Wichita, Kan. -- You can expect to wake up to freezing temperatures and that has a lot of local irrigation companies busy. They're all trying to get their customers ready before the next big freeze.
Kirk Richards, owner of Apex Lawn Irrigation, says they have busy winterizing customer's irrigation systems.
To winterize a system, they shut off the water supply, connect their hose, and blow out all the water that's still in there.
"It pushes all the water out of the system so it doesn't expand and break the plastic on the heads and on the piping," Kirk Richards said.
Richards says he's been busy the past few weeks.
"We have about 6,000 customers and we've done about 5,000 this year," Richards said.
They've also been busy repairing systems that have already frozen over and broke.
"A few weeks ago, the first cold snap, we had some back flows freeze over since they're above ground they break first," Richards said.
Richards says the average winterization costs about $75 dollars. Skip one and your backflow preventer could freeze and crack, that would cost more than $100, plus installation fees.
If you have haven't blown all the water out from your irrigation system yet, you can still protect during the cold nights ahead by wrapping your backflow preventer with something like a blanket and then putting something waterproof over it like a trash bag. That will cut down the windchill a little and could keep it from freezing over.
