    My new automation system.

    Hi! Glad my youtube was informative. I really should find some time for updates. 1. The reason why I went with the MCBs is I wanted to mimic as much of the current boxes existing characteristics because I know literally nothing about electrical codes. I figured by copying what was already in...

    SPA return check valve breaks. Want to nix it. Thoughts?

    I take it back. It's not cracked the leak is just more noticeable now. When I first bought the house in 2018 the check valve was visibly cracked in the site glass and housing and leaking bad. I called a pool pro and had it replaced. Post-fix from day 1 there was always water pooling at the...

    Call for collaboration

    Most people around here, myself included pre-SWG days, use a Stenner peristaltic pump. It keeps the chlorine in an non reactive UV protected hose and can be controlled via automation or on a built in timer, depending on model. The output just goes into a tee into the plumbing and holds up very...

    Call for collaboration

    I think the consensus here seems to be that ORP isn't a reliable indicator of Chlorine levels in the presence of CYA. That could be a problem. The rest looks cool though! You could also add a water level sensor. When I was doing my DIY controller I remember reading a thread about a few...

    pH sensors that don't have to be calibrated

    We found a device for $2. It took 6 weeks to get here, but it was $2. All the other options we found were $40 minimum. Here's the link: 4-20ma to voltage converter

    Does anyone know of a wifi-enabled filter pressure gauge?

    My DIY controller reads a pressure transducer hooked to my filter It's not wireless though. You could do something like that though. If you're handy, here's the parts to make one. Raspberry Pi Zero WH - $36.49 (you can hunt around online and they're like $15)...

    Unorthodox pool chemical automation

    I'm in the *very* early stages of doing this myself. I bought every single chip (yes, that's three different links!) for monitoring RGB levels but I settled on a EZO-RGB when I realized I didn't want to solder. I picked up a DPD doser thinking I could use a solenoid to push the button and drop...

    Pentair IntelliCenter Review and Information

    It's funny your speaking in network terms. When I saw it on the RS-485 sniff I instantly thought it looked like a DHCP request. What about the 10000 monkeys with typewriters writes Shakespeare approach? What if there was program that has a few formats we suspect it might be and recursively go...

    Charcoal Chunks Coming Out Of Returns?

    From the article, not a dig, it's buried in there: "The simple solution to solve this problem is to find another less noble metal to use as a sacrificial anode that corrodes but doesn’t cause staining " Here's one on Amazon. Link Do NOT just throw a Zinc ring in your skimmer. It does nothing...
