Thank you for your question. The spout bonnet (Delta part #RP21464) would first need to be removed. At that point, the spout can then be detached from the retainer. Below is a link to the maintenance & installation guide for the 174-WHWF, which includes a parts breakdown.http://www.deltafaucet.com/customer...
