Hi All,

I found that my c1 was leaking coolant so investigated further and found that its one of the black plugs on the bottom on the end.

Is this cover or plug replaceable?  If so, where can I find one?  I have the unit off until I can get this rubber plug/cover replaced or repaired.

thanks for all your suggestions.

If it is not horrible it's possible an epoxy type solution for plastic might work.   It wold be a pain as you would need it turned off as it drys and it dry to work.  A big question is the motor still working?   When my original pumps broke the motor stopped working.

What i did and suggest doing is getting a new pump.  I bought 2 of these pumps from ebay and have not had any issues: http://www.ebay.com/itm/381066536924  Been running from around since a around end of week 1 of release.

I also got a molex to fan adapter as it keeps fan's going as long as psu is on.   I am not counting on any wiring from syscooling at this point.

I don't understand what that is referring to, can you take a picture please?

A picture would be nice.  I have a feeling he means the spot where the tubes plug into.     I could be wrong but I have a feeling that is what hes talking about.

i should have uploaded a picture to describe the leak better.

I told a friend of mine about it and he suggested that i get "water weld' which I did.

The leak is at the bottom....the right plug or cap.  is it a drain, perhaps? 

I just applied the water weld epoxy this morning.  Since the water is "purple" I'll be able to see if the water weld holds. 

I have to figure out how to upload pictures here too. 

It is not to bad open a photobucket account, trow them on there.  On posting you need to click the insert image button, the second row second one in.   And you will put a direct image link between the html code.

And bottom please take a picture.  I think bottom was way to open up the pump.   So only thing is with epoxy you might not be able to get in it if you need to on it's motor.    But if it's working that is not a big deal.

I could be wrong on which part though so pictures would greatly help.

Are you talking about the black rubber bridge hose between the two waterblocks?

If so you can replace it with a better hose and clamps.

not the actual bridge but the cap on the right side.  I figured it must be a drain plug/cap.

thanks to others on how to post an image.  I'll give it a try tonight.

Still not sure what that is :( Once uploaded, you post an image to the forums like this:

here is the image.

hopefully this helps the discussion.   ;D

Ah, on the end. Plumbers putty or similar + duct tape should seal that quite easily.

I agree......so we'll see.  but I need more coolant to verify.  I ordered some but it will be a few days before it comes in. 

Yep dogie is very correct.  I was thinking bottom of pump I'm glad you uploaded :).

Should be pretty easy to put a coat of something on the end.  And it should keep from leaking.  That is not a critical or special part just a cap so no real harm sealing it back up.

The only thing that might be a little tricky is some solutions may require dry area which if leaking it would not be.   So might make sure solution or putty is a good idea that it's able to seal even if it drips during instal of it.

I agree that it could be a little tricky.  I am hoping that if the water weld epoxy doesn't work that the purple coolant by virtue of the color will change the color of the white epoxy. When I get home later I'll check out my handy work with the water weld. 

Thanks again to all.

Yea I thought about some epoxy works great but needs to be dry to work.  So with a leak limits the options a little bit, but still lots of good options.

Not a problem let us know how it goes!

Update:

Last night when I got home i found a tiny spec of purple in the epoxy.  Yes there is still coolant in the c1.  ....I really didn't want to drain it all.  .....so I did another layer of the epoxy.  This morning I don't see any purple coolant. 

Based on the coolant loss when the hole did exist I need to put more in but don't have any left....it will be a few days so letting the epoxy set may help matters. 

I'll upload a new image soon so ya'll can make fun of the epoxy application.  :-)

made smaller

Thanks for keeping us in loop, let us know how it all works out.  I don't blame you at all on not wanting drain the coolant.  I would try a few different ways to plug it up before going to that.

best of luck!

I always find taping the epoxy helps it resist pressure that bit more, and duct tape is almost good enough to seal the leak as it is!

so here is the c1 with the water weld on that bottom cap.

Again thanks for all the suggestions.

Glad to hear you beat the leak it seems.   No drips at all.  Very good job. Hopefully that fixes it permanently.

Let us know over time if any change but I'm thinking you beat it :).

i am still waiting on the coolant.  This was my first device, ever, using coolant.  I wasn't sure if I could or couldn't mix so I looked online for the exact same coolant, which shipped yesterday, finally. 

So for a week now I am down 1Th.

I think it would depend on coolant.  I have tested mine with two different ones (one was cheaper).  I had no issues and have been running since week 1 or 2 of batch one.

That being said keeping it the same coolant is not a bad idea.   With a cooling system like C1 that is not being closed-loop I recommend having a little bit of backup gear.   I was like you once with the downtime.  I currently have extra coolant, little tubing, some cheap fans in case,  and one pump as standby.   Luckily I have not needed them but they are there incase.

even though I don't have the unit running there is still coolant in the unit.  .....and tonight I found that the patch didn't work, darn it.

it seems like the epoxy didn't hold, it came off like a used band-aid.   ;D

tomorrow I am going to Gorilla Glue the leak and see what happens.

Dang hope next one works better.  I think the key is finding one that say's it does not need to be dry when hardening.

With a little bit of wetness coming out from leak that could throw a wrench into a lot of epoxy's. 

This idea will sound crazy but if you have a sporting goods store that sales a little bit of boating gear it's likely to have some  different solutions that water does not effect as much.  I know I have one chain store that has this and they have a very small section of different sealants that some of them are made with water in mind.

The reason I think the epoxy didn't hold is you still had coolant leaking out...

Drain the unit, dry the area then re-apply. I'm sure it will be fine then! :)

The leak is definitely what is stopping epoxy.  But he is trying to save coolant :). 

Normally being able to dry in wet conditions would not be a issue.  Hopefully OP finds a solution around him that dry's when wet.

agreed on all parts.   :-\

the water weld was supposed to handle wetness, I thought.  "water weld"?  deceptive name if you ask me. 

if the gorilla glue doesn't work i'll need to drain it for sure and then bring the cap to a local plumbing store to find a replacement. 

Haven't you guys ever used JB Weld?
I have fixed tons of things with JB Weld, from Laptop hinges to fuel injectors. There is a quick version also just not as high strength.

Marine Tex is the bomb for me  ;)

I think Ace hardware sells it,yepper  ;D

It's more liquid than solid though.......

Still gotta be dry & free of coolant,but it works REALLY well  8)

A full 24 hours later and the Gorilla glue worked.  However, I while I didn't drain the whole unit I did take one hose off and removed some.  That took the pressure off that leak....so I think that helped a great deal. 

Thanks to all who contributed ideas to the task at hand.

Glad to hear it all worked out.   I'm hoping that made the difference with the coolant not pushing and leaking through the glue.

Stop back in a week or so and let us know, but I'm hoping it's fixed up :).

bad news.....another leak!   :(

this leak is on the plastic on the pump. 

Is there another pump that veteran c1 owners would recommend?? 

In the meantime I am back to the Gorilla Glue!

Sorry to hear that.  I have had 2 of these pumps working for a long time - http://www.ebay.com/itm/381066536924

If you are in US that one ships from US so it's quicker on getting it there.  Depending on your country if getting it from China is quicker there are other options to get this same pump from China.

It's a solid pump and actually is a tad more power the the original syscooling pump. (IE pumping faster).  Below is a pic of my C1 using it:

I like the idea.....Thanks!
