How long should a propane 2-stage regulator last? I am getting about a year out of them. We have been full-time in our 5th wheel for almost 2 years and this is the third regulator, 5th since we got the RV in 2007. The reason I know it needs replaced is we have a Precision Temp on-demand hot water heater that fluctuates if the propane pressure is not just so. Also the stove does not light on the first two tries. Thanks in advance.

Mine is in its seventh season. Maybe a squirt of WD40 up the hose once in a while might help. Can't think of anything else they could need.

LP regulators last almost forever, at least 3 to 4 years or more. I rarely have to replace LP regulators and I am a tech at a large RV service center. I do have to replace the feed pigtails from the tanks to the auto switchover because THEY will leak at the hose crimps. Do the regulators fail and leak or you just "think" they are bad due to your Precision Temp water heater and your stove? If so, that is a BAD way to determine your LP regulator is bad. You need to have the LP pressure checked when you have appliances running and when no appliances running. LP regulators ARE adjustable if the pressure is not correct. If I were you, I would get rid of the On Demand and get a regular 120/LP water heater. On Demand RV water heaters are ALL problematic and as you found out, very finicky on operation. When you state the stove does not light on the first 2 try's. You mean the range top burners and you are turning the manual piezo knob to light? If so, THAT is normal. It can take multiple clicks on the Piezo to light range top burners. Doug

All of the regulators I've seen are adjustable, maybe yours just need adjusting? They sometimes get contaminated the that brown oily goo that collects in propane systems, which can affect the way they work. :):)

A HIGH PRESSURE LPG filter like is used on motor fuel applications will absorb oil and debris out of the dirty gas you are getting.

On demand water heaters are very suseptible to water2 pressure fluctuations. I think you may be throwing band aids at a problem that has little to do with gas
