152mm into 150mm guttering?

[xd400]

Hello Everyone,

Changing some guttering that connects with neighbouring houses. The current one installed is half round made by Brett and states on it '152mm NOM'.

From what I see there is 150mm guttering in the market - is this okay to connect up with it or do I need to buy this 152mm stuff specifically?

Thanks

You'll find it should more or less fit. Some companies state internal sizes. If it's a tad too big you can just notch a few mm out the top of the gutter where it clips into a union. I reckon it will be the same stuff.

It's like 110mm underground drainage. It's all 4inch but it's called 110mm.
