Sprinkler Blowout Process Shirley

Here's Exactly What We Do

First, we shut down your entire system and turn off the main water supply to prevent any new water from entering the lines.

Next comes the critical part: using our commercial-grade air compressor, we blow out every zone of your irrigation system. Working one zone at a time, we use the compressor to blow the water out, until air is the only thing coming out of the sprinkler heads. This isn’t something you can do with a basic home compressor.

We also drain your backflow preventer and shut down your irrigation controller. Professional service can be completed in around half an hour, depending on the number of zones in your system. When we’re finished, your system is completely empty and protected from freeze damage.

If you live in the region of Long Island, New York, you know winter temperatures may dip well below 32°F. That’s why we also inspect your system for any visible issues that could cause problems when you restart in spring. If we spot potential problems, we’ll let you know before they become expensive repairs.

We recommend winterizing your irrigation system between early October to mid November. On Long Island, our weather can drop below freezing as early as October, so don’t wait too long.

The best approach is to schedule your service in early fall, before the first hard freeze. It is best to call around mid October to make sure you’re on our list for the season. Once temperatures consistently hit the mid-30s at night, it’s time to get your system winterized. Waiting until after the first freeze could mean it’s already too late to prevent damage.

If you don’t get your system winterized, once the ground freezes, the pipes will burst from the water that is left in the lines. If the main line is not shut off, once that pipe bursts, you’re going to have a constant flow of water coming out into the yard.

Your water bill will be high because of the wasted water usage and in the spring you will have to rerun a lot of the lines. The manifold is made of PVC which can shatter from expanding and contracting during the freeze/thaw cycle. The damage isn’t just expensive to repair – it can flood your property and create a real mess.

Typically, homeowners can expect to pay between $60 and $120 for a professional blowout service. This cost varies based on factors like the size of your sprinkler system and local service rates.

Winterization is cheap compared to the money you will spend repairing or replacing a damaged system. When you consider that spring repairs can cost hundreds or even thousands of dollars, professional winterization is one of the smartest investments you can make. We provide upfront pricing so you know exactly what to expect, with no surprises.

While it’s technically possible, we don’t recommend it. Unless you are experienced, do not try to execute the “blow out” method on your own, as too much air pressure can seriously damage your system.

Professional winterization requires commercial-grade equipment and knowledge of your specific system layout. Having a “jack of all trades” who may not have the know-how to use a larger compressor could result in a dangerous circumstance. Not only would those around be at risk, but the irrigation system could be left with water in the pipes, damage the irrigation system, or the water could be redirected into the home and cause flooding. The small cost of professional service isn’t worth the risk.

Professional service can be completed in around half an hour, depending on the number of zones in your irrigation system. Larger systems with more zones will take a bit longer, but most residential properties in Shirley can be completed quickly.

A clear indication of an amateur would be the time, as someone using a system not designed for irrigation systems would take upwards of three hours to complete the service. Our professional equipment and experience mean we get the job done efficiently without cutting corners on quality.

This is the most important (and often most overlooked) part of the process. Simply draining water usually isn’t enough—small amounts of water left in the lines can still freeze and expand.

Manual draining relies on gravity and valve systems, but water always gets trapped in low points, fittings, and sprinkler heads. Professional blowout service uses compressed air to force every drop of water out of your system. The winterization of a sprinkler irrigation system is the process of using a compressor to blow the water out of the system, to prevent the pipes from freezing. This complete removal is what prevents freeze damage.
