Thank you for your question. If the 21902LF faucet leaks, we recommend to flush the valve for any debris that might be causing the leak. We also recommend to replace the seal kit, as well. To determine the repair kit for your faucet, you will want to find the supplier code on the back of the faucet. If your supplier code is 413763, we recommend to use RP47422. If your supplier code is 449401, you will want to use RP78201 and RP4993 repair parts.
