Preventing Frozen Water & Sewer Service Lines

February 25, 2019

If the water service line to your home has ever frozen or you have noticed a reduced water flow in your home during the winter, leave one tap running cold water day and night (stream should be the size of a pencil). This will help to prevent your lines from freezing.  Since frost sinks deeper into the ground when air temperatures rise after a period of extreme cold, you will need to keep the water running 24/7 until mid-April to avoid having the line freeze.  

The City encourages residents who have experienced frozen water service lines in the past to be pro-active by ensuring indoor lines are properly insulated, keeping a good snow cover over the ground above the service lines and installing a bleeder line system to maintain a flow in your water service. Flowing water is significantly less likely to freeze.

Your sewer line is also at risk of freezing.  If you notice the water in your sink or bathtub draining slower than usual, please run hot water down your drain to see if drain flow improves. If it does, continue to run hot water down your drain several times a day (filling a bathtub one quarter full of hot water and releasing it is a good method, this provides control of the released water) until the weather changes and the frost has come out of the ground, typically in mid-April.  If hot water does not improve the flow, contact a plumber.
