This is from the Port Deposit Water plant. We actually had to freeze the 1" copper line in order to install a shutoff valve. So we are freezing the line directly off the 10" main (blue pipe) with 100PSI coming in on us and no way to shut down if it blows. Cool stuff!

 

 

This water heater is able to service a complete
3 bathroom home and deliver an endless supply of
hot water for an average of $100.00 less per year!!!
