Rena API Filstar XP4 flooding my dining room!!

[Muad'Dib]

So a week ago I bought 2 used RENA XP filters a XP 4 and a XP2. Only one had the Quick Disconnect connector.
I setup the XP4 on my main tank and as I was heading to bed that night discovered it leaked 2 gal of water onto the floor and into the basement.
After some investigating I determined that the O-rings on the quick disconnect were not sealing properly and water was leaking up around them, then draining under the motor cover until the entire motor housing was full then it would leak out where the power cable comes out.
I've tried Teflon tape, Vaseline, Teflon tape and Vaseline at the same time,  swapping the motor for the one on the XP2, it still leaks.

I've had an XP3 in the past, and NEVER had a problem. this is super frustrating. I'm ordering some new O-rings from Amazon, I'm getting some of the original size, and some just a hair thicker. (same inside diameter)

Has anyone else ever had issues with an XP filter leaking and what did you do to fix it.

Thanks in advance.

Oh man, you are not having luck with equipment since setting back up!  It really is worth buying a filter new if you can.  I have never bought a used one that didn't leak, so now I'll only buy new. Good luck, I really hope this works out for you.

Were both filters in use when you bought them?  If no, I wonder if the o rings dried up and shrunk.

No unfortunately they weren't so that is a possibility.
I do have another set of unused RENA/API o-rings, but he said he bought these as spares when he bought the filter, so they may be dry too.
I'm going to order brand new Nitrile o-rings from Amazon.

So there were some of the Renas at one point that had a defective leaky disconnect valve. Either something wasn't 100% aligned or the seals just didn't seal properly. The fix on those ones was to replace the disconnect valve.

I have a few XPs still running, great filters.

Hi Jody,
Like I said in my post, I've had an XP3 before and never had an issue. I loved it, that's why I jumped on these two.

So if there was an issue with some of the Disconnects in the past, I wonder if the problem is actually the Larger o-ring inside he connect that allows the nozzles to pivot.  I think I may have to pull one apart and see if I can find replacements, because finding a new disconnect valve is difficult now that they have been discontinued.
