Delta WFA-1000 Filter Installation
The Delta WFA-1000 filter housing mounts under the sink and connects to the cold supply via a saddle valve. The dedicated Delta filter faucet installs through the sink deck (uses existing hole or requires a 1-3/8" new hole). Installation time: 1--2 hours. Delta provides detailed installation instructions at deltafaucet.com and a customer support line (1-800-345-3358). Delta Touch2O faucet installation (for models with integrated filtration outlet) requires an additional battery pack installation under the sink for the capacitive touch function -- instructions included with each Touch2O model. Delta's Lifetime Limited Warranty covers all Delta faucets and filtration products.
