So I bought a new Mag 700 pump for the right side of the RSM and it wont fit.. D'oh! I ordered it on-line on boxing day and was really hoping it would work but I guess not Any suggestions?
Last time I changed I used a Maxi-jet 1100 in the right chamber. I'm pretty sure left chamber is bigger so it should fit both sides. I agree with Al, keep the Mag 7 for salt or maybe later sump return pump. Good luck!
