Find that when empting shower tray on B32, it seems to leave about 8mm in tray (wet room) which pump refuses to suck. Checked and cleaned filter but problem repeats. Means a sponge for a few minutes into basin. Anyone else have same problem? 😡
You’re discovering the foibles of the B32!! It’s a known problem: the shower drain is in the wrong place so you have to become adept with a sponge. Not a lot you can do about it, I’m afraid.
