I dont know what to do. This faucet was installed by a builder in my condo. I really liked it at first and it was a center piece in my kitchen. However I started noticing random switching to spray mode 1 year in. Its been 2 years now and I can't turn the faucet on without it loudly flipping to spray mode. Trying to switch it back grants 3-4 seconds of normal flow before it jumps back to spray. I tried contacting support multiple times, however their hours are regular work hours and after waiting for over 2 hours several times I had to drop out. Could someone please share a part number and a guide on replacement. I would greatly appreciate any help.
