How is the syphon going to restart after a power outage?
The siphon will never stop, the float valve stop the water from entering the fuge, the longest power cut i've ever experienced was no longer than 5 hours (which would not be long enough to cause extreme evaporation), so although a flood would be possible, it's extremely improbable, I will use fixed platic plumbing pipe, not PVC
tubing, so it would not pop out the tank for whatever reason.
i know cutting corners here isn't the cleverest of ideas, but I have things higher up on my list of priorities.
Sometimes the LFS will have old overflows
Thanks for the suggestion, but if you mean used ones, all the LFS
I know have their tanks drilled, so are unlikely to have any.
