 Just setting up my first dosing pump but cannot seem to purge the lines of air, any tips and advice.

The dosing pump is a reefdoser if that matters.

Have you fully flushed it out? It has taken me a good couple of minutes per line to flush some units in the past

Wish I knew how to sort this,  I've used smaller tubing this time which has helped but I still get bubbles in the lines. 🤷‍♂️

I think ive sussed mine, the tubing from the containers is hard plastic much like RO tubing and is in one upto the pump, I originally had some silicone tubing splitting this, anyway the 1 piece of tubing seems to have done the trick for me.
