Frequently-Asked Questions

What is the RV Sani-Con System?

The RV Sani-Con is a 12volt powered electric waste system. Easily and quickly installed, the machine will allow you to empty the tanks up to 20 feet high and up to 350 feet away. The grinder transfer pump suctions the waste from the tank, grinds it up to 1/8th inch or less and transfers it through a small hose to the waste receptacle. Empty your tanks any time you need to, quickly, safely and cleanly. No rinsing the tanks with another water hose, do it all internally. Just hook up to the 3 sewer pipe and two wires to the 12 volt dc power supply and you are ready to pump your tanks. 22 feet of service hose, 20 amp breaker and completely assembled ready to use.

Do I have to rinse the hose after use? 

You do not have to rinse the hose after use. What ever is in the hose will stay there with the drip cap installed on the end of the hose. Just put the cap on the end of the hose and return the hose to storage for use.

How is this machine better than the old way of emptying the holding tank?

The RV Sani-Con is an electric waste machine. The pump and motor replaces the gravity system and allows you to empty the holding tanks 20 feet above the pump or up to 350 feet away. Now you can sit in your driveway, for instance, and empty your tanks into a sewer clean out up in the backyard, or a septic system cover, or even through a window into a commode. 5th wheels can empty up into an auxillary tank in the bed of the tow truck and then empty the tank at a dump station conveniently through a garden hose.

How do you know when your tanks are empty?

The pump and motor make a low pitch sound when water is being pumped and a high pitch sound after the water has been emptied. 

How does the gray water bypass work?

The gray water bypass system is furnished to allow the gray water tank to empty continuously around the pump if the discharge hose is connected to a sewer at the RV park. Since water will not flow past the pump unless the pump is turned on to run, the gray water bypass re-routes the water around the pump and into the discharge hose through the "T" and out the end of the hose in the sewer.

What do I do if I have a problem with the machine and I need to empty my tanks? 

The RV Sani-Con does not abandon the original plumbing. You can remove the connection and use the old system if required to empty the tank.

How can I install the machine if I don't have a large compartment?

The typical installation in a motorhome is in the utility compartment, which may be smaller than the other compartments,. The machine can be installed in any space that is 6 inches x 6 inches x 4 inches , and the hose requires very little space. The pump can be removed from the box and installed directly in the compartment. Since the pump is self-priming, it can be mounted above or below the sewer pipe in the RV, which allows many locations to be used. Class"C's" and towables can be outfitted with the RV Sani-Con mounted on the frame with the hoses being re-routed to an adjacent compartment. 

Do you still have to put the hose in the sewer opening to empty the tanks with the RV Sani-Con?

Yes.

How do I winterize the machine?

Pour RV antifreeze into the black tank and allow the pink fluid to discharge past the end of the sewer hose. 

What kind of warranty is furnished on the RV Sani-Con?

The warranty covers the entire unit for 12 months after the unit is installed. The warranty will replace any part that has a manufacturing defect. The RV owner must notify RV Sani-Con System of the defect within 30 days of discovery to replace the defective part or parts. 

How long does it take to install a system and what kind of tools is needed?

The installation will require hooking up the inlet hose to the sewer pipe and pulling the wires to the 12-volt power source. The time to do this will vary due to such factors as the number of barriers to the wire runs. Holes will need to be drilled to pull the wires and mounting the control box. The RV owner will need an electric drill and drill bits and common hand tools such as screwdrivers, wire cutters and wire skinners. 

Is everything furnished to install the system?

The items required to typically install the RV Sani-Con is furnished, including ring terminals and a 20 amp circuit breaker.

Are all items furnished to operate the RV Sani-Con System once it is installed?

Yes. 

How long does it take to empty the tanks if both tanks are full?

The pump will transfer 12-14 gallons per minute.  A 60-gallon tank will require 5 minutes approximately. 

Why don't the RV manufacturers install machines like this on the new RV's?

For 35 years, all the manufacturers have agreed to furnish the minimum system to empty the tanks. Regulations were approved to provide only the hose and connector. The gravity fed system has been standard ever since.

Can the RV Sani-Con System be moved to my new RV when I trade this one?

Cut the wires and remove the sewer pipe connection. It is ready to move. 

What happens if I don't get all the water out of the hose?

Don't worry about what stays inside the hose. The next time you use the system, the old water will be gone. The closed loop plumbing system provided by the machine will not allow the odors or liquid to get out.

How do I seal the discharge hose in the sewer pipe?

If the sewer pipe opening is larger than the threaded disc on the end of the discharge hose, install a gasket on the end of the hose. The gasket is usually a doughnut shaped device that fits around the end of the hose and into the sewer.

What happens if the pump is not turned on for long periods of time?

In the event the pump will not turn when the switch is turned on, the slotted end of the motor's shaft can be rotated manually with a straight blade screwdriver. The access hole to insert the screwdriver is located next to the switch on the control box. This is not likely to happen very often since the closed loop plumbing system prevents the interior components from drying out. However, the RV Sani-Con is designed with this provision.

Is the pump a new kind of pump?

The RV Sani-Con pump and motor have been used by the marine industry for 25 years. 

What is a "macerator" pump?

The macerator pump grinds the material taken into the pump housing and then expels the material out the discharge. 

I can hardly get down to hook up the hose on my RV. Will the RV Sani-Con make it easier for me to empty the tanks?

Yes. The RV Sani-Con System should make the task of emptying the tanks easier for you. You no longer have to hook up the hose or rinse it out before storing it away. Open the compartment and remove the discharge hose and insert it into the sewer opening in the ground. It is ready to use.

How long will the RV Sani-Con System last?.

The components used to assemble the RV Sani-Con are industrial quality and should provide long time use. All of the components are common off the shelf items. They have all been selected to provide the functions needed based on these criteria.

How do I get service on my system if it is needed?

You are welcome to make any request regarding the RV Sani-Con System. The information for contact us is at the bottom of every page of this site. Is the RV Sani-Con System patented?

The RV Sani-Con was issued a patent in 2002, for both the US and Canada.

Can the RV Sani-Con be installed on other RV's such as Class C, 5th wheels, and travel trailers.

Many installations have been done on all of the above, as well as Class B's, such as Road Treks. The pump may be removed from the mounting box and installed directly in the open to accommodate the space limitation requirements. The pump does not run submerged in water but is rated waterproof from wash off water and splash conditions. The warranty is not voided by this application in any way. The switch will need to be remounted if the pump is removed from the box. 

Can I install a second switch remotely in the coach?

Yes. The gray tank valve can be left open with the gray water bypass turned off. The gray tank will then fill normally and the switch to turn on the pump from inside will empty the gray tank

Can I leave the black tank valve open and empty the tank with a remote switch in the coach?

No. Never leave the black tank valve open to flow. 

Will the RV Sani-Con System pump uphill?

The system will pump 20 feet above the level of the pump. You may add extra hose of the same type and diameter as provided with the RV Sani-Con System to pump any distance as long as the end is no higher than 20 feet above the pump. 

Can I pump the tanks up into a truck mounted tank at the campsite?

Certainly. Discharge your holding tanks into a large auxiliary tank carried by the tow vehicle and deliver the volume to a dump station conveniently. This eliminates the use of portable, small volume tanks.
