    Default Extended TPR valve

    I called out the TPR valve on this water heater as improper as I was trained that you weren't allowed to use "Extensions" because the standard sensing element might not get far enough into the tank to be effective.

    No extensions allowed (800x600).jpg

    I know there are TPR valves with "longer" sensing elements available, but don't know how I would identify them... and this just didn't look proper. The sellers plumber looked at it and originally said everything was fine... I am hoping he put that in writing, but may not have...

    What would you have called out or written?

    PS...the excess pipe dope doesn't count...

    Here are some Watts T&P relief valves with the extended sensor:
    - Temperature and Pressure Relief Valves, Water Safety & Flow Control, Watts

    Were you able to see the model number of that valve? The extended sensor one are all XL numbers.

    I couldn't get back to where I could get a clear view of the Model#... I might be able to take a picture "blind" and capture it. I get a chance later today as I got called back for a "Re-inspection".

    Wish I could find the old illustration that showed NOT to use extensions....

    That is one model, there are multiple models with extension thermostats - the OP photos shows a body style somewhat similar to the 100XL, LF100XL, LF10XL, LF1XL and others.

    Why does it look like one of these, tpr-valve.jpgis screwed in to one of these?

    thCASJB45Y.jpgIs it possible the Manufacturer designed it that way?

    I would recommend looking at the Manufactures recommendation for this item.
