In most parts of the country there is a real concern about freezing and frost damage to a drip system during winter. There are two areas of concern: the beginning of the system (timer, valves, and filter) and low spots in the system where water may settle.
- Battery timers, filters, and regulators should be brought indoors with the batteries removed from the timers.
- When the battery timer is removed from the faucet and system, use the HPLUG to plug the beginning of the mainline tubing or use a plastic bag over the opening. Do not leave the lines open.
- After the main water supply is shut off, open all manual valves and set automatic valves to manual open. Remove all end fittings, drain any water, and then loosely replace the ends.
- In flat areas elevate the mainline to make sure all water drains out of the fittings.
- For low spots in the mainline tubing, either use a flush valve or insert a basic emitter at the lowest point.
- Another practice is to blow compressed air through the lines after opening the end cap.

How does one go about blowing compressed air through the lines?
ReplyDeleteWhen blowing out your lines with compressed air make sure that all ends are off the irrigation system to prevent damage. An air compressor can be used to blow out the lines, to ensure that no damage will happen when blowing out lines do not use more than 30 PSI to do so.
ReplyDeleteI have a small air compressor and purchased an adapter from "Vibrant Yard Company" - available on Amazon. Search for "winterize sprinkler adapter" and it should be the first hit. Get the one with the shutoff valve - that way you can charge up your compressor and send high psi down the sprinkler line to blow it out.
ReplyDeleteMy system is pretty small, so this works for me. If you have a huge network, you may want to hire a professional to winterize your lines.
