Also not sure of the need for the cap on the faucet. Wouldn't simply closing the 1/4-turn faucet accomplish the same thing as the little black cap?
Yes. The black plastic cap is merely a redundant device to secure the water line, on the off chance that little fingers of the grandkids might turn on the valve out of curiosity before Grandpa gets there to hook up the vinyl tube during the dumping process. The possibility is
very, very remote however.
In reality, I think it just gives the thing a more finished look. :B
