The valve should open fully but it is a gate valve- notorious fo
jamming due to build-up with crud.

Notorious for being a pain in the bum, poxy, spawn of satan, useless
piggin objects :-(



I'm also having issues with "service" valves recently. 2 have started
weaping past the valve stem such that drops of water appear on top of the
slotted screw-head type closure thingy. FWIW, I have a similar problem with
the 90 degree special valves supplied with the Magna Clean filter in the CH
system .
