In the event that you've spent whenever living the vehicle life or travelling in a trailer, you know there's nothing quite like the realization that are needed suburban hot water parts right when you're looking forward to the warm shower after a long day of hiking. It's among those things we frequently take for granted until the faucet stays stubbornly cold. These models are the workhorses of the RECREATIONAL VEHICLE world, but such as something that deals along with high pressure and constant heat, they eventually need the little TLC plus a few replacement units to keep chugging along.
The particular beauty of these systems is that they're actually fairly straightforward once you get underneath the hood—or rather, behind that little access panel on the aspect of your rig. You don't necessarily require to be a master plumber to swap out the particular basics, but you definitely have to know exactly what you're searching for.
The All-Important Anode Rod
If I had in order to pick the one piece among all the particular suburban hot water parts that triggers the most confusion (and the most avoidable damage), it's definitely the anode rod. In case you look in the bottom of your heater, you'll see a large hex-head bolt. That's your pluspol, and its entire job in living is to get destroyed so your own tank doesn't have to.
Suburban tanks are often produced of porcelain-lined steel. Steel and water aren't exactly close friends; over time, the water wants in order to eat the metal. The anode pole is a "sacrificial" part made of magnesium or aluminum that attracts most that corrosive motion to itself. If you pull it out and it seems like a chewed-up piece of gum upon a stick, it's actually doing the job perfectly.
Many people overlook to check these, and that's an error. Once that pole is completely blended, the water begins attacking the container itself. Replacing a ten-dollar rod is a breeze; changing a six-gallon tank because it's rusted through is really a weekend-ruiner. I usually inform folks to examine it at least once a period. If it's greater than 75% gone, simply toss it and thread in a new one. It's the least expensive insurance a person can buy for your RV.
Once the Electric Side Goes Dark
Most contemporary setups are "dual-fuel, " meaning they run on each propane and electricity. It's a great luxury to make use of the campground's shore energy to heat your water instead associated with burning through your own own propane reservoirs. But, the electric powered heating element is usually a common failure point among suburban hot water parts.
Usually, the particular element burns out for one very particular, very frustrating cause: someone turned it on when the tank was vacant. It only takes a several seconds of "dry firing" for that will element to appear. If you've ever flipped the switch, waited an hr, and still had cold water, the element is the start to appear.
Examining it isn't too hard if you have a multimeter. You're searching for continuity. If the outlet is broken, the particular element is toast. Replacing it needs a special thin-walled outlet (usually 1-1/2 inch), but once a person have the tool, it's a fast screw-out, screw-in work. Just be sure the strength is off and the tank is definitely drained unless a person need surprise bath.
Dealing Along with the Brains: Thermostats and Limit Buttons
Sometimes the heater works, yet it either gets way too hot or it will keep tripping the reset button. That's whenever you start looking at the thermostats. On the Suburban unit, they are usually found behind a black silicone cover labeled "RESET. "
There are in fact two separate thermal assemblies—one for the 12V DC side (propane) and one for the 120V AC aspect (electric). They're small circular discs kept against the tank with a brass bracket. Their job is definitely to tell the system, "Hey, we're at 130 degrees, stop heating today. "
If these fall short, or if the particular "Hi-Limit" switch kicks in because the tank got dangerously hot, you'll discover yourself pushing that will reset button continuously. These parts are relatively inexpensive and usually come as a kit. It's a good idea to keep an extra placed in your "emergency bin" because if they go, you're stuck with cold water regardless of how much gasoline or power you might have.
The Propane Side of the Puzzle
Whenever you're boondocking off-grid, that propane burning is the best buddy. But because it's exposed to the outside elements through the vent, it is likely to get unclean. Spiders, for whatever reason, definitely love the odor of propane and often build nests in the burner tube. This blocks the air flow and causes that annoying "roaring" sound or prevents the flame from keeping lit.
Typical suburban hot water parts for the particular gas side consist of the burner tube itself, the orifice (which is really a tiny brass piece along with a microscopic hole), and the electrode. The electrode is usually the part that will creates the spark you hear clicking when you convert the heater upon. When the gap is wrong or in the event that it's covered in soot, it won't ignite the gas.
Cleaning the burner set up having a bit associated with compressed air or a soft brush usually fixes 90% of propane issues. But if the electrode is damaged or the porcelain is broken, you'll need an alternative. It's a simple part, but it's vital for your "click-whoosh" sound we all love to hear.
Pressure Relief Valves and Leaky Seals
Have you actually noticed a little bit of water dripping externally of your RV heater? Don't panic just yet. That's usually the Temperature and Stress (T& P) comfort valve. It's a safety device designed to let off vapor (literally) if the particular pressure inside the particular tank gets too high.
Sometimes they drip due to the fact they're old and the spring has destabilized. Other times, it's because the "air pocket" at the top of your tank has been absorbed. A person can often fix this by turning off the water pump, opening a faucet to hemorrhage pressure, and then snapping the T& P valve handle a few times to reseat it. If this keeps dripping right after that, it's time to add it for your shopping list associated with suburban hot water parts.
Finding What A person Need
The good thing is that because Suburban is such a massive name in the RV industry, finding parts isn't like hunting with regard to a needle in a haystack. Many RV supply stores carry the basics like anode equipment and elements. Nevertheless, if you're looking for something specific like a module board or perhaps a specific wiring funnel, the internet is usually your best bet.
I always recommend double-checking your model number before ordering. You'll usually find it on a little sticker inside the particular exterior access door. It'll look some thing like "SW6DE" or even "SW10P. " The letters actually mean something: "SW" is usually Suburban Water, the quantity is the gallons, "D" stands for Direct Spark Ignition, plus "E" means Electric powered. Knowing your specific code makes obtaining the right suburban hot water parts a great deal easier plus prevents the headache of returning the particular wrong item while you're halfway across the country.
A Little Maintenance Goes a Long Way
At the end of the day, these types of heaters are extremely resilient. They're built to bounce down difficult highways and sit in freezing temperature ranges, but they do require an occasional eye. Flushing the particular tank every year in order to get rid associated with the white calcium supplement flakes (sediment) that will settle at the end can prolong the life span associated with your elements and maintain your water smelling fresh.
Taking the time to understand exactly how these parts function together turns the potential disaster right into a minor 20-minute fix. Instead of calling a mobile auto technician and paying a three-figure "house call" fee, you can just grab your own toolbox, swap out a limit change or an positive elektrode rod, and obtain back again to enjoying the sunset. After most, the entire point associated with having an MOTORHOME is the freedom it provides—and getting a reliable resource of hot water makes that independence feel a whole lot more such as home.
