You might not think about it often but it really does matter because your backflow device plays a silent but a very crucial role in keeping contaminated water out of your home’s supply. 

But the problem here is that. When it is installed in an outdoor utility box well then it is just sitting right in the path of harsh cold winds, rain and freezing temperatures.

And at Backflow Joe’s we have seen this story unfold too many times to even count on our fingers because when the first frost hits, the water inside expands, the brass housing cracks and suddenly you are looking at a full system replacement. 

So in this guide we are going to show you how to protect your backflow device with some of the best backflow maintenance tips so you can have a warm and a healthy winter experience.

Why Outdoor Utility Boxes Aren’t Always Enough?

Yeah your outdoor utility box might look protective but most of them are just thin metal or plastic shells as they are designed for easy access and not insulation.

And when the temperature drops below freezing then the metal conducts the cold straight to your backflow preventer assembly which then starts creating the perfect setup for frozen water and burst parts.

So if you want some real protection think beyond the box because your backflow assembly needs insulation and heat retention and not just enclosure.

Plus if thinking is too much then might I suggest Calling Backflow Joe’s as they will do all the thinking for you when it comes to protecting your irrigation backflow.

Add Insulation The First Layer of Defense

Your best friend here is insulation which is a simple insulated backflow cover or thermal blanket that can make a huge difference in protecting your assembly.

And don’t forget to choose a waterproof or a UV resistant model that fits really snugly over your utility box.

Here Are A Few Field Tested Tips From Backflow Joe’s services Team:

• Use closed cell foam or fiberglass wrap inside the box for extra protection.

• Don’t forget the valves and exposed pipes because they can freeze first.

• Avoid over sealing because the airflow prevents condensation buildup which can cause corrosion.

Plus if you want to prevent freezing your backflow assembly then make sure to check out Oatey’s Guide on Winterizing Pipes and Prevent Frozen Pipes which shows you a complete walkthrough to make a more foolproof plan to stay protected.

The Heat Tape A Pro Move That Pays Off

If your property sits in a region with hard freezes then please go the extra mile and install heat tape or a heating cable around your backflow device and pipes.

And let me tell you this isn’t a DIY job for everyone because these cables require precise installation and safe electrical connections.

But when done correctly they automatically activate at low temps and keep water moving which then starts preventing ice buildup inside the outdoor utility box backflow assembly.

At Backflow Joe’s we often pair insulation and heat tape for a two layer defense system that performs even in the coldest coastal nights.

Keep It Nice And Dry Inside

Moisture inside a closed box is trouble waiting to happen.

Because rain, sprinklers and condensation can all creep in creating corrosion and even short circuiting heat cables which is serious trouble.

So To Stay Ahead Make Sure To:

• Drill out those small drain holes at the base of the box.

• Add a few silica gel packs to absorb all that moisture.

• And keep the area around your box elevated so runoff doesn’t pool at the bottom of the base.

Also here is a backflow maintenance tip we share with every customer which is that always inspect your utility box once a month during winter for moisture, rust or insect nests.

Annual Testing Yep Don’t Skip The Professional Check

Even with proper protection your backflow assembly needs an annual backflow testing and inspection.

As this test ensures that the checked valves and relief assemblies are working correctly even after months of weather exposure.

And ignoring it could mean undetected leaks or worse contaminated water flowing backward into your system and if you want to know more then make sure to check out WSSC Water’s Guide which talks about just how vital this process is. 

Plus Backflow Joe’s certified technicians run these tests with document results for local compliance and catch potential damage before it becomes costly.

Bonus Tip: Do A Seasonal Shutoff When Possible

If your backflow device only services your irrigation system then consider shutting it down completely during winter.

Because draining the system and leaving valves open prevents trapped water from freezing.

And for customers with complex irrigation networks well Backflow Joe’s offers seasonal backflow maintenance where we handle the entire shutdown, inspection and restart process when spring arrives.

If You Ignore It You Are In Big Trouble

A burst backflow assembly can cost anywhere between 300 dollars and 800 dollars to replace and I am not even counting water loss or property damage.

So that is why we say it every year that a 40 dollar insulated cover always beats a 400 dollar repair bill any day.

And our backflow preventer winter care service is specifically built for property managers and homeowners who want long term peace of mind. Give it a try you won’t be disappointed.

Protect Your System Before The Cold Hits

Your backflow device is one of the smallest parts of your plumbing setup but it is what it is and protects your entire water supply so don’t let it fall victim to the next freeze.

With Backflow Joe’s help homeowners and property managers can keep their systems in compliance, frost proof and ready for every season.
