I admit we do have a 1/2" gas supply, where the recommendation is 3/4". why would the unit work great for 4-5ish years and then have this problem now with undersized supply?
I have taken apart burner area and cleaned. Do you have a picture of what the flame rods look like? And also is this answer the same if it works when we turn water on and off multiple times and then once unit is on, the unit works nonstop turn til turned off?
yes it does sound that reignition is an issue. I'll have to wait until later when I'm at the computer to attach a picture.
can reply when you send a picture, can sanding down the flame rods help the situation, at least temporarily, or can that ruin the rods?
