Not all triacs are built the same, so maybe some particular zones don’t work well with 2 parallel valves connected to it. Does it at least work with 1 valve? If you have run out of all spare zones, you can consider buying a zone expander to give you 16 extra zones, that way you don’t have to put two valves into the same zone.
