shower water pressure

While unwinterizing our pod I noticed that the shower valve has an anti-siphon feature (this stuff is new to us as we got our pod last fall and managed only 1 trip before the snow came to the Sierra).  If you disconnect the shower hose at the valve you can see what kind of water flow you have there.  Could be the valve is blocked by scale from the hot water heater.  There is just a little hole on the top of the valve where the hose connects for the water to go through and the scale chunks I cleaned out of our tank when I put in the new anode rod could easily stop it up.  Also, since the anti-siphon valve drains the shower hose, you could have an entomology experiment in it that has blocked the hose.

Thanks, All, for the input.

Very easy, you should inspect the condition of your anode, probably yearly. Remove the anode. Of course do not have water connected and some say to release pressure valve and certainly do not do with HOT water in tank. As part of winterizing I have already opened low point drains. Use appropriate socket. Once removed your tank will probably have some accumulation of scale in the bottom of it. I could actual feel it with my little finger. You can clean it out by using a hose set on "jet" sprayed directly into the anode hole or with the small wand CAMCO sells that attaches to your hose, which is what I use. They scale stuff will wash out and be visible on the ground. The Kymooses video on YouTube reference "winterization" gives a visual. If I didn't winterize I would still do the water heater inspect and clean.
