After a busy few days with thirsty visitors and an Isomac that doesnt have a separate lid on the tank...i got fed up with taking all the cups etc off the top to refil the tank every other day...
Soooo...idle time and active brain combined to improvise a "auto refil" for the trusty Isomac.
A minature ( 1/4 " ) flost valve ..as used for fish tanks.... and a meter or less of 6mm nylon tube were obtained, and the idle hands stirred into action .
A small "L" bracket was fabbed from perspex to mount the float valve in the top of the tank, and the tube was threaded out to the bottom of the machine.
Originally i planned to simply connect this into the outlet side of the drinking water filter under the bench,..which is plumbed with the same 6mm nylon fittings,...but an imminent house move led me to simply keep the feed pipe on the worktop (tucked under the Isomac) and pull it out to connect it to the drinking water faucet when i want to refill. A simple rubber push on connects to the 8mm faucet tap.
Now when Isomac need a refill... ( i usually just wait til the tank kicks the stop switch) i slip the pipe out from under the base, push it onto the faucet and hold the push tap on until the flow stops ( 3 mins ,..empty to full)..
Sooo much easier, no need to mess with the cup warmer tray etc.
When we have relocated, i will connect this up permanently .
total cost ..under $10
This type of valve...
