Send us Fan Mail How should you dispose of pool water after you've tested it? It sounds like a simple question...until it isn't. Wayne Ivusich and…

But I got an odd email from him a couple days ago, and it pretty much was talking about he has a commercial customer that when they test their water, okay, for whatever, it really doesn't matter what it's for, pH, alkalinity, salt, whatever, and they dump the treated sample back in the pool, they got kind of a finger wagged at them by a health official that said they can't do that.

I don't think there's a single state that regulates what you do with that water you've been adding reagents to, what do you do with it? And that prompted a further discussion with Q about, you know, what do you do? And I thought I'd also post it in the Certified Pool Operators-CPO Facebook website that both Steve and I are admins for.

What do you do? With the water, if you tested for, say, pH, what do you do? Do you toss it back in the pool? Do you dump it someplace else? What do you do? Well, personally, I was always taught that you should never dump it back in the pool.

It's not going to damage anything because remember you're talking a few milliliters of water versus hundreds and thousands of gallons of water.

But if you have a customer standing there watching your every move and you do that, that's just simply poor technique.

So what do you do with the water? Well, What I always did was I carried an empty bucket with me and added some water to it.

And then I would dump my treated samples into that bucket filled with water and then dump that product or not product, but dump that residue into a drain at another location or back in the office or wherever.

You know, are you just simply lazy dumping it back in the pool? Do you, you know, do you treat the customer courteously and put it back in this bucket? What do you do? And so the responses I got back on the Facebook page were, a couple of them were kind of funny, but one was, I must have a lot of time on my hands when I told the guy, well, I am retired.

And then I pointed out the fact, as did Rudy, that if you're using a Taylor test kit, I am the person who wrote those instructions.
