Will this aerator work with the Delta kitchen faucet RP21462? The original aerator is falling apart and leaking.

Asked by: Meg52
Hi, Meg52! Thank you for your question. The RP18508 is the correct aerator assembly for the RP21462 spout assembly. Best Regards, Rosanna

Is a substitue erator available which allows greater gpm?

Having been using this faucet for about 3 years and every single time I turn it on I cringe at ridiculously low flow. Is a higher gpm part available? If not how can I modify this part to be more usable?
Asked by: doug
Hi Doug, Thank you for your question and I apologize that you are having a low flow issue. Unfortunately, Delta Faucet model # RP18508WH has the highest flow rate allowed by legislation. It is possible that there is debris in your aerator which is slowing the flow rate. I recommend removing the aerator and soaking it overnight in a 50/50 solution of white vinegar and cold water to loosen any mineral deposits. Thanks. Jody
