I have a new water heater with very little water flow to the hot side of all the faucets. Hooked a water hose to the braided hose of the hot side of the water heater and took the aerators off the faucets and just turned on the hot side of all the faucets to see if I could blow out any lodged galvanized pipe rust chunks.Nothing came out and still low amount of water. Any suggestions?
We are in California with many low nox restrictions but that would not affect the flow of water I would not think, although many people have had to add a flue to the underside of the heater for more air. I know we are a crazy state

Did you have proper water flow with the hose connected? What type of shut-off valve is on the inlet to the water heater(ball valve or gate/globe)? Maybe a bad gate valve or debris in the globe valve? Are there check valve/ball hot and cold nipples on the water heater? Any chance the heater is piped in reverse or the nipples are reversed?

No I did not have proper flow with the hose connected.
It is a gate valve
Yes there are check valves in both hot and cold nipples
No I checked the nipples and they are clearly marked and piped correctly.
Great questions

You need to try and back-flush the hot water piping. Disconnect the hot water outlet hose from the heater and have it discharge into a bucket. Force cold water into the hot water piping at a fixture(connect hot and cold hose bibs at clothes washer?) and see if the cold water will dislodge anything and end up in the bucket.

you can also put a washing machine hose (2 female ends) on the drain valve and hook a garden hose to it and pressurize the tank from the bottom. see if you get any flow out of the faucets then.
if you do then the shut off is not opening.
if you still don't then something is clogging the outlet nipple.

Yes
I am going to try that tonight and see what happens. I just was going to attach the hose to the hot water side of the washing machine. I will let you and Steve know how it goes
