I have just fitted a triton thermostatic mixer bar run from a pump. Fitted S flange, cold feed from tank in attic etc. Plenty of flow from hot and cold without bar fitted, but as soon as I fit bar, no hot water. Temperature control turned up fully.
Any suggestions anyone please....

Hi, I too have exactly the same problem and have been advised that it's because the pressures aren't balanced. If you do find out I'd also like to know.
Thanks and good luck..
