Hello Vinny S, Thank you for your question. Connecting portable dishwashers to kitchen faucets must be done with care. It is critically important to use the proper adapter size and gaskets. Not doing so could damage the spout permanently and cause leaks under the deck. We would advise checking with local plumbers or stores for adapters, as we do not make any. Best regards, Tanya
