SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

It could but I live in northern MI where it has been down to 20 degrees but warms during the day and I have not had a problem. If you are really concerned just make sure anything outside and above ground doesnt have water in it.

Have you ever blown your system out? Is ther some above ground outside pipes? If you have a compressor You will need to shut off the sprinkler main inside your house. Some where down stream from that you need to connect your compressor. For this situation you really don t need all of your lines clear like you will for normal winterization. So after you are connected then You need to open all of your sprinkler valves. You shouldnt let the compressor put out more than 70 psi and blow out the lines. THen close your valves again. What this should accomplish is the above ground lines are blown out. No water in those. For one noght of freezing this will be fine. Leave the sprinlkler main off until you wont have freezing temps. This is a bit simplified so if you dont follow my instructions let me know. Please note this is not how you would blow out the lines for normal winterization but will work for this situation.

So, pipes still in one piece?
