Can you set it to minimum rigsby say if I only wanted to add a little if its fassa overnight. I only do next days but fassa hangs for agesThe doser is good and it will give you peace of mind. My Ritmo and water pump needed expensive repairs after using Wickes and not flushing out.
But I did continue using accelerator mainly an Irish one what didn’t ha the Chloride free additive in.
I took the pipe off the mixing chamber, wacked up the float to maximum and took out the mixing shaft then ran it for a couple of minutes on speed 10. Not had a problem for 4 years after the repair and I used Accelerator all year round except for overnighters.
