answer 1
The Sawyer filter comes with a syringe which you use to back flush the filter, as often as you need or want to. So simple a child could do it with ease.

If you want to use exceptionally dirty water. I suggest you prefilter the water through a t-shirt or some cloth.

answer 2
Per Sawyer web site: "The Sawyer Water Filter has a lifetime limited warranty against defects in workmanship. Should this product fail due to failure in workmanship, return it to one of our authorized repair facilities."

Even with very high particulate /turbid water you should get 5 to 10 gallons through the filter. The Filter's flow will start to slow down after use; this is normal. The quality of the water will greatly determine when this will happen. To extend the life of the Filter, periodical back washing is REQUIRED.
