This may not be an answer you are looking for but I have the same or similar problem with decreased HOT water only pressure at all points in my bathroom that is serviced by it's own hot water heater. I am trying to find out where to start as well. Is it possible for sediment to get into the outlet line of the hot water heater and is the outlet line of the water heater up close to the top or is the suction at the bottom of the heater tank. I would like for someone to explain where it picks up the hot water in the tank, top or bottom ?
I hope we can get some help soon.
Thanks,
Kenny
Kenny, You ask, "Can tank sediment reach the outlet piping from the hot water tank? If so what can I do to clear it out?"
Yes it can. Minerals build up in the bottom of the tank. If not flushed out they will build up and get in the hot water system and clog the inlet ports of a cartridge or the seats of a faucet. Let me show you how to flush your water heater
For long life and fewer troubles you should keep your heater clear of mineral build-up by flushing on a regular schedule. Attach a hose to the boiler drain at the bottom of the tank. With the pressure on, open the boiler drain and let it run until the water runs clear. You will see a spurt of red,(rust) followed by white grains,(lime or calcium carbonate). This shouldn't take more then a few minutes. Do this monthly to keep it clear. Don't forget to flush it out every month. Your heater will thank you for it.
" is the outlet line of the water heater up close to the top or is the suction at the bottom of the heater tank. I would like for someone to explain where it picks up the hot water in the tank, top or bottom ?"
It goes like this. The cold water enters at the top of the tank and is directed to the bottom by the dip tube located under the cold water inlet. The bottom element heats the cold water and it raises to the top of the tank where it's kept up to heat by the top element. The hot water is then ready to be drawn out of the top at the hot water outlet any time you open a hot water faucet. Regards, Tom

I did as it was explained to flush/drain my hot water heater in the attic and
Guess what it plugged off MORE, so now I have not much more than a thick pencil
Stream at my bathroom faucets (ALL)
I really didn't see a whole lot sediment in the drain water but I throttled the
Outlet and inlet water valve off/on to surge the flow/pressure through the heater
And outlet piping.
I noticed that as I cutoff the inlet cold water 3/4 or more the heater went to
Really rumbling and it did have the burner lit and I was draining it as well
On/off.
I disconnected the outlet line from the hot water heater and found some crud
Maybe blocking 1/4 or so of the pipe nipple, I stuck a wire down the outlet
Pipe elbow and it appeared to be open plus I could hear the cold water entering
And it was blowing out some air at the same time.
I could hear the cold water rushing in with solid pressure as I refilled the
Heater. It refilled and then as I reopened the outlet line valve it only gave a
Quick little rush and then quiet with all faucets open.
I am thinking that it has caught mineral chunk in the outlet tubing and it has
Only pushed it further and harder to plug off more and more.
I was thinking of possibly rigging up from a cold water supply to a hot water
Supply at the faucets in my bathroom and then disconnecting the outlet line
Again or closing the cold water inlet valve and draining the heater down. I
Would then turn on the cold water supply and feed backwards into the HOT water
Supply lines to the hot water heater end.
OR I can use some compressed air to push one way or the other WITHOUT INVOLVING
The hot water heater.
What do you think ?
I need help BAD !
Please get back ASAP,
Thanks,
Kenny
