Just a little tip. If the water system is empty we fill the tank then turn on the pump and fill the water heater tank than go to the furthest faucet from the pump and run until all the air is out. Then bleed the air out of all the other faucets including the shower and toilet. Then refill the tank to replace the water it took to bleed the air out.
Glad you found your fix and thanks for letting us know.
