any "tricks" or helpfull tips for pumping 1 1/2 mix. dont do too much of it , got some coming up and dont want or need any surprises!   thanks

use a 5 inch tip hose. and a real slurry in front of the prime out. i.e. cement and water. not slick pack or oil. once you prime through you should'nt have a problem during the pour. so bring a bag of grout and a bucket and pump that shit out son.

We pump a lot of inch and a half.Use a yard of grout to prime, and I reduce into 4" pipe. And switch your s tube to hard throw. Works for me...
