Need plumbing help advice got a leak

[pizzaguy]

 

Short of it. Nitrate reactor. External mj1200 in pic. Pouring water out the bottom as you can see in pic. Went to petco bought a new mj1200 and still leaks with new o ring. Obviously the end is glued to the reactor so I gotta figure something out as I'm not rebuilding another reactor.

Ideas any help would be appreciated

It's a submersible pump and designed to leak under water. It's out of the water and working as it should. Get a Mag 2 instead. They're made for internal or external and don't leak.

This is basically what I copied

Supposedly, the newer Marineland Maxijet Pro's can be used externally. This is what the manufacturer writes, at least. Take it with a grain of salt. However, my experience is similar to Rob's: Maxijets in external applications is hit or miss - most of the time, they leak where the volute meets the motor block. 

 

Can you run your reactor in a sump so leaking is no longer a concern?
