A Lawncare MVP sprinkler Blowout/Winterization includes the following.
Please note that if there is no blowout access through the backflow or drain, the lateral and main sprinkler lines will be left open to drain naturally.
We usually perform sprinkler blowouts / winterizations from about the first of October through the end of October. You can call any time of year to reserve your spot on our schedule. Since we can only perform sprinkler blowouts / winterizations for such a short time, reservation space is limited. We highly recommend getting on our list early; don’t wait until the end of the season when a freeze is in the forecast, as there is a chance we might not be able to complete your winterization before the freeze, if at all.
Your sprinkler blowout / winterization cost will depend on the size of your sprinkler system. We charge our normal sprinkler repair rate, plus a $25 compressor use fee. Most properties can be completed in about 30 minutes, or less. If you have a lot of sprinkler zones it will take longer.
Yes, and no. While you can hook your home air compressor to your sprinklers, most home compressors don’t have enough air volume to sufficiently blow the water out of your pipes, which leaves water in the lines and increases the risk of freeze damage. A proper blowout requires enough air volume pushing through the system, no matter how much pressure (PSI) or force the air has. We use a large compressor mounted on a trailer, which costs $20,000+ and puts out 185 cubic feet of air every minute (CFM). By comparison, most home compressors put out around 4-10 CFM. While you can raise air pressure (PSI) on your home compressor, you can only get the right CFM with a bigger compressor. It is also important to note that most sprinkler systems are designed to operate at about 40-60 PSI, and higher PSI can damage and blow off sprinkler heads.
