   I recently used soap and compressed air to find the leak in my old water   
   heater and check the connections on the new one. Then I tested the household   
   plumbing for leaks by watching the pressure with the meter shutoff valve   
   closed.   
      
   Soap is fine at room temperature but won't help on the hot reactor, where   
   metal moves as it expands and heat creeping out into the plumbing will   
   complicate a leakdown check.
