Maintenance

There are some maintenance tasks you'll need to carry out in order to keep your

SWS-200 solar water still performing optimally. Here are the tasks, ordered from

most to least frequent:

Cleaning the glass pane

The outside surface of the glass pane of the still will accumulate dirt and bug/bird

droppings over time. Clean it in the same way you clean your house or car

windows. For a streak-free window, as a final step try using a microfiber cloth

such as "E-Cloth" with distilled water.

Replacing the GAC

The GAC (granular activated carbon) in the post-filter periodically must be

replaced, especially if you begin to notice a slight taste to the distilled water. The

best GAC to use for filtering small organic volatiles is made from coconut husk.

Inexpensive bags of coconut husk GAC can be ordered online, for example

through Amazon.

The post-filter is easily removed from the barb fittings on either side. Shake out

the old GAC (can go on compost pile), and pour in new material. Note there are

mesh screens on either side to contain the GAC. Put enough GAC in to allow for a

tight fit. Pour some water through before closing it up, to ensure all the carbon

grains are wetted and to wash out any small grains. The two barbs on either side

should be pushed in firmly, so the GAC is well-packed in the tube.

Cleaning the wick

Over time, depending on the mineral content of the source water, the wick will

calcify and accumulate other sediment build-up. This degrades the performance,

because such sediment is less solar absorptive than a clean black wick.

To clean the wick, first turn off the water mains faucet. Next, cut the 1/4" drip

irrigation tubing near the main valve of the still. Try to make a clean cut, because

you'll later re-attach the tubing to the barb of the valve. Remove the small piece of
