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
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.
