I tell you what I love Australia, those Mad Max Movies were the BEST! I can’t believe that they have that much of gasoline shortage, What a minute! Could it be that everyone in Australia tests there T&P valve everyday, causing a severe electrical shortage thus incuring a fossil fuel shortage!
Seriously, the T&P valve is one of the most important safety valves on a plumbing system. Testing it should be done by a licensed proffessional. Yes they should be teated according to manufactors specifications. Never ever plug this item when it leaks call a professional.
