Hi all. I got the tank overflow conundrum sorted, complete with a three way tap so I can run overflow to the gutter or to a storage bin to track to other tanks. Lotta swearing, handful of dodgy chinese parts and a lotta fun

Of course me being me I couldn't fckin stop there, and have built in a float system, so if the bin hits capacity it automatically diverts everything else to the stormwater - but I'm not too happy with the flow through the float. It's definitely limiting.

Anyone rec a wide bore low pressure float? There's like,maybe half a bar of pressure on this thing, so it really needs to be something that's gonna let everything through until it bobs up and shuts off.

current one in use
