Sounds like a good idea to me. I like the long sweep 90s. Plastic definitely restricts flow a lot more, and brass is always made from super thin cheap yellow brass that corrodes or clogs itself shut, especially on city water.
What gets me is if you talk to a manufacturer they say you must use. Their tool, fitting, tubing, and crimp or no warranty. Yet there is so much after-market stuff and so many brands are no longer available or the supply house switched brands and you need expensive minimums to get any. So if you're doing a small amount of work, you use whichever pex A or B stuff you have on your truck. And you can crimp pex A, in fact, the stuff that is splitting you cannot expand you have to crimp it. So where do we all stand on liability these days?
@@theplumberlorian This is just Viega but seems like if it's not all their stuff it's no warranty: Subject to the conditions and limitations in this Limited Warranty, VIEGA LLC (Viega) warrants to the owner of applicable real property in the United States (including its territories) and Canada that the components in its PureFlow Plumbing System (as described below) when properly installed by licensed plumbers in potable water systems, under normal conditions of use, shall be free from failure caused by manufacturing defects for a period of twenty-five (25) years from date of installation. The Viega PureFlow Plumbing System and components covered by this twenty-five (25) year warranty are: Viega PureFlow cross-linked polyethylene (PEX) tubing installed with PureFlow Press fittings in metal or polymer and PureFlow Press sleeves sold by Viega installed as a system. Viega PureFlow cross-linked polyethylene (PEX) tubing and ASTM F1807 metal crimp insert fittings sold by Viega and ASTM F2159 PolyAlloy crimp fittings sold by Viega installed with copper crimp rings as a system
Great point. We go with what we are most confident in. We know with a lot of confidence that these crimp style fittings work, so we use these on the residential service side. We have been seeing a lot of PEX-a split and crack so we don't re-expand it when we tie in. Crimp it down with these or Pureflow.
