Air pump problems

[dickydoo]

Hi, I have a Precision SR 7500 aquarium air pump.At the moment there is only
a slight amount of air comming out on either side.The motor runs on hi and
low and this works okay. I took the bottom of and there seems to be only a
small amout of vibration on the diagphrams. Can anyone point me to a web
site or tell me how to repair. Thanks.

you should be able to go to the store where you bought it or to any LFS and
purchase a replacemnt diaphram for the unit. I'm not familiar with this
particular pump however have changed many in Optima and similar pumps.

Is that the problem ? There are 2 seperate outlets and diaphrams could they
both pack up at the same time ?

I have fixed it now. I stripped it down and reversed all the washers and
lubricated the rubbers with a little olive oil.
