When we re-did the kitchen in 2008, the lovely Carol chose a
fancy faucet with three levers (for hot water, cold tap water, and filtered drinking water)
and a sprayer. It's a "Rohl" U.1213 -- the spec sheet is at http://www.rohlhome.com/pdf/U1213LS.pdf ; I
found it very handy to refer to the diagram.
Naturally, we had some problems. The first thing, which happened some time last
year (but probably more than a year past the purchase date) is that the maximum flow rate
dropped. You crank the faucet full-on but after a half-second or so it acted like you'd
just turned it back down. The lovely Carol went to the retailer (Plumbing'n'Things in Redwood City), and
they told me to wash the valves (9.13247 and 9.13249 in the diagram). "How do you get
at them?" I asked. Turns out that you just pull out on the lever. It takes a little
doing, but the handles come off.
That didn't do it, so they put me in touch with the manufacturer. I called the number
(which escapes me now -- your retailer will have it) and the first thing the guy told me
to do was... you guessed it: wash the valves. I told him I did that already, and I also
mentioned that I was able to get full flow out of the sprayer (9.27434 or 9.27424). My
speculation, which I shared with him, was that the valve
that sends water to the sprayer (9.13157) --
that valve was going goofy on us. He concurred, and they shipped a new one at no charge.
I had a really hard time getting it properly installed. It
seemed as though the pipe was just a little too narrow for the valve. H'm... maybe
I should use some sort of lubricant? But I was out of time; I jammed it in as well
as I could and reassembled the faucet. Turned the cold water on full -- yay! The
only problem was that the sprayer was sort of half-hearted about doing its job.
I mean, it did spray, just not with much enthusiasm. And whereas before the flow
from the spigot would all but stop when I pushed the sprayer button, now it continued
at about half-strength.
Well, I was mystified but I sure wasn't going to disassemble the thing yet again;
I wanted to quit while I was ahead (getting full flow out of the spigot was #1; having
the sprayer work 100% was a distant second). Anyway as preparation for "someday,"
I asked my contractor friend about what kind of grease (or ...?) to use inside the
pipe and he suggested waterproof plumbing lube, which the guys at Barron Park Supply, 650-948-7160,
might know about.
That was back in September. Fast forward to this week, when the lovely Carol
informed me that the faucet was flopping around. I could see it, and knew exactly
what the problem was: the mounting hardware, in particular the C-ring (or C-plate?
it's part of 9.26400) was busted. Same drill -- visit the retailer, they passed on
the manufacturer's number, I called them, they agreed to send me a warranty replacement
part. (It's been over 18 months but they were very sweet about it.)
The part came yesterday, and since I was going to work on the faucet anyway, I figured
why not see about getting the valve in "right" this time. And since I was going to visit
Barron Park Supply anyway, why not try to find a replacement for the missing stopper control
knob/rod from the bathroom sink? So off I went.
Now their website says they're in the San Antonio Shopping Center near Sears, so
I parked in front of Sears. Our mini-poodle mix, "Popcorn," was in the car, so I left
it in the shade. I walked around the back of Sears, and... no joy. Fortunately I had
their phone number, and my cell phone. It turns out (I should have looked at
a map
first) they're a lot closer to the "Milk Pail" than they are to Sears. Anyway, I had the stopper control knob from
the matching bathroom sink, and showed it to one of the guys (they're all guys) behind
the counter. "I need one of these," I said.
"We don't have any," he replied. "You could order one. That looks like a Price-Pfister."
That sounded good to me, and he pulled a book down from the shelf. I entertained myself
with the news clippings on the wall, then looked around a bit. Eventually there was an
empty spot at the counter so I positioned myself there. The first guy was taking a long
time, and I wondered what was up, but fortunately I wasn't in a hurry.
But while I was waiting, another guy freed up, so I asked him about "waterproof
plumbing lube." He pulled a package off the wall (I *never* would have found it!) and
started describing some alternatives. I then told him what I was trying to do.
It turns out that the stuff in the package would work, but it was $10; he found a smaller
package, maybe a half-dozen capsules (small ones like Benadryl, not bigger ones
like CONTAC) of silicone grease. Perfect.
While he was still talking, I saw the first guy reach up and grab a box of parts.
He pulled out a knob/rod combination that looked quite a bit like mine. The rod
had a bigger diameter, but I was overjoyed. "You are the man!" I told him. He gave
me the original part numbers, in case I had to order them later.
Drove home without incident. Sure enough, the new rod doesn't fit into the
hole in the faucet. Harrumpf. Looked for my reamer... where did it go?
Oh well, one thing at a time. First, I crawled under the sink and installed the new
"C" plate. It's shaped like a large letter "C" and went on like a champ. The
original one was made of pot metal (I thought it was plastic but the parts were cold
to the touch) but it looks like they're making them out of something stronger now.
Now for the sprayer valve. I undid a small hex screw at the rear of the faucet,
and rotated the spout while trying to lift it. It took quite a bit of doing, but
off it came. Was it ever full of junk! I had a hard time removing the valve (9.13157);
eventually I hit on the idea of passing a common screwdriver blade through slits in
the spout and prying the valve out gradually. It's not supposed to be this hard!
Following the advice of the Barron Park guys, I took an old toothbrush and some vinegar
and tried to clean out the area the valve went into. After rinsing well several times,
I declared victory and put a little of the silicone grease on the part of the valve
that seemed to be hanging up. All looked good, so I tried inserting the valve.
No joy! How could this be? It just wasn't supposed to be this hard!
Here's the story: there's a part -- two actually -- that aren't on the diagram.
Passing through the spout is a hose for the filtered drinking water. It mates with
the aerator thingie at the business end of the spout -- 9.25553. The other end of the
hose is connected to a piece of plastic that looks like a tripod. In short, this is how the
filtered water gets out into the world. It turns out that this tripod-shaped
plastic thingie was what was hanging the valve up as I tried to insert it.
The way around it? Pull the unnamed tripod-shaped piece of plastic part-way out
of the spout's tubing, so that its legs can expand. Put the "top" end of the valve
(9.13157) between the tripod legs so that when the tripod-thingy goes back into a
narrower part of the spout, the valve will be embraced rather than rejected. Does that
make sense? The tripod's legs have "toes" that point inward. If the tripod is
placed first into the narrow part of the spout, the toes will reject anything bigger
than a certain size (7mm? diameter?). Naturally, the top-end of the valve is
bigger than that minimum size.
Therefore, what we must do is mate 9.13157 together with the tripod-shaped
thingie, and then push the whole shebang into the narrow part of the tubing.
And it works! Water full-blast when the hose button isn't depressed; respectable
pressure from the hose when the button is depressed.
That was it! I love it when things work as they're supposed to.
