## Description

The Blue Wave Rectangular In-Ground Pool Winter Cover offers superior off-season protection with solid polyethylene construction built to withstand harsh weather conditions. Designed with a durable 7x7 scrim count and heat-sealed seams, this inground pool winter cover resists tears, sun exposure, and harsh weather conditions. A black underside minimizes algae growth by blocking sunlight, while a 4-ft overlap ensures complete coverage over pool edges, securing the fit and helping prevent water contamination from debris. This winter pool cover includes reinforced grommets spaced every 2 feet, allowing even tension when secured with the included vinyl-coated steel cable and locking winch. Its robust fastening system helps keep the rectangle pool cover in place during wind, snow, or heavy rain. Built for ease of installation and maintenance, this pool cover for inground pools comes with an 8-year limited warranty, including 1-year full coverage, providing pool owners with peace of mind throughout the winter. Available in a wide range of sizes, this swimming pool cover fits nearly all standard rectangular in-ground pool dimensions: 12-ft x 20-ft, 12-ft x 24-ft, 14-ft x 28-ft, 16-ft x 24-ft, 16-ft x 36-ft, 16-ft x 32-ft, 18-ft x 36-ft, 20-ft x 40-ft, 20-ft x 44-ft, 25-ft x 45-ft, and 30-ft x 50-ft.

Review: This product was a perfect fit for my 14' x 30' rectangle pool - This product was a perfect fit for my 14' x 30' rectangle pool. Please know that this product has a 5' overlap, meaning that the actual dimensions for this product is 21' x 37'. The overlap is necessary and convenient because you want to have some lag that allows the cover to "droop" into the pool and touch the top surface of the water, and so you have enough of the cover material to weigh down so the wind doesn't blow it out of place. The material itself is decent, it is not going to be super thick, but feels tough enough to withstand a few winter usages if maintained properly. You get what you pay for in this case, and for this low price when compared to other vendors, it was an excellent deal. This is the first year so it's all good so far. Note: I had help unfolding the cover since it is large. I laid the cover out in the sun for a whole day to try and get rid of the creases that formed when the cover was packed. Instead of buying expensive water tubes, which all have received horrible reviews for their quality, I went to the nearby home improvement store and bought 10 of their 5-gallon buckets to use as the weight to hold down the cover. In order to minimize friction/damage to the cover, I cut out square pieces of 1-inch styrofoam and placed it between the cover and buckets.

Review: Don't buy from this company ... rapid deterioration and the warranty is worthless - The BWC752 8-year warranty cover as installed on the pool in October 2024. In January, we noticed that the fabric of the cover was deteriorating, and the fabric laminations was developing small square holes. This was happening on all areas of the cover; on the apron where the water bags are located, and on the curved surface from the edge of the pool to where the rain water gathers. In coastal NC, UV affects tarps and covers over time, but never have we seen a cover deteriorate so quickly. So we submitted a warranty claim ... below is the most hilarious reason ever given to deny a claim: As your pool is 18x36’ and the cover is 20x40’, this leaves 2x4’ of extra material. Over time, rain, snow, ice, and other kinds of debris collect in the center of the cover, and because the cover is so much larger than the pool, this causes it to sag in the center more than it was designed to do, holding more weight than it was designed to hold. B Glynn, Bluewave Products. In reply, I sent a diagram showing the stress strain curve of the cover and the following note (see photos): Dear Brendan, The sag on the cover is not to a function of the border width as you claim but the depth of the pool water. Our pool is always pumped out to 12” freeboard. The pool is covered as normal and secured using water bags (as shown in the photo). The water that gathers does not cause any sag in the center as you suggest: water is a fluid that behaves according to the force of gravity, and will always remain flat. Unless you have a cover that has created some form of polar vortex, there cannot be any sag in the center of a pool (at least not on Planet Earth). And your claim “because the cover is so much larger than the pool, this causes it to sag in the center more than it was designed to do, holding more weight than it was designed to hold.” is so far out in left field that it made me gasp! The weight carried on the cover (and therefore the downward force exerted) is a function of the area of the pool (in this case 18ftx36ft). For each inch of rainwater, the weight of water is 3,370 pounds, distributed over 648 sq. ft. (providing a force of 5lbs per sq ft on the stress strain radius). The weight CANNOT VARY ACCORDING TO THE SIZE OF THE COVER ONLY THE SIZE OF THE POOL. The failures of your cover are clearly delamination of the fabric and it is occurring within the strain radius, as well on parts outside of the stress/strain radius such as the parts of the cover underwater, and on the border area. Clearly, your company is using a material poorly suited for purpose.
