As fall approaches in Northern Colorado and the weather gets colder, you run the risk of freezing water causing damage to your sprinkler system. Don't forget to winterize sprinkler systems. Here on the plains in Greeley, CO sprinkler system maintenance is an important part of lawn care, both to protect your sprinkler and keep your lawn healthy in the warmer months.
And we offer blowouts at a very reasonable price - we start at only $40 and most people fit into that price range; the price goes up depending on the size of the system.
Water left standing in your sprinkler system will expand and crack the pipes or rupture the pipe walls. If water freezes in the backflow assembly, the internal components will become damaged, possibly cracking as well.
Unfortunately, you may not be aware that your pipes have frozen... until you turn on your sprinkler system in the spring. It's a nasty surprise and a major sprinkler system repair.
You can easily avoid the headaches and costs of a broken sprinkler system by proper sprinkler system winterization before the really cold weather sets in. You need to get all the water out of the pipes.
There are two main ways to remove all water from the pipes and sprinklers before the first freeze -drain the water out through drain valves, or blow the water out, using air. Seems simple right?
Not so fast. If you live in a colder climate (like Northern Colorado) you must first make sure the mainline shut-off valve is freeze-proof. It must be completely evacuated so there will be no freezing water left to damage it. If you let it freeze up, your main valve will sustain damage, and your system won't work in the spring.
As for removing the water, both of the two available drainage methods have advantages and disadvantages.
Chose to use valves to drain water, and you will need to be certain they are installed at each low point in the piping. Opt for a manual draining system and you'll need to be out there, manually opening the valves. Select automatic drain valves, and they will open themselves whenever the pressure drops too low in the pipes-however, they often stay closed if they haven't been routinely opened.
This method uses an enormous air compressor to blow water out of the pipes to fully empty them before winter. There are, however, a lot of things that can go wrong with this method, and one tiny mistake can mean you no longer have a working sprinkler system in your yard.
