How far off can a pool be unlevel?

• <div><p>An aboveground pool should be level within 1 inch—and it starts to become unsafe after a couple of inches. Any slope will lead to an uneven distribution of water, which will put pressure on your pool’s structure, wearing down the pool liner. In certain cases, it could cause your pool to collapse. Even if you’re within a safe window, you may still notice that the water level is uneven.</p></div>

Q: Do you have to drain your pool to convert to salt water?

• <div><p>Generally, you do not need to drain your pool to convert it to a saltwater system. The main exception is if you have used an antibacterial agent containing polyhexamethylene biguanide to sanitize your pool, as these sanitation products do not mix well with saltwater systems. If this is the case, you will need to start fresh. You can either drain the pool or treat the existing water with a high dose of chlorine to remove the antibacterial agent. If you choose the chlorine treatment, wait several days to allow the chlorine to work before proceeding with the conversion. If you are unsure whether this applies to your pool, consult a pool technician.</p></div>

Q: Why am I losing water in my inground pool?

• <div><p>In-ground pools lose water naturally due to wind, heat, and humidity. They also lose water from the kiddos' cannonball competitions. But be mindful of the water level. If it drops too low and the pump draws in air instead of water, it will likely be damaged and require repair or replacement.</p></div>

Q: What is the least expensive time of year to build a pool?

• <div><p>Off-season pool-building prices often align with the time of year you're least likely to use a pool. Many contractors offer deals in the late fall and winter to bolster the slow time of year. However, if you live in an area with freezing winters, you'll need to wait beyond the final frost and threats of extreme weather.</p></div>

Even if you&rsquo;re within a safe window, you may still notice that the water level is uneven.</p></div>

Q: What shape pool is easiest to maintain?

• <div><p>Rectangular pools, particularly those made of vinyl or fiberglass, are the easiest to maintain. The long, straight sides, right angles, and smoother surface make regular cleaning a breeze without having to maneuver into curves and nooks. Rectangular pools also tend to be standard sizes, so you may have an easier time when it comes time to replace liners, covers, and other parts.</p></div>
