1. Why does my hot water smell funny? The smell of rotten egg odor is due to the reaction of sulfates and micro-organisms in the water that create Hydrogen Sulfide (H2S). This does not mean a problem with your hot water heater but is due to the natural chemistry of the system. Sulfur-reducing bacteria that are naturally present in ground water use sulfur as an energy source to chemically change sulfates to produce H2S. The bacteria uses sulfur from decaying plants, rocks, or soil. They exist in environments that are oxygen-deficient (not enough oxygen) such as deep wells and plumbing systems. However, H2S can exist naturally in ground water as well. Now, the water heater has what is called an “anode rod”. This rod helps collect minerals that are in the water, keeping the minerals from attaching to the side wall and bottom of the tank. This rod is usually made of magnesium. The chemical reaction from the magnesium and the H2S can create the “rotten egg smell” that is harmless yet annoying. We usually can fix this issue by simply removing the magnesium rod and replacing it with a zinc rod. 
2. Why is the pressure in my lav faucet so low though the pressure in the rest of the house is fine? This is usually caused when debris that is “stuck” in the water supply system is loosened and ends up getting stuck in the aerator of the faucet. This aerator is a screen that helps give a steady flow out of the faucet. Simply remove the aerator by twisting it off, remove the debris and re-twist back on.
