Hi everyone! I carried out some maintenance on my JBL e1502 filter today and after turning it back on it started to leak after about 5-10 minutes. The photo shows where the leak is coming from.
I think it is the O-ring seal as it is in the places (front right and back right). Has anyone else had this issue did you just need a new O-ring?

You might have got the seal out of position maybe? Try taking it apart again and check all is where it should be. Try some vasaline around the seal might help it seal up.

I have taken the filter apart and put all the media, sponges etc back in places making sure it is all level. I've also taken the seal out, put it back and put vasaline around the seal but it only made it go slightly longer without leaking.

You haven't stacked the internal media baskets properly.

When the media baskets are stacked correctly the pump head rests with about 1-2mm gap all round, closing to 0mm when clips are closed. If you stack the baskets incorrectly there will be greater than 1-2mm gap on one end, but using the clamps you can force the pump head down BUT as you have found you get minor leaks. My JBL is from 2012 and if closed correctly doesn't leak.

Hi Everyone,

Minor setback. I have been checking the filter every so often and found a leak at the front right clip. I have changed the seal on the pump head.

When i took the pump head off it was full of water. Is this normal? Everything sound fine with the pump and the flowrate seems normal.

I have also had leaks where I trapped a plant stem/plant bits in the filter seal and it leaked slowly.

Yes and no.

When you take the detachable pipes off, the water left "behind the valves" drops out and, yes does get into the pump head, but generally is not much. If you are detaching the pipes, to clean, it is quite easy to just empty the water from the pump head.

And no.
The o rings on the detachable valves eventually wear. Mine became hard after 8 years odd and obviously let water leak slowly into the pump head. These are the official parts.
JBL O rings

I couldn't find them cheaper than £10 odd in UK. However I have replaced mine with 15mm x 2.5 thickness nitrile O rings from Ebay £1.50 for 5. Tried 15.5mm first, but water slowly dribbled through.

There's definitely no plant bits or dirt stuck around the filter seal. I'm about 3 hours from changing the seal with no leak so far.

I'm able to empty the water easily by tilting the pump head to one side into the filter body.

Are these the o rings that are part of the hose connector block? The filter isn't even a year old.

Mine was like the first image. Lubricating the old gasket worked for a few days until the new gasket arrived. I've ordered the nitrile o rings mentioned above and food grade silicone grease for gaskets and O-rings.
