Filter pump clean up

Half Dome – Yosemite Musings
Hydration is the key to a safe Half Dome hike. Really. If you get dehydrated you may bonk.  The easiest and quickest way treat water is with a pump. There are about 5 different manufacturers. Your water filter pump is good for about 200 gallons. Geez, think you will ever drink that much before the plastic vaporizes? ?? If you take care of it, it will last a lonnnng time. My pump is a Katadyn Pro Hiker. Most good filter pumps today are designed to protect you against Giardia and Crytosporidium. These are the 2 most prevalent buggers in Yosemite and most USA waters. Viruses are stopped only by water “purifiers” (like the First Need brand) or UV light (like the Steripen). But viruses are rare in the United States – like polio. So most manufacturers don’t bother with the rigorous EPA testing and documentation required.  When I return home from a Yosemite trip I clean my filter per the manufacturer’s instructions.  I get a plastic milk carton, cut a hole big enough for my intake to fit in and  fill it with tap water. Then I put a tablespoon of bleach in (Clorox) and stir. I put the intake into the jug and the outlet above the water line, so I can pump the dilute solution in a circuit for about 10 minutes. The bleach will kill any hitchhiking critters you brought back. Then I take apart my filter and let it all air dry for a day or 2. If the mesh filter needs attention I softly brush it clean with a gentle toothbrush.  Assemble it all back and you’re ready to go.

    I also recommend Katadyn. I’m using the Katadyn Vario. Funny enough I bought mine in the US (like most of my outdoor stuff) because it’s cheaper than in Germany (it’s Suisse Made – so you would think it should be cheaper in Europe).

      Ah, the Euro ain`t worth what it used to.

      • Sönke Says:

        hehe, I bought my Katadyn a couple of years ago when the EUR was worth US$ 1.50+. but I also remember the time when the EUR was down to 0.85…yikes… 😉

        Katadyn Vario:

        Suggested retail US: US$ 89.95
        Suggested retail EUR: EUR 105.- (-> UD$126)

        That close to 30% difference with a weak EUR.

        Got my Katadyn Hiker FREE, also no tax and free shipping. Then I forgot to take it with on vacation
