How do you clean my holding tanks?

Your holding tanks are basically large, plastic boxes that are either cubicle in shape (for most motor coaches) or long, flat, and shallow (most travel trailers and fifth wheels). Some RVs have actually very complicated geometry to them. We’ve seen these in some Winnebagos and Country Coaches, where there are ledges and different heights or nooks within holding tanks. No wonder it’s so hard to get them clean!

So how does Kleen Tank get holding tanks “factory kleen?” We use the cleaning power of concentrated, high-powered water at 1500 PSI (pounds per square inch). How high pressure is that? Well, the pressure of water from your RV park’s (or home’s outside) water spigot is about 50 to 75 PSI. Your RV’s onboard black tank sprayer’s pressure is about 100 to 150 PSI for comparison.

How do we get that high-pressure water into your tank? Simple. We attach a special pipe fitting between your RV’s waste system exit pipe and the articulated sewer hose that removes waste and sends it on to the park’s in-ground disposal or handling system.

Using a special six-chamber, heated commercial water pump, high-pressure water is sent up a tiny flexible hose that ends in a special cleaning head. This head is similar to what a commercial plumber might use to clear a septic line of tree roots, sand, etc., except instead of the head being the size of your fist, it’s about the size of your pinky thumbnail.

The cleaning head has holes drilled into the back of it to create a jet of high-pressure water that no only propels or drives the head through your waste system pipes and into your tanks, but also serves to blast away accumulated build-up within your tanks.

Once we’ve cleaned your tanks out, we use a special reverse-flush water valve that pushes water quickly and forcefully back into your holding tank, filling it up. This is then released quickly, flushing out any residual waste. This process is repeated until the tank is clean and the water coming out is clear.
