The refrigerator was my last holdout in replacing all polyflow tubing and copper
water lines (that go to appliances, faucets, and toilets) with braided steel
lines. I've valved all those lines, too. Oddly enough, the refrigerator was the
first to get valved and the last to get braided. In this case, it's not a
braided steel line (though it looks like one). It's a braided polymer line.
Actually, it's made from a product called "Engineered Polymer."
Note: You cannot use just any braided steel line for a refrigerator. You must
use one specifically designed for use with potable water (e.g., ice-makers) or
dishwashers. These are supposed to be lead-free, and that's the reason. Always
check and then double check the packaging to make sure. And, yes, this Danco
unit is lead-free but I didn't actually need to check that once much less twice
because it's polymer so lead would not be used as it might be with a metallic
I wasn't very sure what engineered polymer was, so looked that up. Here's what
the inventors said in their patent application: "Improved flexibility increased
resistivity to internal pressure and rupture, simplified manufacturing methods,
decreased manufacturing costs, decreased weight, and increased resistance to
What they didn't say was that it does better with heat, and from my research
that appears to be its weakness versus steel. Unless you are running hot water
to your ice-maker, this is not a factor. The line that was in place had been
used in two homes over 21 years and was simply "poly-flo" tubing. Engineered
polymer is much tougher than poly flow tubing, so no worries.
I was going to just pick up a 6 foot braided steel dishwasher line at the
hardware store. As you may have guessed, I obtained this rather than going to
the hardware store. I saw this in Amazon Vine and not only was it braided, it
contained a water hammer preventer.
This comes in a plastic bag that has a large white label on the back. The label
provides installation instructions and maintenance instructions.
As for the installation, like most any guy I install first and read directions
later. Whew, I did the job right! That was made easy by the big, "you can't mess
me" directional flow arrow on the "muffler" of this thing. I did know to look
for it, as such a device has to be directional. A big tip when working with
compression connectors: do not overtighten them. That destroys the ferrule that
makes the seal. Just hand tight and a quarter turn (after you firmly insert the
line into the fitting). When connecting or assembling any sort of tubing, use
the exact wrench rather than an adjustable one. Never use pliers!
The instructions don't exactly say to make a "movement loop" in the line, but
that is standard practice for flexible lines used with appliances.
As for maintenance, what's involved? Well, if you do the required maintenance on
your refrigerator, you pull it out every few months and clean whatever you can
in back. What I normally do is aim the refrigerator at the open patio door in
the kitchen and use the vacuum cleaner blower to blow any dust out of the
coils. I also gently wipe the fan blades with a cloth. But before I do that, I
check the ice-maker line at each end. Danco says to inspect this every six
months, but why not inspect it every time you pull out the refrigerator for its
When I'm done checking and cleaning things, what next? I clean the floor with
vinegar and a soft cloth, then roll the refrigerator back.
The instructions say to replace every 5 years. Most likely, that timeline is
based on the expected corrosion of the unit. Depending upon your water's
characteristics, this time may be less or more (in my opinion). If you've had to
replace quite a few toilet tank units and water faucets in your home, I
recommend subtracting a year from that time just to be safe. Make an Outlook
calendar appointment and/or put a big tag on there with the replacement date.
I did the tag method, because that works for me pretty well. For other things,
too--when I set out ant killer baits, I write the date on each one so I can
replace the old ones if I start getting ants in the house. The tag method will
not work if you are not also doing the required maintenance on your refrigerator
and thus seeing the tag. To make a tag, I use the same method I use when tagging
all of my computer (and related) power and data cords. I keep yellow phasing
tape to mark things with. Just write on one half of a long strip, then fold the
strip over (sticky to sticky) around the cord.
I didn't have a big water hammer problem previously, now I don't have one at
