Rated 5 out of 5 by from Great force We bought an off brand with 1.5 GPM. Lacked pressure to really clean things. Getting a Delta product with 2.0 GPM (maybe higher?) was worth the extra money!!

Rated 5 out of 5 by from Delta Aerator Thanks for the quick and efficient service. The original Delta aerator literally fell apart. Now the faucet is as good as new again. Ready for many more years of service.

Rated 5 out of 5 by from Small Purchase Filled and shipped a very small, inexpensive order the same way many companies would do with a larger, more profitable purchase. Thanks so much for taking care of the little guy.

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
