Like the illusion of Wall Street, with its vast and powerful investment banks, now shuttered, China too is an illusion perpetuated by the Globalists that gave us the 15,000 mile Caesar salad, poisoned cat food and lead based paint on babies' pacifiers. Like the illusion that money would come from thin air to always push housing prices higher, China has spent a generation pursuing its illusion. Pursuing an unattainable dream to be like the West, while 6000 years of its carefully shepherded top soil blows into the sea.

Just saying it would be simpler.

Doesn't drinking distilled water have a negative effect on the human body over time?

Just wondering.


What energy source would one use to boil water? It takes a lot of energy to boil water, and my goal is to use less energy (electricity). (I do not have natural gas, propane, or fuel oil at my house. And I'm not going to fire up my woodstove in summer just to boil water, lol!)

There's a link I posted in the Solar Distillation thread to an article that states that most minerals we get from foods, not water. Fluoride is usually in your toothpaste (as NaF).

I take multi vitamins too.

And, most of the time I use the distilled water for coffee, tea, Gatorade mix, juices, soups, etc. Once you use the distilled water for anything like that, it's no longer distilled.

Maybe virgin rainwater, but once it's dripped down your roof it surely picks up a lot of contaminants. I know in areas that don't get much rain like Los Angeles, once it hits a dry surface the rain turns into a virtual mud with all of the car exhaust particles it picks up.


Currently while electricity is still available, and as I stated in the OP, I'm filtering the rainwater through a 5 micron sediment filter, a 3 micron carbon filter and irradiating the water with UV light. This water is fit to drink, but I take it one step further by distilling it.

Particulates such as dust, soot, leaves, rust, metal particles, salts, bacteria, pollen, bird feces, bugs, etc. do not evaporate. It's the evaporated water that is recondensed and collected--the definition of "simple" [as opposed to "fractional"] distillation.

Well if I had to I'd boil it over an open fire. It doesn't take that much energy to bring a pot of water to boil for 5 minutes.

PostPosted: Sat May 03, 2008 12:22 am    Post subject: Converting steel drum to a rain barrell? Add User to Ignore List Reply with quote

Does anyone have any tips on how to install a tap into a steel drum, so that it would have full, non-leaking seal?

All I can seem to find on the web is info on converting food-grade barrels, which is a bit different than doing it to a steel drum.


Thanks in advance,
Legless.

I haven't done it so take what I have to say for whatever it is worth. this is how I would try the first time.

Get a tap and die set at the local hardware store. Drill a hole in the barrel one size smaller than your spout. Tap it out.

Get a tube of silicon. Lather the spout amply and screw it in. Place additional silicon on the inside of the barrel.

Let it dry, try it out.


As an aside, why are you using a steel drum? Did it have anything in it before?

I've located a source of steel drums in my hood, cheep. The previously held packages of PVA glue (White bookbinding glue). The interior of the barrel looks and smells clean.

I think you can get taps that are intended to go in plastic tanks that use a rubber gasket on both the inside and outside, and they thread in to a big nut on the inside. You might check with an RV supply house.

Also, the aluminum drip pan under my water heater has a pretty standard looking combination of a PVC pipe stuck into the side of it that is slip-fit on one end, threaded on the other end, then two rubber washers as above, and large plastic nut. I don't know where it came from but it looks like it might be what you are looking for. You can add a valve downstream from that. It might be a standard plumbing part.

try a lavatory drain in the flat bottom.
cut a hole, install the drain as you would a sink
once in place, its a matter of plumbing parts after that

If the barrel has a head in it, that is, a non-removable lid, it will have 2 holes, one to fit a 2" pipe thread and the other to fit a 3/4" pipe thread. Some removable lids have this also, but most don't.

Since you can see inside? I think you have a removable lid, probably with a locking ring. Tapping the side will work, but you only get one thread, so you are depending on the silicone to seal it. Another answere is a "bulkhead" fitting, similiar to a bolt, with a washer style gasket. It has a pipe thread on one end. Available in PVC from Mcmaster-Carr in Chicago. They take Mastercard/Visa, and ship on the brown truck. The female 1/2" pipe thread size part number is 36895K121. About $12-$15, and any standard 1/2" threaded valve will screw right into it. Order online at:

www.mcmaster.com

Phone in order: (330) 995-5500

Old reliable industrial firm, reasonable prices, and great service. No minimum order. I buy regularly from them for both personal and business uses. They don't want to give out paper catalogs, since they are costly. My old one is 3392 PAGES! This is the Sears and Roebuck of the industrial world. Easy online search, for all that rare hardware stuff. HINT: The key to finding stuff is knowing the correct name for it.

edit: Tried to make alink to the page, but it won't work. Just enter the part number in the search block, and hit go. Has pictures, too.

This fitting requires a 1 3/8" dia. hole to install. Get a hole saw for your electric drill that size, and run it SLOW rpm, or it will over heat and die young. go slow. Works good.

wouldn't it be better to use stainless steel ?
(rust and such)

seeing as rain is getting more acidic every year ?

Ok, sorry if I missed this somewhere.

Question on Rainwater Collection, I assume the best way/easiest way is to use my exsisting roof to collect rainwater...?

If I installed a gutter, wow the water I could collect!

Possible problem...? Shingled roof??? I need some help on this one, they are asphault shingles. Probably not good for drinking Smile, anyway, cheap and easy to take out the bad stuff, or is that impossible with dealing with a shingle roof?

Ok, got that one out of the way, now, I assume, I can use the rainwater collected from my roof to:
Flush Toilets

What else? Water Crops/Foodsource, or will this posion my crops?

This is a tough one, would appreciate any help on this one I could get. Seems like the easiest and just need a gutter and ready to go, large surface area, larger than any tarp or other setup that I could setup, without taking up precise space on our limited 2 acres.

But do not want to posion us directly or indirectly.

Thanks Again!

Of course, a metal roof is best. (When this house lost some shingles during a bad storm, insurance covered the replacement of the shingles, but I went ahead and spent some of my own money and got metal installed.) If you want to collect water off of a shingle roof, and use the water for drinking, then using activated carbon filters will remove most of the organics (including polyaromatic hydrocarbons [PAHs]- the principle organics coming from the tar adhesive.) Don't forget that most people ingest quite a few
PAHs from eating barbeque.

What I would recommend is to take a rainwater sample collected off your shingled roof to your local health department and get it tested for PAHs and Total Organic Carbon (TOC.) Once you know the concentration of PAHs then you can determine how large a carbon filter you would need.

Thanks for the info on shingled roof. I have been checking in all day waiting for the answer too. The End Times Report has a nice section on rain water collection for more information. I became a serious fan of metal roofs after living in SW Florida and watching our roof hold up during the hurricanes. Unfortunately since we moved to TN we have a home with shingles.
