Hi HumbleOpinion,
Thank you for your review! I do apologize you are not satisfied with your Delta model 16935-SSSD-DST, but I will be happy to help further.
Leaking is caused by debris stuck in the faucet or cartridge, we would recommend flushing the faucet. I have included below the flushing instructions.
To flush the unit, we recommend the following:
Check the supply lines:
Turn the supply off to both the hot and cold-water lines.
Once off, turn the handle on the faucet to the on position and leave it there to bleed the lines of any excess water.
Next, disconnect the hot water supply line and place it inside a bucket.
Once the line is securely positioned into the bucket, turn on the cold-water supply, then do this with the hot waterside.
Once the flush has been done, please reconnect both water lines. Lastly, insert a small screwdriver into the slot in the button and remove it. Loosen the set screw inside the handle. Remove handle. Remove cap by rotating counterclockwise.
Bonnet may be stiff due to O-ring, but should rotate by hand. Remove the bonnet
nut by rotating counterclockwise with a wrench. Remove the cartridge by
pulling it directly back on the stem. Take a soft cloth and wipe the puck located behind the cartridge, let the cartridge soak in a 50/50 mixture of white vinegar and water for about 10 minutes before reassembling. This should fix the leak you are having, but if you find the issue remains, the cartridge would need to be replaced.
