The magnets are on the inside. No apparent wiring. While our water is hard in terms of Calcium (60 ppm out the tap) I don't believe we have a particulate or dissolved iron problem (which magnets wouldn't help with anyway). I'm inclined to agree with James that it is a gimmick. Thanks for...

Yes. I stuck a kitchen knife blade inside and they are magnets. Five rows to be exact :)

I removed my old (ancient) pump last weekend and replaced it with an intelliflo. One part of the plumbing removed was this inline gadget. Inside of it appear to be magnets (with some attached metal shavings). Is that what it is? Is it worth putting back in?

Thanks for everyone's feedback- I'm going with the Intelliflo!

Thanks for those insights. I'm going back through the intelliflo manual now.

In the 10 years we've lived here I've seen the temperature go as low as 15F, and one year it did go low enough to freeze and crack the manifold on the pool heater. So yes, freeze protection of the pumping equipment is a requirement. I'm not aware that the intelliflo has freeze protection; I...

Hi Mark. Intelliflo pumps would be my first choice but I need the external timer because of the freeze protection built into it (it has saved my butt a few times).

My pump started making periodic screeching noises about a week ago (or that's when I started noticing it) and yesterday it would start up and then after a few minutes make a loud buzzing noise and then shut off. Now when I power it on it just makes the buzzing noise suggesting capacitor but...

same here.

Update. Turned out to be a broken autofill valve. I'd noticed the water levels were high for a few months but thought it was due to rain. The water was leaking out at the top of the tile (between it and the apron). Replaced the autofill valve and everything is back to normal.

I just installed a 45mph10 Stenner pump. As part of the kit I received ~20 feet of clear (opaque, actually) santoprene tubing. Since most of the tubing run is exposed to the Arizona sun for most of the day I'm wondering how well it will hold up to UV and whether I should take steps to protect it?

You may be right, Richard. At this point all I can do it monitor it. If it turns out to be something else I'll report back to the group.

I've experienced an interesting anomaly over the past few months. Back in April I did the complete measurement suite and found that my CH had plummeted to near baseline, and CYA had plummeted to <30 compared to the previous measurements in February. I immediately suspected a leak to the pool...

My experience is that you have to be very careful with CYA measurements. The test kit that the pool store uses (and that I use now) only measures up to ~100ppm; anything over that still gets reported as 100ppm. I was in the same situation last year; the pool store said my CYA was 100 but I was...

E-Konomy pool supplies in Tucson has 4 gals. 'liquid chlorine' (he said 13% but it might only be 12.5) for $13.96. Plus $6 deposit and tax.
