Title says it all. I read and reread all the other posts asking this same question but am still unsure so let me lay it all out.
I am on city water using an electric HW heater. I have recently noticed a drastic drop in pressure on the hot side only (all faucets /showers). When I first turn the hot water on I have full pressure but after 30 -45 seconds I have a slow trickle (les than 1/4 of normal pressure). The first thing I did was drain the HW tank and put a wet/dry vac on blow at the highest faucet in the house. Oddly, no change! I placed a bucket to capture water from the HW heater drain and never saw particulates (no sand, etc). Next I turned the water back on slowly and watched the drain... no discoloration again. I let it run for about an hour to make sure the HW heater was completely flushed (and even turned the drain off twice to let the HW heater fill and re-drain). I never saw a single particulate. Hooked it all back up, cut the HW heater back on and I'm in the same situation. My question is this... did I miss anything or is there anything else I should check before cutting the HW pipe from the tank to the first junction (since this is where I would assume the clog would be)?
Thanks!

And I forgot to mention if this helps.. HW pipes are pvc.
