Product review (3 stars): Connect to the cold water supply rather than the hot water supply
Edited review:  The two hose adapter is flimsy and may burst or split and I substituted other "Y" adapters.  Although I, at first, thought that the hose should be connected to the hot water supply, this was incorrect and other reviewers corrected my mistaken thinking.  I will leave the
steam-dryer connected to the hot water supply for now and might reconnect it to the cold water supply later.  Thanks to those who helped me understand the connections.
