Pool School

The whole closing in order: balance, shock, blow out the lines, plug them, lower the water and cover.

From the water balance to the air pillow and the cover's cable, in the order to do it.

Which blower to use, the order to clear each line, and how to hold the main drain with air.

A few inches under the skimmer for a solid cover. Under a safety cover the maker's manual decides.

Only a few inches, and with a skimmer plug not at all. Why the pool is never drained.

Count the cover's edge, not the pool's, and how full to fill each tube.

Order by the pool's size, not the cover's. Which cover fits each round and oval pool.

Which air pillow goes with which pool, and how full to fill it.

Enter the pool's size and the temperature you want. Get the heater size and the hours to heat.

Which one heats faster, which costs less to run, and what cold air does to a heat pump.

What each Pentair, Hayward, Raypak and Jandy code means, and the part it names.

Mesh for most pools, and the three cases where solid is the better cover.

What the label has to say, and the three classes the standard sorts covers into.

One anchor for each strap, the hole each one needs, and how far back from the edge they land.

When a pool needs a cover cut to its outline, and the two ways to order one.

What shock does, when the pool needs it, and how much to use for your gallons.
