No appliance company will hook up plastic lines--especially if the
tubing is polyethylene. If you've had it for 20 years with no rupture,
then someone is watching over you, or you're doing enough good deeds
to offset your plumbing skills.
If fails most often right near the compression crimp at the solenoid
valve. That gets the most stress from water hammer when the valve
shuts off. It's also the weakest part since you probably inserted the
ferrule into the end and then tightened the compression nut.
Once it starts leaking you could be looking at MAJOR water damage to
floors and walls. Even though copper is at an all time high, the risk
just isn't worth it to keep using plastic.
As for the pressure, if the saddle valve was a puncture type, I'll bet
the small hole has calcium buildup. Shut off the water, remove the old
saddle valve and snip off the puncture probe (or wiggle it out of the
crimp on the valve stem) and drill the hold larger. Then re-install
the valve and clamp it down. That usually improves water flow and
pressure. (You may need to buy a new saddle valve if the old rubber
gasket has deteriorated. Not sure if you can buy just the gasket.)
