Plastic pipes in general and PEX in particular are fairly new, so there is still much we don’t know about them and whether or not they can make water unsafe to drink. For now, we can say that they are a safe and affordable alternative to copper and lead pipes.
Research also shows that plastic can contaminate drinking water by leaching unsafe chemicals into the supply. A study by Purdue scholar Dr. Andrew Whelton on PEX plastic piping discovered odors in drinking water exceeding the EPA’s guidelines in each of six PEX pipes tested. Puhui Pipe manufacturer in China

Put the pipe clamps onto the pipe before inserting the each barbed fitting into the pipe. Insert one end of the fitting into the pipe, pushing it in as far as it will go. It can help to heat up the pipe by dipping it in a bowl of very hot tap water (not boiling water) or use a little liquid soap to lubrie the barbs if you have trouble pushing the fitting in.
