I'm glad it went well for you. But I run a not-for-profit pinball museum, and I have specifically had to ban volunteer repairpeople from using the chatbots because it will confidently propose idiotically wrong solutions. Which will then get proposed to me, or just directly applied, with equal confidence. At this point I'd rather hear, "My horoscope said..." than "ChatGPT said..."

I expect that it's good for common use cases that's well documented. But then, so are a lot of other approaches.

Yeah, I would imagine pinball machines are at least an order of magnitude more complicated to maintain than above-ground pools are. That situation sounds really annoying, I feel for you.

I find it telling that the highest praise for LLMs comes from people using it for something where they admittedly have very little domain knowledge. Domain experts usually mention major caveats. I've been testing them on subjects where I already understand the problem well, and I've yet to see any outputs that would make me trust them on things I don't already know.

That's a good point - I've heard people make the same one whenever LLMs are brought up. I hope someday you're able to get more value from them.

Anyway, my pool's looking great and I gained some new skills. I probably could have gotten there with books and YouTube alone, but having another tool at my disposal made me a bit more confident.

It’s likely it missed some crucial subtlety that will come to bite you in the ass down the line.

That’s the thing with AI - its responses sound plausible enough to non-experts but time and time again I see experts in any given field being able to identify AI content by pinpointing subtle but crucial errors. That’s one of its dangers - it gives you enough confidence to shoot yourself in the foot.

Maybe, but that's part of the experience of learning. I plan to maintain pools for the rest of my life, if I made an oversight which costs me down the line then the lesson will be that much more memorable.

This is an above-ground pool with a pump and a filter, the stakes are relatively low. In the absolute worst case I could rip it all out and pay a pro to do it for the price I was quoted.

reply
If that's a pool for human use, the worst case is a bacterial/fungal infection due to incorrect filtering.
reply
A pool filter is for removing physical debris, it's not really for preventing bacterial or fungal infections.

I guess what you're talking about is sanitizer, in my case we use chlorine. I test it every time we swim, but I wouldn't have needed an LLM for that. It's very straight forward to maintain pool chlorine, my Dad taught me that when I was 13.

Human workers also wreck these jobs horribly that come to bite your ass in the end. I think an intelligent person equipped with AI and common sense and real stake in the thing being well done (because it's their own, so they care) is better than whatever is possible to pay for or book in a realistic timeline from another human.

Also, ask people in the trades to review each other's jobs. They will harshly criticize each other too for missing basic things and then go on to vehemently disagree. As an outsider it doesn't mean much that an expert found some fault. They always find something to nitpick.

reply
> Human workers also wreck these jobs horribly

Yes, but with a human worker there is a chain of accountability. With AI, there is none.

Have you had an argument or dispute with a contractor before? It's better to just do it yourself when you can, and fix it when it breaks

In the 90s and prior you could have done the same thing using the public library.
reply
Still can (libraries still exist plus the internet) but finding the online resources gets more and more difficult; the fact the author mentioned youtube videos instead of someone's old-internet style "all about pvc pipes" website [0] or comic sans plumber sites [1] is already telling.

I feel like if you had wanted to you could have done it before. When I got a pool in 2020,there were still old school phpBB forums out there dedicated to DIY and maintenance. That same summer, my neighbour who in no way is techie or handy redid his plumbing too.
reply
I've love to know more about how you did this. Was it the underground plumbing or your pump system above ground. This is one of the few areas of the home I have little understanding of.
reply
This was for a largish (40,000L) above-ground pool with no hookup to my home's plumbing system. The water was all pumped in from a water truck.

The previous system was also installed by a non-professional and was mostly tubes. It leaked to all hell and looked generally redneck and awful.

First step was draining the pool and doing a nice deep clean. Then I ripped out all the original plumbing until it was just the pool outlets, pump, and filter.

I arranged it all and measured the dimensions. I fed the figures along with a tonne of photos and explanation to GPT. I spent a while talking pros/cons and landed on a design which lined up with what I'd seen on YouTube. I had it prepare me a full shopping list of PVC, tools, cements, etc. all linked to a local pool dealer. I picked it up the next day.

The PVC was all cut with a chop-saw then primed and cemented together. I found this part easier than I would have expected. I put a layer of TigerFlex hose between the PVC manifold and the pump/pool/filter inlets so it had some tolerance.

We've been swimming in it all summer, no issues whatsoever so far.

I hope what you’ll discover to be wrong needs only $5000 of repairs.

I hope your DIY projects go well and you don't need any repairs at all.

Fellow pool owner who has always drawn the line at “only pros do the pvc cutting”. I’d love to hear more.
