I secured it with a hose clamp. I've lived in my apartment for over 10 years, where the faucet was original to the s building, and it handled my portable machine just fine. An amazing amount of lint collects and that gets really expensive. Since it's a co-op, could you ask permission of the board to install a separate, appropriate, faucet on one side of the kitchen sink where many people have a filtered water faucet or a hot water faucet?
The supply hose needs to be connected to the cold hose connection.
