hi guys, not been here for a long time. anyway, the past week my waterpump started giving my trouble- it makes nasty vibrating noises, that dont go away when the pump is not touching anything. last night i dismantled it out of the PC and cleaned it up, put it back in and the noise is twice as bad can anyone enlighten me as to what i can do to sort it? i know these pumps are supposed to last forever. BTW its the smallest model that Eheim do i think. i bought it as new (done no work) and have ran it on my PC for 1/2 to one year. thanks in advance?
