Reply With QuoteDear All,
Any suggestion to help me solve the leak?? Or does any brothers have similar experience before and how did you stop the leak at the ports?
I am afraid of overtighten the PVC grey Nut and crack it and leak will turn to pouring water...
Dear All,
I had recently purchased a pre owned 2215 from one of the brother in the forum for my 2 ft tank. I set up the filter / hoses yesterday and discovered that the outlet port is dripping water when I hooked up the 12/16mm tubing from the preowned set. I checked and noticed that the tubing had hardened. There is no leak on the inlet port.
Today I went to purchase a new 12/16mm tubing and hookup up again. This time, there is still a slow drip of water from the outlet port despite tightening the nut and using a brand new 12/16mm tubing. Not a original from Ehenim though. Got from Seaview. Other connecting points are all ok, including a 90 deg elbow and the rainbar.
Is there anything to check and redo again as the slow drip is killing me..
I am thinking of changing the nut, as I noticed that there is harden residue in the threads.
Please help to solve the drips.
Thank you to all!

Try look for hairline cracks? Not sure if Teflon tape can help at the outlet connector...
Is there a visible O-ring on the output head? If yes then it is probably the cause, or the outlet has a hairline fracture on the plastic as mentioned by blurless. I would suggest that you have a good look at the output head. You can trace the source of the leak easily if you watch it closely.
If there is a hairline fracture on the plastic itself, in particular the output head, you might have to replace it. Part numbers you need to look at are as follows:
#7633000 - Cover
#7250600 - Sealing Ring (2 pieces)
If there is no leak anywhere else then you only need to look at these few parts.
Using Teflon tape might help but be very careful with the grey PVC nut. It can crack if you place too much strain on it. Clean the thread of the residue if you can see any. It should form a tight fit, but not a super tight fit. The tubes will harden over time, which is normal with the material. Replacing everything with brand new Eheim tubing is the way to go. Don't get me wrong, cheap tubes/hoses from hardware store is fine, but some are not meant for use with fish tanks.
Fish.. Simply Irresistable
Back to Killies... slowly.
Thank you very much to both for your suggestions. I will check again.
BTW, Stormhawk, can I know what do you mean by the green tubing which is non Eheim may not be meant for use with fish tanks?? Is it because of the low working pressure which might give way overtime?? Thanks alot for your help again.
Ehiem pipings are made of silicon, whereas other green pipes' content can be other materials, thus making the no-brand pipe to harden in 1 or 2 months of usage.Originally Posted by eastside
This is not recommanded as it ill cause leaking. On top of that, ehiem piping are thicker and the thickness of the pipe are ideal for the screwing nut to tighten it. the no0brand green pipe are thinner.
correct me if i'm wrong.

Have you consider having some of the white tape secure on the tip of the outlet? However you might encounter some difficulties inserting the hose to the tip due to the slight increase of size.
Hope you fixed the leak already. You can chose to replace the outlet part or use a bigger tube as shown. Hope it helps.2213_1.jpg
Hello all brothers,
Thank you for your input and suggestions. The drips stopped after one day without me doing anything to the tubing. I did not over tighten as I am afraid of breaking the PVC nut. I had applied PTFE white tape onto the make threads before assembly.
Hello Jin, your suggestion is a very good one using a oversize tubing with a hose clip. Will keep that in mind.
