Backflow Preventer Enclosure

Backflow preventers stop waste water from travelling back up pipes and systems, and contaminating drinking water. While backflow preventers protect our water, they need to be protected from freezing temperatures. Just like water pipes, unprotected or poorly insulated backflow preventers can freeze and burst. In today's blog post we discuss how a backflow preventer enclosure can help you avoid big headaches when the temperature drops.

Protecting Your Backlfow Preventer

Public water supply systems normally maintain enough pressure to enable water to flow. However, water pressure can be reduced or fail from a pipe freeze. This is why a well maintained and protected backflow preventer is critical.

Unfortunately, even when a backflow preventer is professionally insulated, some insulation options can fail.

As you can see here on the right, this backflow preventer assembly was professionally insulated, however the insulation was not adequate to protect it from our last, hard freeze.

Insulating Backflow Preventers

poorly insulated backflow preventer

Here's a real problem waiting to happen - a backflow preventer hastily wrapped in fiberglass insulation.

Not only is this insulation job an eyesore, but because the fiberglass insulation is made from strands of glass fiber, it loses its thermal resistance when it gets wet.

Rain followed by freezing temperatures will mean this backflow preventer assembly is at risk of failure.

Our solution is to protect our clients' backflow preventers in a Geaux Box.

Backflow Preventer Enclosures

The Geaux Box is a sturdy fiberglass container with a 2" foam center. Like cages, the Geaux Box protects the backflow preventer from accidental impacts. Best of all, none of our clients backflow preventers protected with a Geaux Box has ever frozen.
