Q: I have a sewer odor coming up from my drains. What can I do about this?A: First, check the water traps for water. They are the P shaped traps in the drain lines beneath sinks, tubs, and showers. The standing water in the P-trap serves as a barrier against sewer gas and pests entering your home through the sink drain. Water in the P-trap may have evaporated due to infrequent use, or if the house is vacant. To fix this problem, pour a quart of water into each problematic drain; this amount of water is enough to fill the P-trap and provide a full water seal.Another source of odor is a build up of hair, dirt, and grime in your drains that can collect into a layer of slime that gives off an odor of rotten egg sulphur smell. If you are experiencing this problem, consult your plumbing professional on an appropriate drain cleaner for your home. Customers sometimes think the smell is coming from the water. An easy way to test to see if the odor is coming from the water is to fill a glass with water from the cold tap. Take the glass to another room and smell it. If there is no odor inside the glass, then you are experiencing a problem with your drains. Keep in mind that the City of Scottsdale only provides cold water to your home. If you are having issues with your hot water, contact a plumbing professional for advice.Q: I did the test, and my water tastes and smells funny. Is this water safe to drink?A: If you are experiencing a musty odor or taste in your water, you may be experiencing algae bloom. This natural phenomenon typically occurs between the months of August and October in lakes, rivers, and canals. The Central Arizona Project (CAP) Water Treatment Plant has added another treatment utilising granular activated carbon (GAC) that will help to eliminate the taste and smell associated with algae bloom. All City of Scottsdale water is treated and safe for drinking. Please review the City of Scottsdale Water Quality Report for additional information.City of Scottsdale Water Quality Report
