    I have a Waterfurnace 5 Series with DSH installed.

    I do NOT have a buffer tank.

    I desire to lightly flush my current 80 gal water heater and was concerned about the DSH and possible introduction of air into the system. (been in the house 3 month and don' believe previous owner did this at all)

    Could you help me with the steps:

    1. turn off waterfurnace unit
    2. turn off water heater power
    3. turn off water supply to water heater
    4. open water heater vent
    5. open bottom drain
    6. turn water supply on/off/on/off to "stir up" sediment, while water continually drains
    7. close drain
    8. turn water supply on
    9. turn power supplies on
    10. turn waterfurnace on

    Thank you

    Go buy a buffering tank , fittings and some pipe. Until then leave the DHG switch off. If it is on power down the unit before turning off DHG to off. Points one and two are good. Nine and Ten are good. Go find Bergy's drawing here.

    Thanks for your input Mark. I can only imagine your terror/humor as you open my new post and wonder what king of ignorance I'll be typing this time.

    Goal is to put in a 40 gal buffer tank. I was just wanting to do some maintenance on my current tank but was unsure of the procedure as I have never had a DSH.

    Waterfurnance has a detailed drawing and procedure for installing the buffer tank and will compare this to Bergy's.
