Reversing Valve Exploded

114 Views 2 Replies 3 Participants Last post by  markusolas
Had a heating and air conditioning contractor do some work on our central air system. Long story short the reversing valve literally exploded and sounded like a bomb going off. They had supposedly evacuated the system and I even overheard them talking that they thought the line my be restricted. Anyone ever hear of a line exploding like this before? Could that have been avoided?

Thank you in advance,

Never had one explode before. Can not imagine what went wrong that it would explode. When you evacuate, you create a vacuum equal to -14.7 psi. The valve is rated to 350 psi. One would have to work very hard to get on explode. Now if they had a torch on it, I can see under the right condition it could sound like an expiation.
Seems like you need new company and new equipment. :)))
