Freeze Alert Denver Front Range – Local Weather Centers Issue a Freeze Warning for Saturday October 10, 2009

Professionally having a lawn sprinkler winterization or lawn sprinkler blowout performed reduces the risk of damage to your Denver Lawn Irrigation System.

Denver’s Weather forecasters have predicted a rain/snow mix on Saturday into the night. Low temperatures are expected to reach mid to high twenties (25-28 Degrees Fahrenheit) everywhere across the Denver Metro Area from Golden through Greenwood Village all the way down to Lonetree, Colorado. Across the Denver Metro Area we have already experienced a light frost roughly a week ago. This frost expected Saturday would be a harder freeze which would be more damaging to Backflow Prevention Devices (BP). There are several ways to delay and hopefully avoid the onset of freeze damage to a Pressure Vacuum Breaker (PVB) or Reduced Pressure Assembly (RPA).

Allowing an irrigation system to continue watering the turf and garden areas requires the Backflow Prevention Device to be wrapped in Insulation. The Reduced Pressure Assembly (RPA) or Pressure Vacuum Breaker (PVB) is wrapped in Encapsulated Insulation and secured with Duct tape. Black Trash Bags are used to protect the insulation from water. The bags must also be secured by Duct Tape. Denver Area Commercial properties usually have the irrigation system running until the end of October and sometimes later. This is usually based on how low temperatures fall in Littleton, Englewood, Golden, Denver or the rest of the Denver Metro Area.

The most common method to avoid damage under short notice is to drain the Backflow Prevention Device. This only allows for expansion of the water through opening such as the Test Cocks. Backflow Prevention Devices (BP) should have the water to the irrigation system turned off. All Test Cocks/ Pet Cocks must be opened and left to a forty-five degree angle. Turning ball valves to a forty-five degree angle will also help reduce possible damage. Some Backflow Prevention Devices (BP) sometimes have a brass drain elbow or a brass drain coupler installed to help drain the pipe completely. It also has an added value of allowing water to drain over the winter if you have a defective Gate Valve.

Defective Gate Valves often are the true culprit of damage to Backflow Prevention Devices after they have been professionally winterized. The reason is because, Gate Valves contain a rubber gasket which over little time wears through or disentegrates and prevents seating of the valve. When the valve does not seat, water slowly and continuously leaks through your main shut-off to your Greenwood Village or Arvada lawn sprinkler system Backflow Prevention Device (BP). Defective Gate valves can be replaced with a ball valve by a company, such as A Better Garden Maintenance, LLC, which is licensed for Inside Tap and Backflow Devices.

If anyone would like to get a Denver Metro Commercial or Residential Property’s irrigation system winterized , please pay attention to the listing of the areas we will service dependent on the day. We still have openings on Mondays and Thursdays for the South Denver Metro area (Highlands Ranch, Littleton, Lakewood, Greenwood Village, etc.) and on Tuesdays and Thursdays for the North Denver area (Denver, Arvada, Thorton, Highlands Golden, Morrision, etc.) till the end of October.
