I have a new DELTA Kitchen Faucet num. 989-DST, my problem is that I get half gallon per minute and manual specs. Is 2 gallons / min.
I don't know where is the problem,
I already disconnect lines and use them without faucet, I really have a very good pressure from outside.

If I try to use it without final cap, I get same result ---> half gallon / min.

Can you help me to give me an advice about how can I increase flow ?

Thanks in advance for your help.

Remove the Aerator try the faucet and see how is the flow if good clean and install the Aerator see the image below, Thanks.

Probably a clogged cartridge. Product Documentation : Customer Support : Delta Faucet

Close both hot and cold angle valves under the sink, Remove the cartridge open the angle valves for a second to flush out debris out of the faucet have a towel on the faucet to catch the water, clean the cartridge and assemble, see if it works if not you have to return the faucet back to the store for warranty, open the link below, Thanks.
