pressure.  As the air pressure is relieved, the main water valve opens, water fills the lines, and exits through the open sprinkler heads to fight the fire.  However, there are times when water can get into the branch lines.  Water can enter when there is a loss of air pressure due to a leak in the system or when water is completely removed such as after a hydrostatic test.  The photos below show what happens to an iron pipe tee when water is frozen inside.  In one instance, the tee is broken in half whereas in the second instance, the tee is fractured on one end.  Note that both fittings came from the same job.  Ice typically expands between 9 and 12% by volume and as a result, places a tremendous amount of pressure on the fitting walls to cause failure.

Irrigation System Failure

Attention farmers and anyone else that uses long irrigation systems for crop growth. You risk damaging your equipment if you don’t maintain it on a regular basis.  Recently, we investigated the collapse of a system due to the accumulation of mud inside the main water distribution pipe.  A portion of the system is shown in the photograph below.


Instead of causing the truss supports to fail, the system came apart at the rubber boots between sections. When one section came apart, it dragged another section down. Two pipes were found especially blocked with mud and sediment debris.  The photos below show the blockages.




If your water source is a lake, river, or well, you are best advised to use some type of water filtration if you don’t want to risk this type of damage. The owner of this system was lucky in that his insurance carrier paid for the repairs.


Tankless Water Heater Explosion

While investigating the cause of a tankless water heater explosion, the extent of the damage reinforced the mechanics behind the explosive force. Tankless water heaters are devices that put a large amount of heat into flowing water in a very short period of time. But, when the water stops flowing and the heat doesn’t, there can be a tremendous release of destructive energy. It is well known that as water is  heated in an enclosure, not only does the temperature rise but, the pressure also rises as well. Pressure cookers are a good example of how water can become pressurized and if caution is not exercised by the user, can be come a deadly force. In addition, explosions involving conventional water heaters and boilers are not unheard of. As a result, temperature and  pressure valves have been required equipment on these items for a number of  years. However, tankless water heaters don’t have relief valves. Since the amount of water to be heated is less than one gallon, (when water is not flowing) it doen’t take long to cause the temperature and pressure  to reach explosive levels. The tankless unit currently under investigation contains two small reservoirs in which heating elements are immersed. The reservoirs appear to be constructed of  a hard, plastic-like material, the properties of which are unknown. The point at which rupture occurs is  dependant on the properties of the material because it is the materal that is  subjected to the rapidly increasing pressure.
