I'm replumbing the laundry room and need to buy some fittings before I start. I have an Oatey single lever washing machine valve in a box mounted in the wall. Currently has CPVC plumbed to it, will be replacing with PEX. I'm sure the valve has threads for the input side. Are these valves straight threads or tapered pipe? What fitting would be needed to connect the valve to PEX? I have to move the washer and pull the wall panel to get to the valve and I want to have materials on hand before I start.
