Had mastertemp 400 heater installed about 2 years ago pool guy that did the install says this issue with it cycling is because I don't have enough gas flow to the heater. Is there a definitive way to confirm this before I spend about $3000 replacing the gas line?
The cycling seems to be worse when cold that is about 70-80 degrees, some days it runs for 10 minutes before the burner shuts off for 30-45 sec, but other days it only runs for 2-3 min then cycles. Is there an indicator light on the heater that confirms low gas flow?
The run to the heater is 70ft with 1 1/4 in ground pipe. I talked to one plumber so far he said that it should be 1 1/2 for a 400k btu heater. My house is 30 years old so he also says pipe could be rusted or have moisture in it restricting the flow, in addition to it technically being too small.
Sound like a correct diagnosis?
