screen warning pipe elbow

[8aviashusband]

Whilst trying to locate a new lid for an old CW tank, I encountered "screen warning pipe elbow" as part of a kit of bits for installing a F&E tank.
Please can someone tell me what a "screen warning pipe elbow" is, what its for etc. Something to do with Bylaw 32?
Please excuse the ignorance.

I suspect that you are looking for the elbow shown in the picture in this link

I think it's bylaw 30. The screen inside the elbow is to prevent insects crawling up the overflow pipe and setting up home in the tank.

I've never heard of a bylaw kit for an f&e cistern, only for the main cold water storage. I'm happy to be educated though

Thanks gents.
Yes, newboy, this looks right, and moggett, you've answered my question.
I suspect I confused where the overflow kit would be used, since I was looking for a cover for an F&E tank, and stumbled upon this screen warning item in the process. Just wondered what it did.
