There are only five ways an oval above ground pool’s straight sides can be off or crooked. FIVE REASONS WHY THE STRAIGHT SIDES OF AN OVAL POOL ARE OFF This can often result in the straight sides of the oval-shaped pool not coming out perfectly straight. ![]() So with an oval pool then, the end product can be off more because it has more non-precise parts coming together, which means the overall tolerance can add up to more. Every other part that goes together is made to have some play and is not machined to go together very precisely or even well most of the time. It has to come together and bolt somewhat perfectly. There is no part of an above ground pool that has to fit together perfectly with the exception of the wall. Ovals have two to three times the amount of parts, need to be rounded AND squared, and have a portion of the structure that needs to be leveled from front to back instead of only side to side. The difference in design from a round pool to an oval one is considerable. OVAL SHAPED ABOVE GROUND POOLS ARE MUCH LESS PRECISE THAN ROUND POOLS I think it’s important to know this when attempting to DIY a pool install. In the realm of installing above ground swimming pools, “perfect” is something closer to the rough carpenter’s definition over the machinist. A really talented rough carpenter can build things in his trade that are off a full inch and that’s considered perfect. For a machinist making parts for NASA, perfect may be something within 1/1000 of an inch range. The term “perfect” means something different to each of us and it may depend largely on what you do for a living and/or your personality. In truth, they’re not even close to perfect. DON’T EXPECT PERFECTIONĪs at least a semi-perfectionist and builder of above ground swimming pools for more than 35 years, I can tell you something without any uncertainty. In many other cases, the pool isn’t straight because the design of the pool model wasn’t precise enough. In most cases, when an oval above ground swimming pool’s long sides aren’t straight, it’s because one or more of the buttresses aren’t level. The quick good news is that the pool is probably fine. If you have found this article, then chances are you are having some issues with the way your new oval above ground swimming pool is looking. ![]()
