After 90% of every holding tank cleaning we do, we’re asked how often an RVer should have the service performed. We’re hoping that the customer is impressed with how clean we’ve gotten their tanks; if you don’t know what we do, we wrote a great article on the process.

Our recommendations.

Our recommendation is that full-time RVers have their holding tanks professionally cleaned twice per year. While we’re happy to do that for them, we realize that full-timers tend to move around quite a bit. We operate under the All Pro Water Flow banner and there’s a list of our sister companies at their website.

All All Pro Water Flow companies have the same equipment, similar experience, the same capabilities, and relatively similar pricing structures. All are willing to answer your questions and travel to you (assuming you’re close by them) to perform our service.

For everyone else (and that means even if you use your RV only a few times per year), we normally recommend that they schedule professional holding tank cleanings once a year. A big part of our service is to listen to what you are doing now, discuss some options and improvements, and teach you better practices that will eliminate the need for more frequent professional tank cleanings.

If you’re in an area where we’re located currently, Kleen Tank is happy to travel to you to perform a professional tank cleaning. You can get a FREE quote for service by providing us just a few details about your RV. We also go to quite a few rallies throughout the year, so check out our Rally Schedule to see if we’ll be at an event you’ll be at.

And remember, if we’re not near you now and you need a cleaning, you can always check out the All Pro Water Flow website and their Dealer Locator to see which authorized dealer is near you now.

To be direct, no. Absolutely not. We were called the other day by an RV owner at a local RV resort. The customer couldn’t get their toilet to flush. “The stuff won’t go down,” she said. We knew exactly what the problem was.

What did we find?

We got the RV and took a look. All three gate valves were open and we knew exactly what to expect. The owner said she had her son “go and flush some water up into the tanks” but all that happened was the toilet overflowed and there was a gurgling sound from the shower and galley drains.

Long story short, the customer had a clog in the waste drain pipes from the holding tank to the flexible sewer hose. A big one. A monumental one. One that required we suit up in Tyvek. You get the picture.

So what happened?

Think about it. By leaving the black tank’s valve open, water and liquid waste seeps out. What’s left is a concentrated mix of solid waste and toilet paper. The more liquid that seeps out, the more compacted and dried out the solids become.

It took us nearly an hour just to clear the clog, plus another half hour to clean the insides of the tank with our hydrojetter. Eleven back flushes (one away from our record!) and the tank was finally clean.

The final word.

Many RVers leave their gray tank valves open. We’re not big fans of that either. Your RV’s holding tanks work best when there’s at least a 50:50 ratio of waste to water. Leaving the release valves open removes the water from equation. It’s not so bad in gray tanks, but those too can have solids drop out and accumulate in tank corners and other areas that don’t benefit from the rush of water when emptying the tanks.

Keeping the black tank valve open is just asking for trouble. Don’t do it and remember that your RV’s holding tanks are not a septic system, they are a holding system. Waste and water is intended to be retained in the tanks (essentially, large plastic boxes) until they are full and ready to be empties periodically.

We’re asked all the time: Aren’t my tank sprayers enough? The simple answer is, no.

All modern RVs have an onboard tank spraying system in their black tanks. It consists of a standard garden hose connection, bringing city or RV park water to your RV, a PEX line from there what travels to your hold tank (typically, the top, but sometimes the side) and ends with a nozzle protruding into the holding tank.

In most RV’s the spray system sprays in a fan-shaped pattern, though some systems have a spinning head. The nozzle head is typically metal, meaning that corrosion can become a problem long-term.

But there’s no substitute for the power of hydrojetting that comes from a professional holding tank cleaning.

Does the spray system get my tank clean?
No. It simply acts as a rinsing mechanism. The relative PSI from the nozzle head is between 100 PSI and 150 PSI, mainly from the reduction in the PEX tube and further through the nozzle head. Especially large RVs, like 5th wheels, where a tank (or second tank, like at a rear bathroom) is farther from the water inlet may experience even greater loss of pressure as the water travels to the black tank.

What about my gray tanks?
You’re out of luck there, unless an after-market spray system has been installed. There are some on the market, namely the Camco Tornado Rotary Tank Rinser and Camco Quickie Flush. You would need to have access to the tanks, something that can be difficult depending on the layout and architecture of your RV. It may require removing the belly pan on some RVs.

What is hydrojetting?
Using a heavy-duty, electric commercial water pump, we send a special, flexible wand up your RV’s sewer pipes, past gate valves, and into your tanks. There, water is pumped in at 1,500 PSI through proprietary nozzles. Water at this pressure scrubs the tank surfaces clean and breaking up built-up gunk, residue from enzymes and other tank additives.

Any clogs or mounds of waste (like in hard-to-rinse tank corners or along the front tank bulkhead) that can’t be removed by your tank rinser are easily broken up and ready to be pulled out during the rinsing step of our cleaning process.

It’s what we call hydrojetting and only authorized All Pro Water Flow dealers like Kleen Tank have it.

Do we use heated water or chemicals?
No, just plain water. We could heat the water, but it travels through the system at such a fantastic flow rate that it would have little effect on anything in your tanks. Likewise, chemicals aren’t needed as nothing is in your tank long enough to be dissolved or affected.

What happens next?
After the cleaning step, we remove the wand and cleaning head, and install a backlash valve between your RV’s sewer pipe fitting and the flexible sewer hose. There are two main types of backflush valves — both accomplish the same task — but we prefer the Valterra Flush King Back Flush Valve as it seems more durable and effective, compared to the Camco version.

What should I do ongoing?
Once you’ve had your tanks professionally cleaned (once a year is recommended — full-timers may need it twice a year), we recommend some simple steps:

• Empty your holding tanks when they are 90% to 100% full. If they aren’t that full and you need to empty them, add water either through your flush system (for your black tanks) or inside the RV, by opening the water taps in your shower or galley.
• Turn on your black tank spraying system when emptying your black tanks. That extra turbulence and volume of water will help keep things moving along.
• Use a backflush valve like the Valterra Flush King once every second or third tank emptying. It will help to keep your tanks clean between professional services. Use it on both black and gray tanks.

If you have questions about your holding tanks, RV waste system, or would like to schedule a hydrojetting cleaning service for your RV’s holding tanks, either locally or at a rally, let us know!
