Dirk: thanks very much for the update. I'll take a look and consider adding the red wire bypass to the existing black. for the record, my interaction with Pentair support suggested they are aware of this weak point (susceptibility of the connectors to corrosion and burnout). The argument...

Haha, Time marches on...I saw @bertschb thread after I posted. Very cool. Have to take another look and consider the "pre-fix". Thanks again. Ed

I am reporting in that this repair has held up for 17 months. So worth the effort. Hopefully won't jinx myself by this report! Thanks to all, especially @Dirk for prior posts and help. Enjoy the 4th!

thank you both for the helpful replies--food for thought. Putting the two suggestions together, I have an idea--test whether my pool water interferes with dilute Cl freshly prepared and detectable in tap water alone. I expect it will, and trying different ratios of pool to tap water (keeping Cl...

After several years relying completely on a salt water generator for chlorine, no contamination events requiring slam, and reliable measurement using FAS-DPD, i now have a 10 month issue of being unable to measure Cl. Initially i thought it was interference from components of a stain removal...

OnB: thanks for your reply. I had read the Ca Nodules thread (and many others) and share the concern, but based on past PB responses and the language of the warranty (good topic for another thread: "what to look for and require in a PB contract!!") seems to favor the builder (IANAL), i.e...

OK here are current chem stats and a couple pics, although i find it hard to photograph well without a manual focus... pH 7.3 lowered a bit for current campaign, usually runs 7.5-7.6 Ca 375 NaCl 2900 (its been raining) Alk 80 Cya 70 Cl 4 CSI =-0.41 first is a couple years ago when i did a...

My pool surface has always had white chalky staining, so much of it that it wasn't clear what the true quartz french grey color was supposed to look like for the first 2 years of ownership. The pool was put in as part of a new home build, and there were too many issues to deal with in parallel...

Dirk: more or less my thoughts. Would add: burn may not be related to the current per se, but due to corrosion of the wire pressure contacts in the connector, which just isnt up to the outdoor location and frequent on/off cycles. Corrosion causes resistance causes heat at the rated current...
