My fairly ancient cistern seems to have failed - it only flushes when the water level is dangerously high. This is a low-leve cistern, sitting on the toilet bowl.
I was wondering if there are any clever units now which one can use as replacements? (I don't really want to replace the whole unit.)
I'm thinking of something that has 2 (or more) levels of flushing, to save water.
Also, can anyone point to simple d-i-y instructions for replacing the inside unit?
