some one asked me to post this
it should cost around $15 (less the tool cost)
all the sizes are the sizes I used for mine but you can change the sizes to anything you want as long as you don't change the basic lay out (or it will not work)
my sizes will put the water level just above the black (or brown) plastic lip on an AGA
To adjust the water level down you need to shorten G and H
To adjust the water level up you need to lengthen G and H
(just do not put the cross above D and K)
COMPLETED
