NOTE:

It is recommended to check the O-ring before connecting the hose to your heater, and to replace the O-ring if it is cracked or damaged.

It is also recommended to check for any leaks after installation. A very quick and easy way to do this is to mix some water with a few drops of soap, and spray or pour it on the installed fitting to see if any bubbles come up.
