I just had a new GE water heater installed and the hot water comes out looking milky white from the amount of tiny bubbles in it. After a few minutes the bubbles dissipate and the water is clear. Does anyone know what causes this? Is air getting in or trapped in the system? or is it a pressure of piping issue? I’d appreciate any advice.
Could also be the anode in the water heater. One way of eliminating it is to install an air eliminating valve at a high point in the draw off pipe near the water heater. These valves are normally used on a radiator systems but I have has some success using them with the same problem you present.
