We know you have questions

we’ve got the answers

What’s causing all of the odor problems in my holding tanks?
Odor problems are usually caused by leftover waste and sediment that is still in the tanks after emptying and flushing. Get rid of the sludge and you get rid of the odor. Using chemicals only masks the problem and does not fix it.

What’s causing the misreading problems with my holding tank probes or sensors?
Misreading problems with holding tank sensors can be caused by two things: Unclean tanks with sludge, paper, or calcium build-up on the sensors, or electrical problems with the sensors and control panel. In most cases, sensor problems are caused by dirty tanks.

If I purchased a pre-owned RV, did I get somebody else’s “foreign matter?”
Absolutely, because onboard spray systems and chemicals are not powerful enough to remove all foreign matter. Most RV dealers reselling an RV will simply fill the tanks full of chemicals, dump them, and repeat a couple of times.

Is a tank replacement necessary if there is an odor or misreading sensor?
Very, very rarely. These types of problems are usually caused by unclean tanks. A thorough hydro-cleaning of your holding tanks will almost always solve these problems.

Do cleaning attachments that an RV owner can buy really work? What PSI pressure are they operating at?
In many cases, these attachments will help some, but only if there is a minimal build up of waste matter in your tanks. Most of these consumer-type attachments, however, screw onto a common garden hose and operate at only 40 to 50 PSI, not the 1500 PSI that our specialized equipment works at.

How often should I give holding tanks a thorough hydrojet cleaned?
We recommend that your RV have a professional hydrojet cleaned at least once a year to keep foreign waste and other matter from building up. It’s also a good idea to have your tanks professionally flushed just before winterizing. We’ll also walk you through the things you can do in between cleanings to keep your RV’s sensors working.

How long does the process take and do I need to leave my RV?
The hydrojet cleaning process is scheduled by appointment and completed in about one hour, while you wait. There is no need to leave your RV, though we do request you to be on-site. We’ll answer all of your questions, review with you what we are doing, and give you some instruction for things you can do to keep your tanks clean and your sensors working between annual, professional cleanings.

How do I know if all of the waste and foreign matter is out of my tanks?
We welcome you to watch the process. You’ll see what we are flushing out through the clear pipe connector we use and you’ll see when the water turns clean and clear.
