it's a different water story, but this reminds me of how earlier in the year a bunch of kids developed liver failure from drinking alkaline water:

Yeah, it's this. Ultrapure is different from a home RO system (most of which are usually more in line with ultra or nano filtration in the typical sense) as home systems tend to remove 50-75% of impurities from what I've seen.

I'm also an engineer (unrelated field) so I decided to find some references for my assertion.

The Water Quality Association (industry group of purified water people, probably incentivized to say it's safe): Consumption of Low TDS Water

I found the WHO report that you were likely referencing: Health Risks from Drinking Demineralised Water

I'm suss of some of the studies, like morbidity of infants in the USSR. It also talks about chugging water post-exercise, and admits that regular tap water might kill you too if you do that.
.

I also found a statement from the EPA saying that they viewed consumption of RO water safe, and saying that "leaching minerals from the body" is not accepted fact. They kind have to say that, since I wonder what Navy sailors and astronauts drink.

If you took exception to me saying you could chug distilled water, alright fine that's hyperbolic and you're weird if you like the taste. Home RO systems are fine and safe as a primary drinking source.

In short, water is a land of contrasts.

Apologies if I came off as aggressive. I did specify ultrapure water - which is typically way lower TDS than what's discussed above (think <0.1ppm) while the information above is looking at say 50ppm. Orders of magnitude different. You're not going to get ultrapure water from a home RO system, but you can purchase it fairly easily (I've seen demineralized water at the grocery store claiming 1ppm TDS - it had nice big do not drink labels on it). I would absolutely avoid drinking that level of ultrapure water, which I was under the impression that you were saying was just fine.

There are a lot of potable water plants that do use RO systems - and on the ones I've done, we always monitor TDS / conductivity of the permeate to ensure that its not too low, along with selecting appropriate membranes / system design to ensure we don't actually have the ability to get to that level. But variations in source water quality can actually change enough to make it an issue - especially in places with groundwater sources that are normally very high in salt (think islands). Essentially, if your supply well in one of these locations is influenced by surface water, after massive rainstorms you can wind up in a situation where your salt content drops by a factor of 10-100, and now removing 99% puts you in dangerous territory. My experience with ultrapure comes from boiler feed systems for steam based power generation (lack of TDS in the water means less wear and tear on the turbine) and the safety information there always includes info on not to drink the ultrapure water.

This is true, and even carbon filters will remove some (not very much) fluoride.

I'd say you should also make sure that you run whatever they suggest they're going to install for you by the NSF water filter certification database. If the things you want are not listed on there I wouldn't bother/trust it.

Here's the P-550. It doesn't actually list that system as having been certified for taste/odor reduction or chlorine reduction, which I think is odd for a RO system - but ¯\_(ツ)_/¯.

Also, RO systems will waste like 4 gallons of water for every gallon you ultimately produce.

NSF is an excellent database to look at for these things. Components should also all be NSF61 rated. RO systems for home use probably waste about that much, industrial ones waste far less (but take a lot more energy / pressure as a result, and as with anything, depends on the source water).

Not as pure as you thought it was, but absolutely pure enough for whatever you're using it for camping / hiking wise. I'd want something for electrolytes if that's all I was drinking though.

The trick to getting your water to 350c is to pressurize it first! Just keep it at about 2400PSI and it should stay liquid :v:

So what brand softener and or whole house filter will be cheap and effective? I have pretty good tap water but soft water is better for my flowing locks.

Test first to get an idea of the hardness (cheap kits are on Amazon) and get an idea of your daily water usage.

I think the basic GE models you can find at L/HD work really well, considering their cost (~$500.) Size the unit based on your water use * hardness. My 40,000 grain unit works well for us with about 18 GPG hardness and around 80-90 gallons per day. It recharges about 2-3 times a month, and you can schedule the recharge for like 2AM when you're not using water.

Just figured out my girlfriends cats have been pissing in the corners of my garage for god knows how long. I figured it out when I went to pull out the large shop vac and the hose smelled like cat piss and I saw the stain on the concrete. After some searching I discovered two more places they were pissing. None of the locations show up on a blacklight, which I think is weird. Do I just have a lovely blacklight? It's definitely cat piss.

Please see the thread title. It will direct you to the knowledge that cat piss fluoresces at a different wavelength than a typical cheap blacklight.

Also, get some enzyme cleaner and spray that poo poo down ASAP.

Yeah I'm in the process of ordering some right now. I'm loving livid at her cats. They have a litter box and access to the entire backyard with lots of sandy spots and they piss in my loving garage.

e: Apparently the blacklight I own is one linked earlier in the thread as a good one, but I went ahead and bought another one with a 365nm wavelength which is supposed to better for cat piss.

