I'm resurrecting this thread because I find myself thinking about this design some.
How important is it to use clear tubing? I see a lot of DIY versions of this stirrer very often just using PVC or ABS. Is there any advantage to using clear acrylic? Is it as simple as, just for the convenience of being able to see how much kalk is left inside, to see if it's time for a refill? Or are there other advantages to being able to see inside?
If one were to build this using acrylic ... would extruded be OK or would that be subject to oxidation due to the high pH? Would a person be better off with cast? Problem with cast is it's 4x the cost..
PS. I also am a bit confused, what's all this talk about switches and mercury and elastics. ??? :? ??? Can't a person just put this kind of stirrer onto a float valve? Ie., if your sump is topped up by float valve anyways, could a person just put this mixer in between the freshwater supply and the float valve?
