To me that sounds like the hot water nipple is still blocked, (or blocked again).

Opening faucet lets air out but water cannot pass. You could try back flushing again, then filling the tank slowly.

Open drain valve with cold water stop valve open. You should get full flow and pressure out the drain. If you do, that should eliminate the possibility of blocked valve or blocked cold water nipple, leaving only blocked hot water nipple as culprit.

I tried this again, to no prevail. When I back flush the water comes in the hotside, and it definitely is, so that means there is no clog unless it has to do with the nipple right. Also I shut off the gas , this should not affect the pressure right? I do not want to call someone in in fear that they will have the same problems but will be charged to be told what I already know.

OK,
Close drain valve, fill water heater (washer hose removed) with T&P valve open. If heater doesn't fill in a few minutes you have restriction on the cold water input side. Then it only remains to determine if it is valve or cold water heat nipple. That of assumes that cold water is good every where else.

Before you go any farther you have to isolate the problem. Let me repeat.
To test the hot water lines first shut off a hot water angle stop and disconnect the supply. Place a pan over the angle stop and turn it on. You should have a strong stream, If you don't then the hot water mains and branches are cloigged. If you get a strong stream then I would check and clean every cartridge that's affected. Don't forget to turn the water on to flush out the supplies before you reassemble each faucet. Good luck, Tom
