Review on GRIDMANN Commercial NSF Stainless Steel Sink With Faucet & Side Splashes - Wall Mount Hand Washing Basin by Steven Barbon

I have has this sink (professionally installed) for 4 months and probably turned the water on 3x/day.Now, 4 months later, the hot water handle no longer works. You can turn and turn and all you get is a slow stream of water. Cold water handle works perfect.Water pressure in adjoining room is perfect. Water in sink 6 feet away has perfect pressure. Not really sure what happened here, as the sink worked fine for the first 2 weeks.
