Here is another reference on gravity flow water systems, includes information on hydraulic ram pumps.

Would one of the larger Lifestraw filters work for filtering pool water?

Like this.... https://www.lifestraw.com/products/lifestraw-flex-multi-use-water-filter-with-gravity-bag

No, Lifestraws don't remove dissolved chemicals. They're mechanical filters.

Absolutely will work.

If your pool has sat in the sun for extended period of time, ok, maybe. In my experience, the Lifestraws, like the Sawyers, do not remove dissolved substances. You run tannin rich bog water through either, while safe to drink, will still come out looking like iced tea.

Pool shock, flocc, algicidal chems, piss (urea), etc do not get filtered out. Not sure if i'd want to drink that.

Where are you getting your information from?

I thought they were mechanical filters too. Thanks Squaregrouper! I learned something new today

Apologizes.

Wasn't even aware that Lifestraw came out with the "flex" line with the carbon filters. My experience is with the standard models (where only the stainless straw had an activated carbon module).

Squaregrouper is correct....will probably work.

Alan3413 · Sep 20, 2020

Did a little more digging.

So the answer is: it depends

The original model (the one I have) doesn't work for chemicals

Will have to look at upgrading the family filter I bought a couple years back....doesn't have a chemical filtration capability.

Think a Brita jug filter will fix that after it's gone through mechanical filtration

I will dig up a DIY carbon filter I made out of PVC and post a picture. It is a pretty simple concept based on forced dwell time.

Thanks for the info! Not that I would need it, but it’s a nice 8000 gallon reserve.

Good question... Boiling kills things. The other issue is toxins in the water which aren't alive.

Like endotoxins? I believe they are only relevant if you are using the water for injection (WFI).

Anyone made a well dip tube/bucket? We lost power for two days with the snow on Halloween 5 years back or so. What a PITA is was as we had kids over and the girls flushed the toilets right out of water.

+1 on how that went and what parts were used.

Bonus - are those Berkey or Alexapure systems worth it?

Would an old school pump spigot work?

Jesus, I was thinking a piece of 3" PVC with a cap with a rubber flapper valve and a 100' drop line. Not a $700 water pump. :shocked4:

no those kind of pumps will not work as the line will collapse under the suction. The plastic line works with the submersible pump as it pressurizes it and the hand up at the top depressurizes it.

thinking like this. wanted to see if anyone tried it.
