Convergence issues with my k-w model

i've been using k-w sst model cause there´re separated flow in the chamber and downstream of it. I'm using y+~1 in my model but i can't achieve a residuals lower than 10-3. the inlet mass flow is around 419 kg/s of water and the pressure outlet 3e6 Pa. How you can see in the image i´m using tetraedrons cells and sweep some zones to reduce the CPU cost. pd: This is a pressure reducier system. i´m waiting for your help, Saludos.
