I bought a home and the hot water tank was rusted out so I decided to install a tankless water heater. I installed it and it works but after about 3 months i started to hear a loud banging noise when the water was in use. I researched it and most people said it was jackhammering, i think that was the term, and that I had air in the lines. I am wondering how do I fix this if it is air in the lines and if it could be something different than air since it did not do that for the first 3 months.
Thank you for any help
