Photox dev tank pressure release valve
Is anyone aware of a way to repair the pressure release valves on the blue Photax 35mm/120 "universal" dev tanks?
I've got two of them (second hand) and both of them have broken valves (the three plastic tines have broken away). Unfortunately this means they leak like crazy when agitated - there's nothing to push the plastic button against the rubber cap, thus there's no watertight seal.
Failing that -- a source of spare lids and/or valves would be an acceptable alternative
