Hi,
I reallllly don't want to post this but hey ho.
I've been offered a "choice" of valves, a Halcyon valve or a Sirtek (I think)?
Both unbalanced, which is fine for what I'll be doing
Apparently the 'H' one is "less bulky", anyone got a comment to make on which will be "best for purpose" ?
Whatever next ? DIR Pee

The mind really is boggling now !
