Sometimes I have low pressure, what causes this?

The first thing I would ask as a customer is, "Do I have low pressure throughout my home?" If the answer is no, I would check to see if I have a clogged filter screen on that faucet, which can be unscrewed & cleaned. Another cause can be a water leak in the area, affecting the pressure in your home and your neighbors'. Finally, severe drought conditions cause people to use a tremendous amount of water, especially the watering of lawns. There is an ordinance in effect during dry months to remedy this situation, but we need everyone's help in educating neighbors to ordinance.
