Rated 5 out of 5 by from GREAT FEATURES AND SUPER EASY INSTALLATION We are so happy that we chose a Delta Faucet over all other faucets. We had a plumber install it and in his opinion, it is the best faucet on the market! We love the ease of use and the stainless steel appearance.

What kind of adapter would I need to attach a portable dishwasher hose? it's to small for the tip and when I unscrew it it's too big. can't seem to find the right size. Any help is appreciated

Asked by: theopholismmviii
Hello, Theopholismmviii! Thank you for your question. The Delta Foundations Kitchen 21988LF-SS faucet has an aerator with a thread size of 55/64"-27. You will need to talk to your local retailer or wholesaler about getting an adapter that fits your portable dishwasher to also fit the faucet thread size. We do not manufacture any adapters for attaching dishwashers or filters. Best regards, Tanya

Why does it take a few seconds for the water to stop? The faucet is new.

Asked by: GiGi
Hi, GiGi! Thank you for your question. With our high arc faucets, the water does take a few seconds to drain out the excess water after shutting the water off. If the faucet leaks continuously after shutting off your water, please contact our customer service line so that we may help you further. Best Regards, Rosanna
