McAlpine T28M-NRV 40mm Non-Return Valve White
Looked at several non return valves. And this one fits the bill. Good well made product.
No smells come out and waste does not come back up to the shower outlet.

Solves all sorts of back flow problems in bathrooms, and is easy to install. A tad pricey, but works fine.
