My water heater keeps popping really loud after we use hot water. I have drained it several times, and it helps for awhile but then starts back popping. I am always afraid it is going to explode or something. What can I do to stop this and is it dangerous? To drain it,I open the faucet thing all the way and let it drain till nothing comes out. I do see sediment in the last part of the water that is coming out.
Thank you
Sue
