Firstly, i am new to T&G. I bought the existing company and had the machine and product on board. I watched some videos and have done 2 jobs so far. Problem is, on the videos the sx-12 hardly leaves any water and when I do it there is lots of water left. I have to use the Gecko to suck it up. My method may be all screwy as I only have youtube to go by for training. Viper is mixed at 4:1 ratio Running at 700psi Sx-12 vacuum port holes on the ring are clear ( they were plugged solid when I first looked at the machine) Any suggestions? PLEASE!!
