auto topup

Hmm....

i think the first 2 design cannot ... risky isn't it..?? but 3rd design with the 2 tubes to the air-tight bottle can work ... but must make sure that the bottle is really airtight... if not the water will slowly leak into the tank.... then before u noe it ...

i made a drip auto top up a few year back... same concept... but different design ..

for those who are thinking of making this... i'd attached a drawing with instructions.

hey!! btw... i'm a guy with too much brain-juice to waste .. hehe

if anyone of u got any DIY ideas but cannot put to realism, try emailing me... let me waste some of my brain-juices for u... as i got a thing for DIY projects ... "occupational hazzard" (design engineer)

enjoy "DIY"ing...

oh yah .. btw ... the holes at the tip... dun make it too big .. start with a small hole ... test it .. if not good enough.. then enlarge it .

wow..but my sump will look more like a toilet system with that floating thingy..... (refering to the link pics)

opps..!! sorry sunny!! .. i would not want that toilet thingy in my tank as well... hehe .. i was actually refering to this ..

I tried this before it works perfectly BUT ONLY and ONLY if the container u have is rigid.

Otherwise, it would simply deform and deform spewing out water non-stop.... also, to DIY, the air-tightness is crucial...

In the end I gave up and when with my DIY tubby...

the output water tube has to be in 'U' shape below at the end?

I believe this design will work perfectly well! It is the same as the nurce top off system. However, I think the company has stopped production.
