| Re: Need help with plumbing Stay with the 1 1/2 for the mag pump output. Magdrives like the bigger pipe, some pressure pumps are better with a 1 inch-not the case with Mag Drive. Check the manufactures site for more reasons. Keep your output nozzels at least 3/4 or else you may get a jet like spray cutting a hole in the other side of the display tank! |
