How does one install a small length of very flexible water supply line between the female connector on the end of the fresh water PEX line and the mating male connector on the Tetford plastic assembly so that that a stiff incoming line doesn't stress the molded plastic valve assembly?
Simple. Buy a pump silencer kit
like this which consists of two 3' lengths water hose terminated with factory fit 1/2" NPT connectors. Both Valterra and Shurflo offer their own versions ... use one of the hoses and that will provide the flex you need. If the existing PEX connector that connects to the toilet is in an awkward location cut the PEX tubing back a few inches and install a compression fitting from SharkBite or SeaTech. Can't take but a couple of minutes tops for this fix.
