check your impeller
bro, is the pump head cranking with noise? is the impeller working(spinning)? better put the pump head and try on a basin of water to check/test first, see if this remedy works

An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a disc-shaped cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
Basically, it seals up the gap between the body and head, creating a waterproof seal. More information on o-rings: http://en.wikipedia.org/wiki/O-ring Most o-rings are made of natural/synthetic rubber, silicone or composites. Most do lose their elasticity over time. Hence, it is rather common that o-ring loses its sealing capability over time and you have to replace the o-rings. You can find the o-ring being attached to the side of the head; just imagine putting a rubber band on the head, just that the colour of the band is black. It looks like something on the first picture in the link: http://www.shop.trilbytropicals.com/...?categoryId=24 The Eheim filter manual suggests you to lubricate the o-rings. New replacement o-rings are pre-lubricated. |

I bought mine from QH, cleaner but more expensive. The lub sometimes become dusty and appear dry, or sometimes it gets absorbed into the rubber or other times it just really dry up.