My GF mostly takes care of the litter box and she says they do, but even if there wasn't any pee in the litter box, that doesn't necessarily indicate a problem because they have my entire sandy backyard to do their business in, and do frequently from what I can see. I am suggesting to her that we get a second litter box because the internet says sometimes cats don't like using other cats litter boxes. Although the times they are together in the garage is miniscule. They are frequently in and out throughout the day, and one of the cats likes to spend the night indoors with us. The other cat usually prefers to stay in the backyard but if the weathers bad he'll want in the garage, but he has the run of the place since the other cat is with us. The cat that stays inside overnight with us has not had any issues peeing in the house.

Many months ago a stray did get in the garage and peed in at least one of the spots that is being peed on now. I wonder if that is instigating her cats to mark it. I'm hoping that's the case and the enzyme cleaner takes it up enough to stop that instinct.

Aw man cat stuff is relatable content. Our 12 year old boy now has some kind of dementia where any loud noises or unfamiliar sights put him in an actual violent rage

Like, the dog will knock a glass off the counter and the noise will cause the cat to seek out the nearest person or animal and try to draw blood

How much is a new oven/range supposed to cost? Replacing our 20+ year old rental special keeps creeping to the front of my mind. It's currently gas, and I'd really like to switch it to induction. And if I can't convince the wife to do induction, then probably dual fuel, because I really want an electric oven, even if the range still has to be gas. Looking at induction, there are a couple of fridgide-aire models in the $1000-$1500 range, which seems too cheap to really be good, but then it seems to jump to over $4000 which seems like... too much. Dual Fuel seems to start in the $4000 range which again seems high. Is that what a nice oven costs these days? Are these Covid supply chain prices?

Your biggest challenge will be needing electricity. Chances are your gas stove only has a small circuit to use where electric oven will require a 50a 220v outlet.

The only thing I do know on induction is to compare the energy output of the burners.

Dual fuel is a luxury thing, you have to build basically two complete systems into a single unit then convince UL its safe. People also tend to have one or the other making them lower volume.

Lol, I knew I should have mentioned the plug.

That would be one of the changes that would need to be made, but thankfully it won't be too difficult. I actually already have the 50 amp breaker in the panel, thanks to my FIL, we just don't have it wired to anything yet. My stove location is about 25 feet, as the wire runs, from my panel. The basement is open so easy to run wire, and then just a straight shot up from there into the wall.

That Frigidaire and its siblings are the ones I've seen in the $1000-$1500 range. My local appliance place actually has one on sale for $1000 right now but I'm just going to have to let that pass me by. I think that's also the same model that's sold at Ikea. I remember reading a few months ago that the oven in that unit had some issues, but I also don't have any context for what it would be compared to my terrible oven. But looking at my local place, after the Frigidaire, things jump up to $3000 and beyond, and without any reference point, that just seems like a big jump to me.

Good to know that dual fuel is considered a "luxury" item. That was suggested by the same FIL above, since when he visited and I expressed an interest in Induction, the wife immediately balked at the idea.

I guess really, before I think too hard about any of it, I need to get a $50 induction hot plate in the effort to convince the wife.

huh funny coincidence. I'm in pretty much the same position of needing a new stove and considering induction.

Ancient gas stove stopped working, with the gas company guy giving me this look telling me that this thing has never been that safe.

I'd love to get an induction stove since it's good for the environment, and since I'm in Canada it is possible (though unlikely) that the government could actually stay true to their word (hoho) and in the near future the carbon tax could rise to such a level that I'll be saving significant monies by shifting away from gas.

I'll also need to bring in 240v to this kitchen though the panel is in the basement directly below the unfinished kitchen, so maybe not too hard. Sounds like the first step is to find an electrician and get their opinion.

As my gas stove no longer works, just this morning I dashed out and I bought a cheapo ikea single burner portable induction stove, TILLREDA (recommended on wirecutter!) to tide me over until I can get a replacement appliance. I just made soup on it and.... it sucks? Couldn't simmer worth a drat, instead doing nothing, then suddenly a bunch of soup boils up and splatters everywhere.

I'm going to presume that this $50 portable induction cooktop is not in any way representative of what I can expect if I buy a high end induction range? Anyone with experience in induction stoves please weigh in here.

What are peoples opinions on hot water heaters? We have two 50 gals in our building (5 unit coop) and one is busted, thinking of going tankless. Never have to worry about 50 gallons of hot water on our floor again (one leaked last year, another this year…), should be “unlimited” hot water, and more efficient. I don’t see the downside other than we will have to pay more up front since the warranty replacement is only $150 vs. the new tankless. I’m guessing the math for electricity will work out as money savings.

Also, despise the screw in/out valves with rubber bits, never work when I need to shutoff the water. Quarter turn always seem to work, going to specify that from now on.
