Thank you for your question. The 9113T-DST sprayer assembly should have a 1.8 gpm flow rate. If you are getting 0.5 gpm, we recommend to clean the sprayer by soaking this in a solution of 50% white vinegar and 50% water solution. You may soak for an hour or even overnight to clean. If this does not fix the issue, please contact our Delta Customer Service line at (800)345-3358. We are available Monday-Friday, 7am-7pm, CST and Saturday, 8am-5pm, CST. You may also email at firstname.lastname@example.org.
