ABSTRACT:
The present invention is a leak prevention system that monitors and detects loosening of a valve. The leak prevention system includes a biasing member, a tightening member, and a pulling member. The biasing member has a first end and a second end, the first end being in communication with the tightening assembly, while the second end being in communication with the pulling assembly. The tightening assembly is carried by the valve, is adapted to tighten the packing nut should packing from the valve loosen. The pulling assembly is adapted to pull the tightening assembly via the biasing member after packing wears away, such that the wearing away loosens the tightening assembly and the constant force of the biasing member, supported by the pulling assembly, causes the tightening assembly to move. After packing has worn away, a visual indication can indicate to an operator that the valve may soon leak.
