Hello,
Has anyone had any experience of these?
I've a vertical one in my towel radiator. It's the highest rad. in the system so it collects all the air. The valve will not self-bleed nor will it bleed manually but if I unscrew it with a spanner it bleeds then ;)
I've got a few horizontal ones in other rads. they fit new rads perfectly but it's a struggle to get them all the way into old rads and I have been scared to force them. Am I best leaving them half sticking out? They are watertight. It's just they don't look very pretty like this.
Thanks.
