Winter Sprinkler System

This article will discuss sprinkler systems, how they are affected by Winter, and how you can prevent them from malfunctioning throughout the season.

With Winter’s cold temperatures on the horizon, it’s more important than ever for you to take steps to prevent their sprinkler systems from freezing up and leaving you with a hefty replacement bill. So, with this in mind, we’re going to look at some of the things which can cause this to happen and how you can prevent it from ruining your sprinkler system – so, let’s jump right in.


What Causes Sprinkler Systems to Freeze?

There are two types of sprinkler systems available – dry pipe and wet pipe – and both can be at risk of freezing.

A dry pipe sprinkler system is controlled by pressurized air and thus, there are no water particles in the sprinkler system initially and there’s a lower chance of the system freezing. However, over time moisture particles will be absorbed into this pressurized air and once some of those particles freeze against the pipes, they can build up an ice blockage inside of the system.

On the other hand, a wet pipe sprinkler system is controlled by pressurized water which has already been pumped throughout the system, meaning that as soon as the fire breaks out and the system is triggered, water is released. Of course, given that the pipes are full of water, it’s very likely for it to freeze when cold temperatures hit.

Regardless of the type of system that you have, you must know how to prevent it from freezing.


How to Prevent a Frozen Sprinkler System

Turn Up the Thermostat.

Even if you’re going to be out of your home or workplace for a few days, you should still have the thermostat at a reasonable temperature. Having it set to around 50-60 degrees Fahrenheit is ideal for preventing sprinkler damage.

Have Your System Inspected.

Have your system inspected during winter time to make sure that there are no cracked pipes and that all of the equipment is working as it should be. If there are any leaks in the piping (especially if the piping is connected to an outdoor compressor), then a crack could result in severe damage.

Insulate the Pipes. Insulation helps to retain heat within a specific area and by having your sprinkler system’s pipes insulated, you can make sure that they don’t drop too low temperatures as quickly as they would otherwise.

Remove Snow and Ice.

This is a pretty difficult step to take, especially if there are snow and ice on your roof. However, snow and ice make the environment around them colder and if your building is surrounded by them, the temperature inside will quickly drop. Take the time to shovel all of the snow away from your building, scrape the ice off of your windows, and although it might be difficult, have the snow removed from your roof.

It can be dangerous to walk around on your roof, especially if you don’t have the proper safety equipment, so don’t take this risk without properly preparing. Because heat rises, depending on your building’s structure you may be able to eliminate the snow on the roof by turning up the thermostat. If you have an attic, putting a portable radiator would also melt the snow on the roof.



Taking these steps to prevent a frozen sprinkler system is worth it, especially when you take into account the cost of replacing it and how the system would be pointless if a fire was to break out. Do the right thing and take the steps to prevent your sprinkler system from freezing, it’s undoubtedly worth it in the long run.
