Problems with Tetra Whisper Pump

[guns286]

Hi, I have a Tetra Whisper 100, duel outlet, air pump for my 72g FW tank. I've had it for 2 months and everything has beed great. But, a couple of days ago I started hearing a loud buzzing comming from the pump. I checked the filter and both air hoses but noticed no problems. Then yesterday I saw that the left outlet was pumping alot less air out. This leads me to believe that there is something wrong with that outlet and that is whats causing the noise. Has this ever happened to anyone? And, if so, is there a way I can fix it, or do I have to buy a new one?
Thanks
Bill

Thanks anyway folks but I figured it out. I opened up the pump and after figuring out how it workes I realized that both rubber diaphrams had a rip in them. Luckily I did'nt throw out my old pump, which had a blown motor, so I pilfered the diaphrams from that and installed them in the new one. Worked perfectly.
