Finally, a fast, easy, and affordable well pressure tank cover for residential and commercial properties. The DekoRRa Model 114 Mock Rock pump house enclosure is available with or without insulation for added protection in cold weather. Cover, protect, and insulate water well pump components while blending them into the natural landscape with this beautiful and easy-to-use fake rock cover. All of the texture and color are molded into the artificial rock’s exterior walls, so there is never a need to paint or resurface. Advanced UV protection also prevents these Model 114 faux boulders from fading over time.
IMPORTANT: Please use the interior dimension information below for sizing details.
The Model 114 Mock Rock is constructed of thick polyethylene designed to withstand extreme weather, intense sunlight, and impact damage from things like string trimmers and stones thrown from lawn mowers. Everything is molded into the exterior rock walls—the textures, the color, and the UV protection. It’s a zero-maintenance design that will never require any painting, washing, or repair. Actual particles of organic material are molded into the walls of these fake rocks, creating a gritty, rugged texture with incredibly natural color variation.
You can quickly and easily disguise pumps and well pressure tanks as gorgeous faux rock landscape boulders. The hollow, lightweight design can be tilted up and over by one person, allowing for easy access, inspection, and maintenance of components underneath the enclosure. Patented flanges molded into the base of the exterior walls serve as anchor points, through which the included ground stakes are driven to secure the boulder to the ground and protect it from the wind.
The Model 114 is available with two types of additional insulation:
-
The Pro-R version features a durable R-4 insulation coating added to the interior during manufacture. This Pro-R option is only available in the riverbed color.
-
An R-13 insulation bag is also offered for even more protection from cold weather damage. The insulation bag is slipped over the pressure tank prior to installing the rock cover.
Both of these options can be added using the drop-down menus next to the Add to Cart button.

This rock rescued us from having to look at the well and pressure tank out back. We were worried it would look fake but pleasantly surprised by the quality and realism. The vents we have in it are not too noticeable either.

I almost had a heart attack when I saw how large this artificial boulder looked on the truck, but once we got it out in the yard and covering our water well pressure tank I really liked it alot. We got the Sandstone color and it looks beautiful.
