With cold weather and fall right around the corner, many homeowners are looking for the best-insulated backflow covers and enclosures to provide freeze and frost protection.
As more and more building codes are changed to require water backflow prevention valves be installed in residential neighborhoods, the need for dependable, low-cost options has risen significantly over the past few years.
How To Choose The Best Insulated Backflow Covers And Enclosures
The first step is to verify how much insulation protection, or R-value, will be necessary to provide frost and freeze protection. At the minimum, most use at least R4 r-value, with 10 and 13 more popular. When it comes to choosing insulated backflow covers and enclosures it’s best to go with more R-value vs less. Simply because it’s more or less impossible to have too much insulation when it comes to insulating a backflow prevention valve.
In situations where a water well pump is exposed above ground and is being covered and insulated, then one must be wary of using too much insulation which could limit ventilation and cause the well pump motor to overheat and fail.
However, in the case of backflow valve freeze protection, one need not worry about over insulating because there is no electric pump within these types of valve installations.
One of the most important steps in choosing the right insulated backflow covers and enclosures is to carefully measure the height, width and length of the actual backflow preventer installation. Include the piping as part of the measurement. Everything that is going to be covered needs to be included.
It’s important to consider how much space the insulation is going to take up inside of the hard backflow cover. The last thing you want is too much insulation preventing the cover from closing and latching.
The DekoRRa brand insulated backflow covers and enclosures we sell are nice because the R-13 insulation included with the cover is appropriately sized to fit within the actual backflow enclosure. This type of package deal is easy to install and fool-proof as it takes a lot of the sizing guesswork right out of the equation.
Avoid Fiberglass Backflow Covers And Enclosures
Insulated backflow covers and enclosures made of fiberglass should be avoided if at all possible. Fiberglass is heavy, prone to U.V. damage and doesn’t have any give to prevent cracking from impact damage. Units made from polymer resin are usually stronger and can withstand more damage.
It’s also a good idea to focus on models with a means of locking the cover down. While practically any type can be broken into given the right tools and enough time, having a locking system is a great way to deter thieves and vandals who will hopefully see the lock and wander off to find an easier target instead.
Just remember that the cover is going to need to be removed on occasion if the backflow valve should require testing, inspecting or maintenance of any kind. So a locking system that is manageable and easy to unlock is key.
Fake rock covers are also becoming popular as insulated backflow covers and enclosures. What’s nice about going the fake rock route is how well they can blend into the surrounding landscaping. Being able to totally disguise that ugly metal backflow valve under a realistic fake rock is a real bonus to many homeowners looking for the best-insulated backflow covers and enclosures.
