1. Open the package and check if the stainless steel sink and its drainage components are correct and complete.
2. Use the cutout template included in the package to cutout a hole in the countertop. Check if the sound silencing pad is peeling off. If so, stick it again.
3. Check if the faucet has any cracks or if the sealing rings on the kitchen faucet valve has any dislocation, damage or are missing. This is to avoid leakage when the faucet is installed.
