RSM Return help


Recommended Posts

I have a return pump that went out on my rsm. I was wondering if anyone has used a different type of pump and how you retro'd it? would a maxi jet 900 work good? Any help would be appreciated thanx

If you do not want to do any mods then you have to stick with the stock pump


To fit any other pump you will need to stagger them in the chamber with vinyl hose.

I just replaced one of my stock RSM pumps with a maxijet900. It's a close fit, but you can get it in there. And the flow's great -- almost too much!! I had to move the nozzles around to stop my softies from being battered.


BTW, you can just push the RSM nozzles on to the MJ pump.


I recommend this.
