Denver Sprinkler Winterization – Get it done the right way
October is here and it is now time in the Denver area to get scheduled for a sprinkler winterization. Generally, it is best to wait until towards the end of October in order to get as much water into your landscape for the winter. But you need to call now to ensure an appointment to get your sprinkler system blown out. As soon as temperatures drop below 28 degrees there is a high risk of immediate damage to expensive components of your irrigation system.
The initial concern mitigated by winterizing your sprinkler system is protection of the AVB, PVB, or RPA. These are different forms of back flow prevention devices used to protect your homes drinking water. Most homes in the Denver area have a PVB or Pressure Vacuum Breaker. This device is above ground, made of brass and should be connected by copper pipe & fittings to both the water supply & the sprinkler manifold/mainline. The sudden decline of temperature greatly affects the metal which may burst if not properly winterized due to the water expanding into ice while still in the components. Even a basic repair to these components is going to be at least $100.00 is the system is not winterized. If the system is still active and a break occurs at the water supply, there may even be flooding in the house.
When the ground begins to freeze there is a high likelihood of water in the pipes under the ground freezing or the electric control valves freezing & breaking. This will be more likely to occur in the middle of winter as the temperatures drop into the negative digits. A single crack in the manifold can cause the whole manifold to need to be replaced. The labor & parts are very expensive to replace when freeze damage has caused needed repairs. The best solution to prevent damage to your Denver sprinkler system is to get it properly winterized.
Proper winterization is done with a compressor which can evacuate all the water in the lines. A compressor which is rated at 100-185 CFM (cubic feet per minute) is required to properly blow out a sprinkler system. If you have a larger mainline, such as commercial properties generally have, then a larger compressor is needed. The amount or volume of air going through the system, rated as CFM, is much different than pressure. The pressure will drop to almost nothing if there is not enough volume of air to get all the sprinkler heads fully popped up. Full extension of the heads is generally necessary to get all the water out of each zone of your sprinkler system. Make sure the company does sprinkler blowouts correctly and uses a large tow behind compressor.
