*by S***Y on 29 August 2022*

I am very handy and have done 2 bath renovations that included copper plumbing, electrical, drywall, tile and everything else that goes into a bathroom rebuild from the studs out. I am in the process of doing a reno on a new house that has PEX and I wanted to learn how to do it. There are plenty of tools available for this at the local home stores, but after doing my research on the Internet, I settled on this IWISS tool as the best PEX crimper for my DIY needs. I am not disappointed. The tool is very sturdy and solidly built. I only needed 1/2" crimps but it also provides for 3/4" crimps. I did not foresee nor need anything bigger or smaller for my DIY needs. Being my first time using PEX plumbing, I did a test crimp. That first one was simple enough to do and I felt the satisfying click of the tool as it completed the connection. It also passed the inspection using the provided go/no-go tool. So I laid out the new shower valve and all the connections for hot and cold lines and the shower head and handheld. I cut all PEX lines to fit and dry fitted the fittings as well. I also thought about how to put the connections back together and the sequence of the crimps, because even though PEX is a lot more flexible than copper, it's still pretty stiff when you're working in tight quarters. In all, there were 22 PEX connections to be made, so I shut off the water to the house and started crimping the connections. I was done in less than 45 minutes with all 22 crimps. This included 15 minutes to redo one connection because I did not seat the PEX all the way into the fitting for my comfort and redo another connection because I could not get the other side of the elbow to go into a tight squeeze. Because I needed to reuse the PEX tube (it was already cut to size), I used a dremel to cut to copper rings enough that I could use a flat head screwdriver to split it. I stopped the dremel short of seeing the blue of the PEX line and copper is a soft metal to split. This job would have easily cost $150 or much more if a plumber or handyman came out to do it. With this tool, some elbows and copper rings, I did this for much less than half and I learned how to do PEX in the process. I think I like PEX now that the initial learning curve is done and I can appreciate why the trades like it so much over copper. It's much easier and so much faster to work with. If you don't do this for a living, this tool is great for the DIY'er. And it provides great bang for your buck.
