hello.
I had installed a waterfall mixer tap in my bathroom and for the first year all was working well with good pressure

depending on the lever position (left for hot and right for cold) i was able to mix the water but now positioning that lever has no effect and i am always getting cold water.
this can happen any time of day and could last from mins to hours.
is my tap faulty and do i need to replace any part in it
many thanks for your help.
(my knowledge on tap mixer / tap parts = 0)
