Rated 5 out of 5 by from Just what I wanted This faucet was bought to replace an old leaky model of another brand. I like the high arc of the spout and the lever handles. It is easy to turn on and off. The spout swivels smoothly and the sprayer works great. This is an easy to install unit.

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
