The NSA monitors everything OLD_CURMUDGEON, more so for those that try to copy and paste material in their web-browsers.

Not all joist hangers were created equal.  Some hangers are meant for contact with treated lumber or use outdoors, other hangers will rust prematurely if used in these applications.  It's important to use the correct fasteners, also.  For decks, cheap hangers and cheap fasteners are the wrong way to go if you want the deck to last.

Evidently, the NSA has gotten to this site since a COPY & PASTE into a browser yields a "site Not Found" response.

NIBCO, a very prominent American manufacturer of plumbing fittings has for years used blue & red PAINTED (aluminum) handles on their valves, whether the typical "stop" design, or hose bibb faucets.  They use brass or stainless steel bibb screws to hold the handle in place. 

Sink faucets can be renewed w/ brass bibb screws which are chrome plated. 

ZINC collars are used on propeller shafts for inboard engined boats to act as sacrificial anodes to prevent electrolysis from eating the propeller shaft(s), or rudders.  There is a zinc plate attached to the trim tab on many large horsepower outboard motors for that very same reason.

Your domestic water heater contains a zinc rod which acts as a sacrificial anode to prevent (or forestall) holes being created in the steel tank.  In addition, some manufacturers of water heaters installed & advertised that their heaters were "stone-lined" or "glass-lined".... these concepts were incorporated to slow down or eliminate galvanic action in water heaters.  Now, IF you replace your water heater, you'll notice that there are insulating nipples available to isolate the heater from any electric circuits.

@Jon: Thank you for educating. Yes I to feel plastic is the best thing. Anyway I feel there will be a cure for metal as well in the future. I read an article where there are several research programs being conducted by several universities.

It should also be kept in mind, that while brass is a trully wonderful metal from many points of view, it's an alloy of copper and zinc, and in plumbing applications (probably more dependant on the acidity of the water?) the zinc can leach out from between the grains of copper (metal alloys are not compounds, they are mixtures) leaving you with a porous (and weak) copper sponge.  I've seen this with Delta kitchen faucet spouts (cast brass, chrome-plated) and also with old cartridge cases.  Bronze (copper and tin) might work better for such applications.  Of course, tin is nearly a precious metal, so bronze isn't as cheap as brass...

An Improved Handle
Jon Titus   8/29/2013 2:04:40 PM

The design of the handle makes it difficult to grasp and as a result, many people cannot shut off water completely. The Woodford handle has six projections that should improve a person's grip, but anyone with a small hand, arthritis, etc., still will have a difficult time. For a good image of the handle, visit: http://www.chicagofaucetshoppe.com/Woodford_17P_p/wood-17p.htm

I put two of the Woodford aluminum faucet handles in my lathe and cut off enough material so the handle has a flat face. Then I put a flexible-plastic Superior Tool "Faucet Mitt" on each handle and fastened the handle to the faucet stem. Look for Superior Tool part no. 3997.  Now I have larger, soft handles with six larger nubs that makes it easy to control water flow. The Faucet Mitts come as a pair--one red, one blue, probably for indoor hot- and cold-water valves.

You can try a spray or a bit of silicone grease. But if the brass and aluminum (or other dissimilar metals) make even a tiny contact and get a bit wet, you'll still get an electrochemical reaction and the corrosion will spread. I'd prefer a larger plastic handle.

The video I found makes the repair look simple. Of course it is simple if you use a brand-new faucet assembly inside a video studio. The faucet in the video never saw a drop of water. Also, replacement of the back-flow preventer valve takes more effort than shown. That's the problem with many DIY videos--the creators make it look easy, but it isn't.

The backflow preventer requires getting the stem of a small plastic part exaclty centered so the stem goes into a hole in a screw-in retainer. You must use two hands--one with a small screwdriver to try to keep the stem centered, another to screw in the retainer. Also, the video doesn't show how to remove the tan cap.  It's a snap-fit plastic part and requires some effort to remove. --Jon

Here's your problem:

Woodford Model 17 Repair - Over 100 Million Visitors‎

I wanted a better picture of the intact faucet so I Google'd it. This popped up as a featured ad.
 
If I knew 100 million people were trying to fix a product, I would try to find a different brand. :)
