Fernox TF1 drain valve won’t open

[Stuart Toal]

hi chaps, anyone had an issue with the fernox TF1 bottom drain valve ? Just gone to drain it for the 2nd time and it’s not opening fully - just getting a small drip. The spindle that you turn with the plastic cap just spins and spins, it doesn’t feel like it’s doing anything internally.
It’s only been on the system for 3 weeks...

Its blocked with sludge, sometimes a small screwdriver into the hole over a bucket or tub and rattle it around might clear it, or you may have to remove the filter and give it a blast through a tap.

Is it the omega of the older black plastic one

does the spindle move as sometimes the cap / key rounds out?

Most likely partially blocked.
I just remove the lid (valves off first) and poke down through the valve with a screwdriver or piece of wire to start it flowing into a bucket

New big o-ring needed after the lid comes off
