Question 1

How do I know if my sand filter has enough sand?

Accepted Answer

•

An easy way to know whether your sand filter has enough sand is to check how full the filter is and what the sand looks and feels like. The filter container should be two-thirds to three-quarters full of sand. Look for interior marks indicating the ideal sand level. If you put your hand into the sand, it should flow through your fingers without clumping. The filter pressure gauge is also an easy indicator—the right amount of sand leads to normal pressure, while too much or too little sand can cause high or low pressure.

Question 3

How do I know if my pool has a leak?

Accepted Answer

•

Losing some water from splashing and evaporation is normal. However, if you notice a rapid drop in the water level or are adding water more frequently than usual, you might have a leak. Other common signs of a pool leak include:

Unexplained soft, mushy, or wet spots in the yard.
Cracks in the pool's structure or falling tiles.
Higher-than-normal water bills.
Persistent algae growth or water discoloration.
Standing water near the pump, pipes, or other pool equipment.

Question 4

What shape pool is easiest to maintain?

Accepted Answer

•

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.

Question 5

Can you have an automatic pool cover with a saltwater pool?

Accepted Answer

•

You can have an automatic pool cover with a saltwater pool, but it’s important to know that the small levels of salt in your pool can eventually corrode the metal parts of the pool cover. This means you’ll have to keep your unit clean, especially the reels, pulleys, and tracks. As with any other pool cover, test your chlorine levels weekly and keep them on the lower end of the threshold.
