I have low hot water pressure, cold water pressure is great.. The problem came on suddenly, started yesterday, was OK the day before. Hot water comes out full blast for a second or two, then slows rapidly to little more than a trickle. I drained the sediment out of the water heater, but got very little flow even with hot water valves open, and had to flush it out by turning the cold water inlet valve back on. Still got only a little sediment out. This didn't fix the problem, and I didn't think it would. I'm wondering if a piece of sediment has blocked the hot water out pipe? The heater is only 3-4 years old, and I don't think there is that much crud inside it yet. I don't drain or flush water heaters as often as I should, but they still usually last me at least 10 to 15 years. The plumbing is 3/4" Galvanized out of the tank, connecting to 3/4" rigid copper. Any ideas? Thanks, R.C.

Mixing ferrous and non ferrous metals is contrary to better plumbing codes and even the ASME do address this problem when people mix these metals and cause an electrolytic action all because the installer did not bother to use a dielectric fitting to isolate the two metals.

As this galvanic action takes place it not only blocks the outlet and inlet it can render the T&P useless and can create a very dangerous condition

Thanks for the reply. Makes sense to me, except that it happened so suddenly...But I'll try it anyhoo! Thanks again, R.C.
