Help with leaky reservoir.

[Several Zombies]

So I was putting together a custom loop and noticed during leak testing that I had a small drip coming from one end of my tube reservoir. I double checked the tightness of the fittings and let the loop run for a while longer, but again found that it had a small leak on one end.

 

 

It seems to be leaking from either the lower hole, or from the O-ring. It's one of these old-school Danger Den tube reservoirs that screws together, so the end bits are only sealed with a thin rubber membrane between them. I also thought that the threads might be chipped, so I turned the top piece over and reassembled it, but that didn't seem to help either. I've checked the fittings around and above the leak, so I'm pretty sure the reservoir is the culprit.

 

My question is, can anything be done to ensure a good seal on these types of reservoirs? If the issue is the threads for the fittings, could I use teflon tape or something like that to help seal it even with a G1/4 fitting?

 

Any help is appreciated.

You can try teflon or some sealing silicon, but other than that you should probably buy a new res to be safe.

May be able to seal it with hot glue, depending on the location of the leak.

If it's the G1/4 fitting that's leaking try using teflon tape and give it a leak test to see if that helps, are the threads worn down to the point where the fitting can't apply significant pressure on the O-ring to seal it and the reservoir?

Hot glue should help that. Or you can use some other sealant

Something like that. 100% silicone sealant that will not shrink/crack/flake. Put a small amount around the threads of your fitting and screw it in as you normally would. It is critical that you allow it to cure in a dry temp controlled area for as long as directed, you don't want strands of that crap getting into your loop (or any other type of sealant). Thoroughly flush the res before you install it back in the system to make absolutely sure there's no contaminants.

As a last resort you can use something like this but primarily, i would contact the place you bought the reservoir from and see if that supply just the cap with the ports and just replace it.

Sadly I bought it nearly three years ago so an RMA is out of the question. Gonna try using sealant around the joint/screws and a bit of teflon tape on the G1/4. Hopefully that does the trick. If not, I guess it's time to replace the thing. Any suggestions for a cheap res of similar size?

I didn't mean to do an RMA, i meant to just see if you can purchase the cap with the ports and then you replace yours.

 

Best cheap free standing reservoir XSPC photon 270 and there is also the 170

If it's just the thread Teflon tape is the best option mate. Just be sure to put it on the thread the opposite  way to the thread.

Ended up using an all-surface sealant (which says it works on plastics and acrylic but we'll see) between the gasket and the tube, as well as the gasket and the caps. Cleaned everything thoroughly and applied it really thinly, screwed it all back together and let it cure. Seems to have done the trick. Cautiously optimistic right now. It just needs to last until I can afford a new one >.>
