After arriving to the home, the homeowner made me aware of a leak coming from her R.O System Faucet. She just replaced the filters to her system last week, however a leak started to occur after the installation. Three lines lead to the base of the faucet which are the filtered water line, air gap line, and the line for drainage. The homeowner had used the shutoff for the faucet to isolate this issue. Once turning the water on to the faucet, water began to leak out the side of the faucet. I checked the drain line and removed build up from the line, however this did not resolve the issue. After giving estimates with upfront pricing to replace the faucet from Whirlpool, the homeowner would like these estimates emailed to discuss with her husband tonight, they would like a follow up call from the office tomorrow. I have waived the dispatch fee.
