Kept teasing and teasing but it's finally here...RAIN!

Because the water is so hard here that you need to drain water to get some of the calcium out and bring your CH down, also allows salt pools to drain water and bring down the salt level which increases over time due to the sodium level of the water here that keeps getting added to compensate for evaporation. If you chlorinate your pool you eventually get to much CYA as Cyanuric Acid is added to the pucks and the level will get too high.

The only way to reduce the calcium level, salt level or Cya level is to drain water which a good rain lets you do without having to pay to refill with tap water.

Hmmm good info.

Far east Mesa here and it's been POURING all morning. I had to backwash my pool or it would have over-flowed. It was trash day in my neighborhood the run-off was so heavy, several empty trash cans were floating down the street.
According to the Flood Control District of Maricopa County, from the rain gauges located on the hill just behind my house, it looks like we got 1.5 inches in the last 3 hours.
I'm hoping it rains good for the next few days to fill up all the lakes.

Evaporation only takes the water, it leaves the salt, calcium and cya in the pool. When new water is added by your auto fill to compensate for the evaporation it puts more calcium and sodium in the pool so eventually the levels get way to high and the only way to bring them down is drain water to keep them in check. Using chlorine pucks adds cya each time and eventually that level gets too high and causes your chlorine to no longer be effective.

I drain some water every year and add new water from the tap. I've been able to skip this procedure a couple years when it rained enough that I got to drain some water due to my pool level being too high.

It's only a benefit if you actually drain your pool after a good rain. If you just let it evaporate back down to the proper level there is no benefit as none of the salt, calcium or cya leaves the pool. Turn on the filter and let the new rain water get mixed up with the old water and then drain the pool down to the proper level and let it take a bunch of salt, calcium and cya down the drain. On a salt pool you have to add cya yourself so when you drain the excess rainwater it takes some of the cya with it and eventually you'll have to add some more cya (called conditioner or stabilizer). Cya is cheap and easy to keep at the proper level in a salt pool since it isn't constantly added with the chlorine pucks.

Flooded streets, downpour all morning, still dribbling. Love it! Although my VW bug bogged out on the way to the store and I had to for go the shopping until the rain let up. All in all pretty fun experience, we rarely get weather events of any kind, so I enjoyed it.
Yes, I played in it! lol

PREDICTION: Monsoon 2013 is history. Today is the last day of monsoonal type rain and dew point will be dropping off to fall like levels over the next few days. Hooray! I can't wait for the dry air to return.
