When a pipe can implode or explode

Air traps and stand traps are the two primary examples. They give that water somewhere to go so that it, in theory, won't damage or destroy the pipes in a home. They're sometimes called air vents or vacuum relief valves, and they work to let air into the line to keep these dangerous vacuums from occurring. This is just as problematic as an exploding pipe, and air traps are meant to deal with the problem. 

The Water Hammer Phenomenon - 

Basically, a water hammer refers to a loud bang or hammering sound that occurs when a valve becomes closed at the end of a pipeline system.

 A water hammer is a very, very common plumbing problem that can be dealt with early enough to prevent a major expense. Many people hear this bang start to happen and think nothing of it; it may take a while before serious damage takes place, however it is recommended that it should be taken care off straight away as there is no way of telling of when a pipe can implode or explode. Building inspectors know what to look for, and homeowners should have their pipes examined periodically to make sure that no majorly catastrophic problems are in the "pipeline," as it were. 

Air Traps And Imploding Pipes - 

When a valve is closed in the plumbing system, water might keep trying to flow. In these instances, the telltale water hammer noise will happen which generally provides warning of an impending problem. Yet many homeowners know absolutely nothing about them. 

Stand Traps Prevent Water Hammer - 

A few different ways of preventing water hammer have been devised through the years. Stand traps - which are open on 3/4-2" Plastic PVC MF Single Union Ball Valve Manufacturers the top - work as cushions to soften the impact of a wave of moving water. Educate yourself about water hammers now to avoid a very expensive lesson later on. Such circumstances can cause extensive damage and generally are associated with extensive repair bills. This creates a vacuum which can then cause a pipe to implode or collapse in on itself. In such instances, a loud bang will alert you that a pressure wave has taken place. Stand traps are meant to prevent exploding pipes caused by high pressure water with nowhere to go - one of the most common causes of water hammer.
