Exactly the info I was looking for. Tonight my toilet was jetting water all over the place out of the top of the ballcock assembly so now I've got some ideas of what might have gone wrong!

This helped me a lot and resolved the puzzle for me really well. The red washer is not the critical part, but making sure the ballcock washer is thick enough and no hole, grind down the water “hole” of there is any crack. Thanks again!

Went to change the washer because it takes 15min for the cistern to fill, but the nut was locked solid. I was twisting the riser pipe so much I thought I better grab it at the float pivot, and naturally the pivot snaps off because it's brittle. Typically there is no inlet systems at my Bunnings so I had to make a temp steel bracket. What a PITA.

Thanks. My cap was on very tight and felt like I was going to break something. This showed that at least I was on the right track. Go it off in the end.

Good job. My Caroma Uniset cistern had the same crack on the inlet jet, and the ongoing hissing. A bit of sand paper took it down about 1.5mm and it seals perfectly.

Great hack on the little crack in the riser pipe. Would've missed it without your alert. Ground it down and all is good. Thank you.

Thanks my inlets had same split .

Good on ya man, Exactly what I needed to know. And yeah the top cap was a ba$tard to crack!

Cracked inlet... Many thanks for the idea.. couldn't work out why it wouldn't seal.

Great to see I have helped in some way.
