leaking ddc-1 or mcp350

post #1 of 14
Thread Starter 
Has anybody else had a leaking ddc-1? I have heard of them dying but not leaking.

Mine leaks from the bottom. It is actually a 10W DDC-1vc with black impeller. The little white piece has cracks in it but so do my others. Is this normal? I am trying to eliminate the bottom 2 pieces so i cut the screws to length then i put it into use on my test bucket and it leaked out the bottom before i even plugged it into power. to verify that is is the problem I took the top off and filled it up with water while there was no impeller and it started leaking. I think I might just end up sealing the bottom off with something. I would also like to put Petra's top on them. If you want more pictures i would be glad to provide them. I searched the web and found nothing helpfull on the ddc-1vc. Do you guys have any advice I am at a loss?

Are the VC's like the bad ones so they put the bottom pieces on to seal them so they don't leak then sell them?

hey,

well unless you have the burning desire to throw a petras top on it, would just stick with using some sort of epoxy such as "JB weld" you can buy it at your local hardware store for <$10. you just mix a little of part A a little of part B and coat what ever is cracked with it.

An easier option would be to go to Walmart or any sporting goods /archery shop and look in the archery area for something called "fletch tite" it is a mild super glue that you could use, it dried in a few minutes and is very strong.

You could just order a petras top, put that on, and then epoxy it.

I assume your pump is not under warrentee, as this will void it.

So you wouldn't put on petras top? Just a top alone wouldn't fix the leak out the bottom. It leaks because of the little cracks or imperfections in the white piece. You are talking about sealing the bottom up right?

I am unsure about the warranty because I got them all used.

I have no experience with Petra's top, so I would assume that if you are using some epoxy/sealant that switching to a different top might pose some problems.

I would assume your warranty is void.

The fletch tite would be perfect for sealing up those cracks and imperfections. I was thinking that you could glue along the cracks, and where ever else might look like it might pose a leakage problem, a tube of fletch tite or jb weld is a lot cheaper than the cost of a cooked system.

Not too worried about it frying your system, the coolants tend to be non-conductive, I was more worried about pump frying from lack of water, chipset, CPU, GPU etc waterblock not getting cooled and frying.

Get a tube of clear silicone and use it...Your screws might of been a little over long and cracked it out...I really like the Petra tops...

Ill have to find something to seal it up. Ira-k what do you think about JB weld? I already have some of that stuff laying around, just dont want it to leak. The little plastic white peace was cracked before I cut the screws.

Have you guys ever seen this type of pump before?

I'd get a tube of clear silicone I don't really think JB weld would hold it very well, you can try it shouldn't hurt any thing....It's not leaking where it will get in the motor is it?


Yeah I've had a couple of the 10W like you have and I'm running 2 of the 18W in series with Petra tops...

Im not sure these are really weird ddc's (DDC-1VC). They have springs on the bottom that push up on a piece of rubber to seal where it leaks.

would Araldite work? If so where can you buy it at?
