You Need To Perform an RV Holding Tank Flush

You Need To Perform an RV Holding Tank Flush. Unique Camping + Marine

If you’ve read any of our previous content, you’ll know that we harp a lot on the idea of implementing the proper holding tank care procedures, but many people may wonder, “Is a tank flush really that necessary?” 

We at Unique Camping + Marine believe it is. In fact, we recommend that you thoroughly flush out your black water holding tank for 20-30 minutes every 3-5 dumps using a rinser already installed in your RV, an external tank flusher, or a tank cleaning wand. 

In this article, we’ll show you why we believe regularly flushing your tank is so important!

Flushing your tank prevents residual waste from accumulating in the low spots of your tank and leading to increased odors.

Here’s the simple, undeniable fact: no matter how well your high-quality, bacteria + enzyme holding tank treatment digests waste, there will always be some residual waste that accumulates in the low spots of your holding tank. (To better understand this issue, please see our article on holding tank shapes!)

Some may argue that this isn’t an issue if you park your RV perfectly level, but the fact is that parking an RV perfectly level is extremely difficult. Plus, many holding tanks aren’t even installed perfectly level! The reality is that despite your best efforts, you will likely still have some waste residue accumulate at low points inside your tank if you don’t rinse it out regularly.

Even the most liquefied waste will need to be rinsed out manually, and we recommend that you stay on top of this issue by thoroughly flushing out your tanks every 3-5 dumps. This will remove any current waste residue from your tank and prevent it from accumulating in the future.

Failure to rinse your tank for 20-30 minutes every 3-5 dumps can often lead to unpleasant odors as the residual waste left at the low points of your tank starts to stink. It’s best, in our opinion, to simply remove this waste residue periodically, preventing odors before they become an annoying problem!

The Unique Method

As we say, whether or not you implement the proper holding tank procedures can make or break a camping trip. But the fact is that most RVers only focus on one aspect of holding tank care (such as, for example, using a good holding tank treatment) and entirely neglect all other facets of RV maintenance. It’s no surprise that clogs, odors, and misreading sensors are extremely common in the RVing community!
