Thanks for your insight. I guess I didn't mean to imply that the ORP sensor did "nothing". But I was looking for something that would tell me if my FC was 6 or 9, and I struggled with getting that level of output. I'm happy to try using different software to read the probes, but I was just...

Can you post how you did this in case it happens to others?

I waited to backwash until my flow started dropping off (it was easy to see the skimmers weren't working well anymore). That said, this corresponded to between 25% and 50% increase, so the rule of thumb seems to work. I will note that my days of having to do this every 30 days also...

I went down the Atlas Scientific ORP, pH and temp probe path a couple years ago. Spent $$ for a system that essentially ended up being a clock (periodic drift during the day/night). And that's for readings in the "shade" under my opaque Autocover, using isolated supplies and isolated I2C. My...

I ended up coating the new part with CRC Marine Heavy Duty Corrosion Inhibitor. Not sure how effective it will be since I had to press it back into the bottom of the filter, which may have rubbed off some of the coating. I probably only have to clean my filter once a season, so I'll look at...

All fixed. I ended up getting the "Swimables" brand replacements from Amazon since they would arrive here the fastest and I was worried about the freeze coming Wednesday night: Amazon.com: Swimables SuperFlo & SuperFlo VS Pool and Spa Pump Replacement Unions - Replacement for Pentair 350157 -...

I guess we'll see how the inyopools part works. Can't be worse than the Pentair part that broke after 1 year... I think I can just cut flush against the elbow and then put a coupler and a "street" 90. I actually have those parts in sch 40 already and it seems pretty close. My main concern is...

Started up and there was a trickle of water. Tightened with a rubber strap and... snap. One year old. I see that inyopools seems to carry an alternate brand? Custom Molded Products Union Kit for Pentair SuperFlo - 350157 - INYOPools.com Or I can get the Pentair one. My bigger issue is that...

I had the same debate with myself when I got my SWG. I have a 23k gallon pool was was deciding between the RJ45+ and the RJ60+. In the end, I went with the RJ60+. Because I generally leave the autocover closed when we aren't using the pool, my chlorine use is very low. Luckily, the RJ+ series...

I replaced my old Pentair DE filter with a Pentair CCP520 (quad, not DE) cartridge filter last year and it was excellent. I can easily go the whole season without cleaning the filters (partly because of my autocover) and the pressure was very low (excellent flow). No DE to buy or mess with...

I think it is more of a design flaw than a manufacturing defect. Mine was rusting from the crimps and welds. Looks like the same thing for you. Will it completely rust away. Probably not? I'm not even 100% sure what purpose this piece has since there is a steel band right on the outside...

Circling back around to this. The MechEs are still debating. They actually seem to like powder coating over passivating. One of them suggested this: CRC 06026 Heavy Duty Corrosion Inhibitor. It certainly seems like it would work to prevent corosion, but I guess I'd be worried that it would...

+1. Find out what your City/Town requires. Mine follows the the 2009 IRC (Appendix G), but yours could be different.

I love my autocover. I've written about it a bunch on here :p It makes me feel good from a safety perspective. It keeps the UV off the pool. It keeps debris out of the pool. It helps control the pH. It even heats the pool slightly.

+1 to these. We just went through this because it turned out that the pool that was built 8 years (!!) before we bought the house never closed out their building permits, so we had to have final inspections on the pool (luckily, the plumbing and bonding had been done). Current code for your...

Pentair did agree to send out a replacement ring after getting my serial number and proof of purchase (inyopools). Tracking number says arriving tomorrow. My MechE friends are currently debating passivating vs just powder-coating the ring. I'll report back on what I decide to do and what the...

After consulting with my MechE coworkers, I'm probably going to ignore it for now other than trying to get a new one for free from Pentair. According to the MechEs, the correct thing to do is to passivate the the SS ring after manufacturing. This will probably cost me $50-$75 and should be done...

Any worry the coating will end up in the water?

Er, I guess I assumed it would come out based on it having its own orderable part number and no actual fasteners... At any rate, I went around a bunch of times wiggling it with a screw driver and it worked its way up. Took about 10 minutes -- I was trying to be careful. As far as I can tell...

The points that it is rusting from actually appear in the drawing in the manual. So they seem to be actual features, not just artifacts of manufacturing...

Here are some more photos with the ring out. seems to be rusting from a specific few spots. Maybe where it was crimped/damaged? Is this crappy SS coated in something?
