  1. What is the RV Sani-Con System?

    The RV Sani-Con is a 12-volt 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.

  2. How is RV Sani-Con better than the old way of emptying the holding tank?

    The RV Sani-Con is an electric waste emptying 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.

  3. 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.

  4. 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

  5. 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.

  6. What do I need to install my macerator pump?
    Installation of a macerator pump is very straightforward. Since the pump is powered by electricity, either DC or AC, the power should be shut off prior to connecting to the supply. Circuit protection, either an inline fuse or a circuit breaker should be used to protect the circuit. Most circuit breakers are polarity sensitive and should be installed with the lugs marked batt to the battery and the other lug, marked aux, should go to the device. Simple tools such as wire cutters, strippers, pliers, and screwdrivers are required to install macerator pumps. Inlet hoses can be rigid lines such as pvc or flexible hoses with wire reinforcement to prevent kinking or collapsing from the suction generated by the pump. Continuity testers for determining the available power supply may be needed. The pump should not be connected to any circuit that would be providing power to any other appliance that might be turned on simultaneously. Damage to one or both appliances might occur. Portable storage batteries with cables and alligator clips may be used to power the pump if a permanent supply is not easily available. The typical 400 amp portable battery will continue to power the pump for many empty cycles.

  7. What are macerator pumps?

    Electric macerator pumps can pump holding tanks and certain types of toilets and some can be used as macerators. They are not to be confused with Type I or II marine sanitation devices (MSDs). Macerator Pumps are very compact and lend themselves to installations short on space. Matter to be discharged passes through a bronze cutter which reduces the waste particle size, and is then pumped by the flexible impeller pump, discharging through a 1" (25mm) hose. The macerator cutter will usually not handle rags, hard objects or sanitary towels etc.

    • Macerator pumps break up solids, which minimizes clogging. They can be used to pump into a holding tank or to empty it overboard depending on the macerator pump placement.
    • Less water is required for flushing if a macerator pump is installed on the input side of the holding tank.
    • Macerator pumps can require up to 10 or 15 amps of power and cannot be run dry

  8. How do Macerator pumps work?
    For purposes of general information contained in this article, most pumps will be 12 volt DC electric.

    Macerator Pumps are designed to empty your holding tanks when fitted onto the plumbing in both recreational vehicles and boats. The function of the pump is to suction the solids and liquids from the lines connected to the holding tanks and grind the effluent with the rotating cutter head down to a small particle size for simple discharge of the waste. Eliminating gravity as a method to empty the tanks allows the user to lift the waste to a convenient receptacle either above or below the pump elevation.

    Electric pumps can pump the waste from holding tanks and certain types of toilets. The term macerator refers to the action of the pump that grinds the waste as it enters the inlet of the pump. Most macerator pumps are self priming, which means the pump will lift the waste solids and liquids up to the inlet of the pump and even further lift the discharge above the pump to empty into holding tanks or overboard if installed on boats. Macerator pumps help prevent clogged lines due to the function of grinding up the waste and smaller discharge lines are permissible once the solids are macerated. Less water is required for flushing toilets if the macerator pump is installed on the input side of the toilet.

    Installation of a macerator pump is very straightforward. Since the pump is powered by electricity, either DC or AC, the power should be shut off prior to connecting to the supply. Circuit protection, either an inline fuse or a circuit breaker should be used to protect the circuit.

  9. What happens if my macertor pump runs dry?
    Typically, macerator pumps are not designed to be run dry of liquids. The impellers will wear and the pumps capacity to discharge the liquids will be lessened. The most advanced designed macerator pumps will automatically shut off if the pump runs dry of liquids. The run dry protection is not designed to be used as a means to automatically shut off the pump. The 20 seconds delay will cause wear to the impeller of the pump.

  10. Special Notes for boaters
    Whichever toilet you choose you need to make sure your installation is fully in-line with local regulations concerning discharge. Many areas will heavily fine anyone caught discharging overboard. This means you need to install a Holding Tank to empty into until you can discharge into a dockside pump out station or directly overboard further out to sea. Macerator Pumps are designed to empty your holding tanks and include a bronze cutter to grind waste down to small particle size.
