Weird Leak

post #1 of 9
Thread Starter 
Hi everyone,
Installed my loop yesterday and started doing a leak test, straight away I noticed a little slow drip coming from the res/pump (Rasa 750 Kit) were one of the compression fittings is. So i tightened the fitting, leak tested again and still was dripping. So I drained the loop, pulled out that fitting and put a new one in and this time I warped it in Teflon tape just in case there was any tiny gaps in the thread.

I re did my leak test with again a drip coming from the same fitting just a little slower (one drip per hour) again I tightened the fitting with no luck.

The weird thing about the leak is it from the back of the compression fitting were the thread goes into the pump.

Last night before bed I decided to put to wraps of Teflon tape around were the leak is, I woke up this morning with not one drip.

I have no idea how the Teflon tape worked as it does not make sense at all.

Anyway I would like your thoughts on how to continue to stop this leak or could it be a faulty Pump/res since I have tried 2 brand new fittings with very little luck. I almost was going to seal it with silicon but I was unsure of the effect on acrylic.

Should I take the pump back under warranty?

Thanks in advance. smile.gif

Though I do not watercool, some of my info may make sense?

When you first wrapped the teflon tape, you have to make sure you didn't back it out for any reason.
Once that teflon tape is on, it's all about going right in, if you back the thread up just one tiny bit, it won't make a tight seal.

The second time when you wrapped, you may have added more, creating a stronger seal..

Check if you have tightened the screws on the pump enough, i had a familiar problem once smile.gif

Do you have an o-ring on that specific fitting? If you don't try putting an o-ring on it and tightening it down.

Yes there is a O ring on the both fittings I tried.

Pump is inside the res, this wont be the issue.




Thanks for all your reply's any other ideas would be great, leak testing again now hopefully the tape is enough to fix it. smile.gif

Really? its not new.. most plumbers use the Teflon tape on pipe..

Teflon tape wound around threaded pipe as above. Tape is typically wrapped three times around the pipe threads to ensure a tight seal and to prevent leaks.

I don't believe you read my first post, or maybe I did not explain it clear enough in the first place. I never pulled the fitting out before I went to bed, I just put the tape were the leak was not on the thread that is actully inside the fitting.

It does not make sense because the tape is usually wrapped around the thread and then tightened, here I put it on after the fitting was in just to buy some time to figure out how I would fix it.

EDIT: Realised this post came off a little blunt, no offence was intended. smile.gif

Well there may be something wrong with the on the back of the res.One of the threads could be cracked.Inspect it close And if it is damaged,I would contact XSPC about a replacement.
But teflon tape should be fine if it stops the leak.
But be sure you wrap the compression fitting threads counter clock wise And I would try 2 full wraps.

Take a really good look at the reservoir and check for a hairline crack in the plexi-glass or a nick in the o-ring. I would try to use a slightly thicker o-ring rather then the t-tape, btw i`m a master plumber with 35 years exp ( yes ancient ) if it`s a crack RMA it or barring that it can be fixed with an acrylic solvent cement. Lets hope it`s just the o-ring, good luck ! bike.gif
