Tetratec Deep Water 12 Airpump

[An t-iasg]

I have had this Tetratec airpump for 4 years. It's still working, but recently it has begun to make a squeaking noise, like a bird chirp. I'm pretty sure that the pump is making this noise! Has anyone else noticed anything similar? I looked for a repair kit online and only the larger Deep Water pumps have a repair kit. Another site says that this pump rarely has a diaphragm failure. Any ideas on how to fix this? The chirping is a bit annoying! The pump is run through a gang valve and it powers two sponge filters in two 5-gallon tanks. I did adjust the gang valve slightly, but the noise didn't go away, so I put the gang valve adjustment back where it was.

See if you can find the repair kit/replacement parts for it. The air filter, bellows, and some seals need to be replaced occasionally on some pumps.

Thanks...I think that's what I'll have to do. I'll call Tetra and see what they say. I could only find the repair kits for the larger models, and DrsFosterSmith, where I purchased this pump (I think!), doesn't even have this small model on their website anymore.
