Hello Rod13,
We're sorry you are having trouble with your Ladera bathroom faucet. The aerator can be removed using a coin; no special tool is required. The coin is inserted in the aerator slot to use as leverage and turn counterclockwise. If the faucet is experiencing low water flow, it could be the inlet adapters. Sometimes, these can get loose debris lodged in them, reducing the water flow. We want to go through some troubleshooting steps to determine if this is the cause of your reduced water flow or if it could be the cartridges. We have included a few steps below to check the inlet adapters.
Please turn off the water supply to the faucet before proceeding with these steps.
Step 1: Once the faucet's water supply is turned off, remove both cold/hot water supply line hoses from the faucet's inlet lines.
Step 2: Remove and check the inlet adapter parts #970-074 for any debris or particles that may have gotten stuck inside.
Step 3: With a soft bristle brush, gently brush away any debris or run it under a stream of water and reconnect the adapters to the inlet lines, then connect your water supply lines and test.
Please call us at 1-800-732-8238 if these steps don't help, and we'll be happy to troubleshoot with you further to resolve this as soon as possible.
Thanks,
Pfister
