Slow Flow
Bum water heaters make for poor showering
By Walter Jowers
AUGUST 9, 1999:
The quality of my showers has been poor lately. The flow from the
showerhead would be good, then bad. The water would be nice and hot, then
cold. I might expect this if I had one of those water-saving eco-friendly
showerheads. But I've got a reservoir-emptying, damn-the-ecology model,
which came with a warning: Caution--the force of the water from this
showerhead could remove your moles.
At first, I blamed my loved ones for my shower troubles. I'd come
stomping down from the shower wanting to know who had been washing dishes
or watering the lawn during my critical 8:30-8:45 a.m. shower period. Wife
Brenda and daughter Jess would deny all water use. Then I'd start to wonder
if they were messing with me, turning faucets on and off while they had me
helpless, stuck in the shower with my hair full of shampoo lather.
"I think it's your showerhead," Brenda offered. "I'm pretty sure it's
all clogged up."
"What makes you think that?" I asked.
"Well, it's 15 years old," she explained, "and I think the same thing's
happening to the dishwasher." She opened the dishwasher door and showed me
an impressive deposit of crud on and around the spray arms.
I must admit, I get a little behind on maintenance at my own house.
After I spend all day thinking about other people's house problems, I'm
ready for some Barcalounger time. Any given day around 5 o'clock, if the
air conditioner, the refrigerator, and the cable TV are working, that's all
I need to know.
In the mornings, over breakfast, I speed-read a few trade magazines.
Last week, I finally opened up my July issue of the ever useful Journal
of Light Construction and came across the headline, "Water Heater
Failures."
It seems that there are more than 20 million faulty water heaters
installed across America. These water heaters have faulty plastic dip
tubes, which disintegrate into a sludge that clogs things like
showerheads and dishwashers.
What's a dip tube? Well, it's a tube that delivers incoming cold water
to the bottom of the water heater tank. Until the early 1990s,
manufacturers made them out of copper or steel. But sometime around 1993,
they switched to plastic, because plastic is cheaper than metal. Now that
the plastic tubes are disintegrating, industry sources estimate that 90
percent of residential water heaters made between 1993 and 1995 have the
problem.
Another symptom of the disintegrating plastic dip tube: weird swings in
the water temperature. This is because the dip tube is supposed to take
water to the bottom of the tank, where it's heated before it rises to the
top of the tank. If the dip tube falls apart, cold water mixes with hot
water at the top of the tank and does evil stuff like dumping alternating
hot and cold water on a showering man's head. There is some good news: The
American Water Works Association (AWWA) says that the plastic crud is
non-toxic.
Energy Design Update reports dip tube failures in water heaters
made by A.O. Smith, Bradford-White, Jackson, Reliance, Rheem, and State. I
know you're wondering: What might be the make and model of my personal
water heater? Well, don't you know it's a State, manufactured in
1994. Which means I'm hosed. Or tubed. Either way, I've got to call
my plumber.
According to the JLC, the fix for these defective water heaters
involves either replacing the water heater or putting in a new copper dip
tube. Either way, the whole hot water system has to be flushed out, and
every aerator and strainer in the house has to be cleaned.
AWWA says the faulty dip tubes (ironically, manufactured by Perfection
Corporation) typically carried a five-year warranty. They also say that
many water heater manufacturers are paying replacement costs, which range
from $170 to $300 just for replacing the dip tube.
I think just replacing the tube is a lame idea. I've seen pictures of
these hot water tanks. They're coated with plastic crud--just like the
inside of my showerhead and my dishwasher. Common sense tells me these
funky water heaters will continue to shed plastic. I say that's no good. I
say I need a new water heater, and so do the other unwitting victims of
these cheap-ass plastic dip tubes.
Last week, Brenda made me go to the hardware store and pick out a new
showerhead. I found one that promised 12 different spray and massage
settings. Later that day, as I was toiling away in my office, Brenda snuck
up to my bathroom and installed the new showerhead all by herself.
I don't know what a man has to do to deserve a showerhead-installing
wife, and I'm pretty sure I haven't done it. Still, I'm grateful beyond
measure.
I gave the thing a test-drive. It works. No more low flow. One problem:
I can only get three of the 12 settings going. Either that, or there's no
appreciable difference between most of the settings. I don't much care. My
shower life is much improved, and I'm happy about it.
