One for the kitchen and one for the washing machine
These are pictures taken from a year ago when I was building the first version of these filters, whch I sued for testing water quality, and refining the design.
funny enough, the lot at the trailer site is covered in pure local granite gravel, which I read in koi pond articles is the perfect gravel to use at the bottom on sand filters because it has a lot of surface area for bacteria to culture on. So, I just swept some up and sifted out the big rocks.Tracy really was a huge help holding the CPVC so i could cut the short lengths.
the top baffle
Here are the baffles with the holes drilled in them. The top baffle has holes in the bottom, to the water will flow down, yeah, and the bottom baffle has holes in the sides so water will flow through and not get covered by gravel and will be less likely to get clogged.
Here is the top baffle installed in the lid, with an O ring on each side of the fitting... all it needs now is a vent hole.Here is the bottom baffle installed in the bucket with O rings of each side of the fitting.Cover the bottom baffle with gravel,fill it up the rest of the way with sand... put the lid on....
and here is the sand filter ready to be joined to the plumbing that will connect it to the drain from above and the holding tank from below.
