my t90 si used to drip constantly when powered off, i changed the solanoid valve, (cost me 25 euro. i got mine from a shop that ordered it from ?i dont no?, but u can get it from maynooth, kildare. i got fone number somewere if u need it). its very easy change part, just make sure u turn off electric power trip 1st. part is like a stop cok or tap that turns on the water, yours is not turning/shuting off,making it drip. the part is next to the filter (right side), 2 little wires,. (u is t90 si pump ?)
