Ensuring a Proper Fit

A properly fitted insulated cover will easily slide over the backflow prevention assembly without drooping or sagging.

Backflow Specialty Equipment Company manufactures and stocks sizes that meet most of the requirements for pipe sizes up to 2”. Our stocking distributors should have these common sizes in stock.

Custom sizes are available. Custom orders will be manufactured in accordance with drawings and/or written size information.

All sizes are available as pads as well as “bags”. The pads have grommets on the sides that allow the pad to be snugged down against the pipe for protection against the wind. The use of nylon wire ties allows an inexpensive installation.
The following criteria should be considered when sizing an insulated bag:


• The lay length of the installation: Measure the distance from the outside of the inlet riser elbow to the outside of the outlet elbow. Add approximately 3” to 4" to this length to ensure that the bag will slip on or off the assembly with ease.
• The location of the Test Cocks: If the backflow prevention assembly has side mounted test cocks, add approximately one to two extra inches to the length of the bag.
• The location of the Relief Valve: If the backflow prevention assembly has a side mounted relief valve, add approximately 2” inches to the length of the bag.
NOTE: If the bag or pad does not reach the ground, it may be desirable to install foam pipe insulation on the exposed pipes below the bag or pad.

Standard Sizes:

The first dimension listed for each size is the approximate inside length, while the second dimension listed is the approximate inside free height. Please note that the installation over which the cover is being installed may alter the effective length and height of the cover. Dimensions may vary slightly from bag to bag. Bags are sized while the bag is lying flat; therefore, pipe diameter measurements also need to be considered while sizing.
