    Strange noise from my heater

    I have a Hayward HD100 natural gas heater. Purchased last summer. Makes a strange noise after ingniting. The video is not mine, but is the exact same noise. Any thoughts? It seems to be getting louder.

    Northeast PA.
    10,500 gallon AGP Vinyl.
    Sand filter.
    Installed 2007.

    Sounds like a water flow issues, not enough flow and you possible have a leak as well.
