    Solar Heating - Adding Panels Placement Suggestions

    The panels up there do drain when the pump turns off right now (the vacuum relief seems to do it's job). It sounds like a lot of water coming down - but I don't know how much water remains in the panels. When we close the pool for the season we blow the lines to get all/most water out. There was...

    Temp Sensor Placement

    I appreciate the concern here! My first thought was to run it on it's own leg, but I was leaning towards, and you've put me over the tipping point, of instead keeping the SWG wired to the same timer as the pump, then I'll have the HA relay on that - so the relay itself will get shut down when...

    Solar Heating - Adding Panels Placement Suggestions

    Not your fault - two of my posts got merged, then unmerged, so things are a bit jumbled right now. I think Marty is going to fix it though :) Gotcha - so I should have mentioned, this is a flat roof. On the inlet side, I placed the panels on top of the stone pavers, so they are just about 2...

    Solar Heating - Adding Panels Placement Suggestions

    Thanks @needsajet, nice to meet you as well! I considered this, but I figured I could get +40sqft with the version I proposed. Having said that, it would be much easier to just add 3 of them - moving the whole rig probably won't be very fun. I'm going to have to think about this a bit more...

    Temp Sensor Placement

    I'll be honest, I've looked into the controllers a few times, but it kept not being clear what I'd really need. I can automate most things myself (and, I can't stress this part enough - I actually like this part of things, if I didn't, I wouldn't recommend it to anyone haha) - if we ever built a...

    Temp Sensor Placement

    Thanks Dirk. For some reason I didn't see your replies earlier. I was here posting and reading today (and funny enough, I was reading the other thread you linked to!) and came back to check this thread and saw your replies. When I first moved in, there was no check valve on the solar, but I...

    Solar Heating - Adding Panels Placement Suggestions

    When we bought this house, it was already plumbed for and the house had 4x 2ft x 20ft solar panels. I put them on the roof, and over-engineered things a bit so they'd stay put (courtesy of the H2T Sun Industries install examples IIRC): After a few years of this, I'm thinking I'd like to double...

    Temp Sensor Placement

    Looks like we got moved to a new thread - sorry about that mods :) Thanks, Dirk, I appreciate the feedback. I'm thinking 2 is where I'll likely go as well. I think I'll probably have it face up, just because otherwise getting to it could be a pain in that mess of pipes. I agree, I don't think...

    Temp Sensor Placement

    I'm about to do this myself - I'm curious most about the placement of the probes. I'm planning to use the tee with the 1-1/2" slip on each end and the 1/2" NPT with one of the 50mm thermowells with the DS18B20. The question is - does placement matter? Let's say you have a horizontal pipe -...

    Old Indoor Gunite / Plaster Pool - What do we do?

    After looking over the quotes now you're correct that they didn't include a full chipout. Any idea what kind of premium that normally costs over the estimates I've received?

    Salt Water Pool Indoors - Could it cause excess corrosion?

    A bunch of pictures here (pool, room, equipment, etc): pool-photos That's a good point, maybe I'm being too hard on it ;) To do a proper HVAC system would really be a tear-down situation, especially given the age of everything. The room is built of cinderblock/concrete up to the lattice, then...

    Old Indoor Gunite / Plaster Pool - What do we do?

    This is great info to have! My estimates are a bit old now (2019/2020), so I assume they're much higher now, but my quotes at the time were $15k (2 of them), and $11k. Both of these were for replastering with Quartz. As far as I can tell there are no leaks yet. I have to add water a couple...

    Old Indoor Gunite / Plaster Pool - What do we do?

    Our pool was built around 1985. I believe the plaster is original, but it is starting to chip off quite a bit. I can see some previous owners have done some patches, and we have a few sections where the plaster has flaked off, including one or two larger sections (about 6-8 inch diameter). There...

    Salt Water Pool Indoors - Could it cause excess corrosion?

    Got it. Pool was built in 1985 I believe. That makes sense. I have been meaning to install an intake fan in there to try to deal with the humidity a bit. I can't do much about MA summers though either. The room doesn't have (isn't built for) a proper indoor pool dehumidification system.

    Salt Water Pool Indoors - Could it cause excess corrosion?

    We have an indoor pool and the previous owner switched it to use an SWG (this would probably be 7-8 years ago at this point). I'm concerned that the added salt in the water (and thus salt in the air) could be causing excess corrosion of the metal parts of the room (especially things like screws...

    No pH drift this year

    We must have switched places haha... I feel like my PH this year won't stop going up, eating up dry acid.

    Pool Math - Updates?

    Thanks for the honesty @Leebo! I'm just happy to hear it hasn't been abandoned. My main feature requests are nothing too crazy. For example, with the indoor pool others on the forum have recommended different dialed in FC/CYA targets, I'd like to be able to set those so I don't have to...

    Pool Math - Updates?

    Is the app still in development? There hasn’t been an update on a year(iOS). Was hoping for a few features (previous posts on forum/via email about these). I had the subscription issue too, restoring purchase worked after I did it maybe 5 times.

    Cleaning robot for indoor pool (20k gal) with steep/rounded sides

    Thanks! Anyone seeing this in the future I also considered the Warrior SI for the Bluetooth integration, but looking at the app's ratings on the App Store - woof, that's too bad. The SI does offer the 1 and 2 hour clean times, which could be nice. Not sure it's worth $50 extra though.

    Cleaning robot for indoor pool (20k gal) with steep/rounded sides

    I don't know the technical term for the shape of our pool, but it's an L shape and the walls curve heavily into the floor. In the shallow end it's less pronounced but as the depth increases into the deep end it's more pronounced and the deep end itself is very much like a bowl. I mention all of...

    Pool Math - notes on results feature request

    It would be great if when entering in test results that were a notes field as well so that we don’t have to create two “separate entries” when really the notes are directly associated with the test results.

    Pool math - support custom ranges?

    Thanks all! @Leebo , glad to hear it's at least on the list. Good luck this year!

    Pool math - support custom ranges?

    First off, I love the app! I have an indoor pool though and some of the recommended ranges are outside where it seems to be really recommended: Chlorine too high - SWG, indoor pool It would be great if either the app had an “indoor” setting, or let us save custom ranges for each measurement...

    Chlorine too high - SWG, indoor pool

    @Flying Tivo, @ajw22 Great feedback, thanks! I was going to wait until next years opening (although an indoor pool - it's enclosure isn't ideal for winter), then as CYA drops I'll let it settle in around 30 and target 5 FC. When does CC become an issue? My CC is currently at around 0.5 (the...

    Chlorine too high - SWG, indoor pool

    Hey all (and I suppose I should at least try to page @chem geek ) 20k gal SWG, indoor pool. My last test results (TF-100): FC 12.5 CC 0.5 pH 7.2 TA 200 CH 300 CYA 65 SALT 3600 TEMP 79F With that out of the way, the FC had shot up from 5.0 to 12.5 after a few weeks of not being used, but with...
