Have you ever taken your RV out for a brusque stay at a favorite campsite and noticed that your water tasted or smelled differently? If so, at that place'due south a proficient chance that your water organisation needs to be sanitized and flushed out. This is quite mutual for those folks that simply use their RV occasionally throughout the summer months and typically store them most of the fourth dimension. However, even the full-time RV should still sanitize their h2o arrangement from time-to-time to flush out whatsoever mineral deposits or unwanted bacteria. In this tutorial, I'll share some of my experiences sanitizing my RV and some tips I apply to make it easier.

Drain your water arrangement

First, you will demand to bleed your organisation of any h2o. If you are at a site where you accept a abiding supply to water and sewer, yous can simply disconnect your h2o supply and drain your organization by turning on your RV water pump and opening all of the faucets in your organisation. This should purge most of your h2o out of your freshwater system and it will help to clean your greyness and black h2o tanks as well. For this footstep, you should continue the belch valves open for those systems until you accept fully tuckered your RV of all of its liquid waste matter.

Nevertheless, if you're in an area where you can't discharge your gray and black tanks, I highly recommend that you empty those tanks prior to pumping out your fresh h2o. In fact, it would be a practiced thought to manually drain your fresh water tank to avert any over period to your sewage tanks. Yous should also drain your water heater by removing the anode rod. For this task, yous volition need a 1 and 1/sixteen socket wrench and some Teflon tape.

Pro tip: Be sure shut your heater off and permit the water cool earlier you take this step.

In a previous column, I explained what an anode rod is and why you should remove it from your water heater when draining your water organization. The same principles utilise to this task as well. After you drain the h2o heater, yous should inspect the rod; if information technology has too much corrosion and so you should replace information technology. You will demand to tape the threaded end with the Teflon tape before installing a new rod or the 1 you are reinstalling.

Now nosotros're gear up to sanitize your water organization

For this step you lot volition need to refill your freshwater system with chlorinated water then you will demand a gallon of non-gel unscented bleach on hand. It's also important to notation that sanitizing your h2o system is not a quick process and you will need to let the sanitizer sit in the system for at least four hours though I recommend more time than that.

Once you have turned off all of your faucets and airtight your freshwater drain valve, you volition exist ready to get-go filling your system with freshwater. Y'all will need to make full your freshwater tank about half full and stop the flow of water for the next step which is adding the bleach. I too recommend removing whatsoever h2o filters earlier you brainstorm the sanitation process or you lot will have to supersede them before you refill your system with drinkable water.

Since you should never introduce pure bleach into your system due to its corrosive qualities, I use a different method of adding the bleach than using a hose and funnel and pouring the bleach straight into your RVs h2o intake line, which some folks recommend.

You may remember in a previous article about using v gallon buckets for storage and equally tools, and this next step is a adept example of using a bucket for both.

The dominion of thumb when adding bleach to sanitize your arrangement is to add ii cups of bleach for every 100 gallons of water. Because my RV has a twoscore gallon tank, a six gallon water heater and water lines which add together a more water I use ane cup of bleach to sanitize my system.

Next, I make full upward my bucket with h2o while calculation one cup of bleach. Once I accept completed that, I like to use my small water pump to pump the water from the bucket into my RVs water intake but as would usually. Near pumps will come with a minor hose for intake, simply you lot will nigh likely have to purchase a brusque hose to run from your pump to your RV. I recommend a piece from 4-6 ft. in length for this task (example pictured below).

After you lot take pumped in the sanitizer, resume filling your water supply as y'all would normally. Once your tank is full, turn off the supply line to the RV and go inside and plough on the faucets one at a time until yous tin odor the bleach. Don't forget the shower, toilet, and outdoor shower if you accept one of those.

Pro tip: Dedicate ane saucepan to hold your hoses and pump for this this task or others where h2o repairs may be involved. You tin can also go along spare parts such as hose gaskets or extra water filters in this bucket and when yous need some plumbing related part, yous know exactly where to find it.

Flushing your system

As I said earlier, this is a long procedure in terms of time, so you will need to await at least four hours before you affluent the system and refill it with water. Personally, I prefer to await longer than the recommended minimum time frame and I will sometimes fifty-fifty practise this step overnight.

That said, the next footstep is to bleed your system the aforementioned style as you did when you started this process. However, you can skip removing the anode from the water heater this time around. Once you drain the sanitized solution out of your RV, y'all refill your freshwater again. You may have to exercise this a couple of times to completely remove the sense of taste or smell of chlorine, just if the problem persists, you can dilute ¼ cup of blistering soda with a quart of h2o and apply a short hose and funnel to introduce this to your water supply and then flush again. Afterwards you're satisfied with the taste, reinstall your h2o filters if you utilize them.

If yous are moving from one campground to another and the drive is several hours abroad, you tin do this task by sanitizing your organization before you exit for the next location. This way, when yous reach your destination, you accept waited the required time and are now ready to flush your organization and refill information technology with freshwater. Function-timers that only use their RV for short excursions can even do this earlier they head domicile and so they tin can sanitize their arrangement earlier they go someplace else.

So there yous have information technology folks, safe travels and nosotros hope to see out on the highways.
