Does this product "https://www.bunnings.com.au/evekare-15-x-15mm-chrome-double-mini-cistern-stop-tap_p0666242" include a non return valve as part of the product.
Hello @Getricks
The evekare 15 x 15mm Chrome Double Mini Cistern Stop Tap does not come with a built-in non-return valve. You'll need to install either the Kinetic Backflow Preventer or the evekare Smart Bidet Replacement Dual Check Valve.
If you need further assistance, please let us know.
