Firstly, I was not injured ! Got a little wet and confirmed that my heart is in good condition.

While preparing for our 1st trip of the year, I sanitized the freshwater tank this morning. All OK. I wanted to make sure the hot tank plug was properly seated, as I left it loose for the winter - but apparently not loose enough. I was smart enough to disconnect the primary battery cutoff, BUT, forgot to depressurize the hot water tank. I wanted to remove the plug, then secure it back. Sure enough, when I went to loosen the plug,.... BAMMM !

As soon as it happened I knew what I did or did not do; relieve the pressure first. As I said, luckily no injures although a little wet and now a little smarter. Having said all that, did I, or could I have done any damage to the hot water system or the overall water system by the rapid depressurization ???
