Leaky pump

Well when i went to test it everything was fine except my pump is leaking.Its a mag3.Well i dotn know how to explain where but the peice that u can unscrew off is leaking.If that doesnt make sense tell me.Thanks in advance

It's common for Mag 3s to leak from the impeller housing. Unscrew that part. Then grease the o-ring with RTV silicone. Slap it back together and let it dry. You might find this link helpful http://www.wc101.com/reviews/danner/.

Try seaching the forums, I'm sure you'll find many posts about this.

Goop up the o ring of the impeller housing and use nylon barbs on the intake. If you dont have Nylon barbs handy use a metal hose clamp (the kind tightened with a screw) around the plastic intake (where the NPT threads are, just on the outside)
good luck

Man, that question has come up soo many times.
MODS, you should implement some sort of new-to-WC section. (I assumed IceBl@ster to be a newcommer beacuse had he done proper research he would have surely known about the mag3 leak) With such a section we could keep the WaterCooling section somewhat less cluttered with overly repeated Qs. IMO that would keep the WC section more interesting to in the knows or post-setup WCers.
just a suggestion.
