Evening,
I have a newish Eheim 3704 400 lph air pump, which was virtually silent until the other evening.
Its now really noisy, so I decided that I would see what spares / service kits you can get.
Bought a set with 2 diaphragms and some felt pads in, fitted it all but its still really noisy.
Any ideas what else might be up with it?
Cheers
Matt
