An Easy Guide to Setting Up Your RV’s Rinse System


Do you ever wake at 3 a.m. in a cold sweat, worrying about your RV’s holding tanks? Probably not, but if you add a holding tank rinser, you won’t have to worry about that happening. This RV upgrade will offer confidence that the RV won’t make you sick the next time you use the toilet or sink after a prolonged storage period.

First, settle on a convenient spot.

The Tornado tank rinser is simple to set up, but there are a few factors to consider before starting. The Tornado should be installed as high as possible (approximately 3/4 of the way up from the bottom of the tank) on the end opposite the tank exit. This may be impossible depending on how you have your tank set up. If this is the case, you might also set up shop along the tank’s side right before the tank finishes. And before you go any further, ensure the tank is empty. Else, you’ll be dealing with a friendly, nasty mess.

2. Create a hole using a drill

Once you’ve found where to attach the Tornado, give the region a good cleaning so that the sealant you apply between the tank and the Tornado will stick once you drill the mounting hole. Carefully guide through the tank, be careful not to drop the plastic removed into the tank, and mark the center of the mounting point using the template provided. If you do, you may need to flush the plastic out of the tank by filling it after fitting the Tornado.

Third, set up the seal and rinser.

After a bead of silicone sealant has been applied around the hole, the Tornado can be placed inside. Use the included self-tapping screws to fasten the Tornado to the tank. If there was too much sealant, wipe it away. Take it easy over the next day while the silicone sealant cures. This is crucial since you don’t want the flange to shift when drying. If the installation is finished before the sealant has dry, leaks may occur.

Fourth, decide where to put the water hose.

The next day is here, so all left to do is use the given fitting and hose clamp to attach the provided hose to the rinser. If the clamp is tightened too far, the clear hose may be torn, leading to leaks. Get the plastic hose to the drains as quickly as possible. The hose can be kept from drooping using tie wraps. Attach the water intake to the frame or the floor using the provided L-bracket. The L-bracket can also be attached to the tube that houses the dump valve using a four ′′ hose clamp. The setup process has finished.

Rinser operation: step five

Just plug a standard garden hose into the water input and turn on the tap. The tank will make a whirring sound. This is expected behavior, as the Tornado spins rapidly under the tank’s pressure, spraying water everywhere. While the system is running, it is essential to check for leaks. Wait a few seconds for the Tornado’s tank to empty at the dump station before turning on the water. The sprayer will be aided in cleaning the tank’s surface this way. After opening the tank, let the rinse cycle run for a minute to guarantee thorough cleaning. Toss with joy!

The use of a two-tank washing machine is recommended.

You can install a Tornado rinsing system in your gray water tank. To allow for individual or simultaneous rinsing of either tank, follow the same procedures as before, but this time link the water supply hose to a “Y” fitting with shutdown valves.
