The RV propane tank regulator is critical to your RV’s propane operating system and appliances within the unit. Older systems that use a single stage RV propane tank regulator have had issues associated with atmospheric pressure and extreme temperature changes. The newer units use two stages featuring 320 PSI and can reduce down to 11 inches of water column.
RV propane tank regulators have an approximate 12 year life span. However, it is hard to tell the condition of the regulator just by looking at them. The RV propane tank regulator cannot be opened up, so you will have to look at some smaller, more subtle signs that the regulator is starting to be less efficient. Some signs that the RV propane tank regulator is not working properly include freezing of condensation in the area where the unit is housed. Exterior contaminants can also freeze up on the outside of the unit when it starts improperly working.
You may also see an erratic flame in the stove or on the stove top. If you are experiencing either of these, it might be best to take your RV propane tank regulator to a certified mechanic who can determine if the unit is bad or faulty. The mechanic will use a water column test to determine if the unit needs to be adjusted or replaced all together.
Another telltale sign of a malfunction is the smell of propane. This mean there is a leak in one of the seals of the regulator. If you smell propane it is best to get someone to look at the unit and determine where the leak is coming from.
Keep a close eye on your regulator’s housing and flames being produced by the stove and you will be able to catch issues with the unit before something small becomes a major repair job.
