I built a vac last weekend just like Iddee’s (see pics of his below) my problem is I don’t have any suction. I know my main problem is the the hose coming out of the vac is 1.25”, and my suction hose is 2”. So I am losing a lot of suction from that I guess. Do you think if I shorten the 1.25” hose to two feet or so that might solve it, or do I just need to get a bigger vac that has a 2” hose coming out of the vac with more HP. Below is the link to lowes on the vac I have.
