What next? 22 Feb 2004 at 6:28 pm #295632 DUNBARParticipant Might have a defective dip tube in the water heater. Have a licensed plumber determine if this is the reason for the problem. http://www.waterheaterrescue.com “Your best interest is secured by making the right decisions the first time.” 23 Feb 2004 at 11:14 am #295633 Retired plbg1Participant Did you clean out sediment in bottom of heater. Check the therastats on the heater. Author Posts Viewing 2 reply threads You must be logged in to reply to this topic. Log In Username: Password: Keep me signed in Log In
