Hello, I recently had a bathroom sink faucet installed from Home Depot. Glacier Bay Constructor 4 in. Centerset 2-Handle Low-Arc Bathroom Faucet Model # 7032E-B6101. Its WaterSense certified so I think that could explain a very small stream of water. Except that instead of releasing 1.5 gal/min as advertised it releases 1.25 quart/min. But beyond that there is little water pressure and it takes almost 2 minutes for warm water to come out. Once it comes out it never turns hot. What could be the problem? Is this a problem with the installation or something else? Thank you very much for any help.
