The T-head coupler is intended to perform a cleaning-in-place of a blackwater tank inside a recreational vehicle, using a mixture of water and a cleaning agent. To accomplish this, the device includes a unique arrangement of ports and distribution channels, wherein the ports on the device are designed specifically to couple with ports commonly found in RVs and water sources. In addition, a container filled with a cleaning agent is attached to the bottom port on the device. When all attachments are made, a plurality of channels within the device direct incoming water to the container. The water mixes with the cleaning agent inside the container, forming a cleaning solution. The cleaning solution flows out of the device, using the pressure from the water source. The cleaning solution then flows from the RV port and into the blackwater tank, thereby cleaning the tank.

Machine for emptying, washing and sanitizing of the portable tanks used in the toilets of recreational vehicles (for example, campers, motor homes, caravans and boats), characterized by a structure widi sliding door, in which the tank is inserted; the machine comprises sensors capable of detecting the type of the tank inserted. The washing procedure starts by rotating the pour-out spout, unscrewing the lid and lifting the tank into a vertical position, thus emptying it into the drainage system. A coupling mask then automatically slides open the lid and opens all the valves and sealing plugs. A lance then injects water and detergent at high pressure inside the tank, thus washing inside. The machine then washes the outside of the tank and of the cap of the same, filling it widi sanitizing liquids, drying and re-delivering it to the user through its completely automated, electronically-controlled method thus guaranteeing hygiene and safety. The machine provides for direct connection to the sewerage system or to a collecting tank and backup systems for electricity and water supplies.

The other end of the drain control valve is detachably and hermetically connected to the self-priming drain pump. The self-priming drain pump is provided with a drain nozzle and a cleaning coupling. The drain nozzle is detachably and hermetically connected to a sewage pipe. The drain nozzle and the cleaning coupling protrude outside the main box body. The sewage discharge device of the present invention prevents users from contacting fecal matter and wastewater. Manual cleaning of the drain pipe is also eliminated, which is convenient to use.

The Recreational Vehicle (RV) Black Water Holding Tank By-Pass Piping Apparatus invention is a RV black water holding tank by-pass plumbing system that enables continuous use of the toilets within said RV while docked that is residential plumbing code compliant. Our invention consists of additional “Drain” piping , fittings and gate valves to divert the toilets discharge waste product when flushed around the RV's existing Black Water Holding/Storage Tank directly to the RV's Main Sewer Connection while at the same time maintaining the ability to flush the entire sewer discharge piping/lines with available waste from the RV's gray water storage/holding tanks as highly recommended by all RV manufacturers. This by-pass capability eliminates the need to “Routinely Dump” the normally accumulated black wastewater collected in the black water tank, a procedure that can be required typically every 3 to 5 days and one that can also, by the nature of the waste product being handled, cause severe illness if not performed with caution. Our invention does not require any replacement or reworking of any Original Equipment (RV) Manufacturer's (OEM) provided appliances or apparatus. All required components are external to these devices. Our invention can either be installed as part of the original build at the RV manufacturers manufacturing facility or as an add on or “After Market” addition at any Dealers or RV Equipment Suppliers facility/shop. While our inventions description describes a primarily manually operated system it can optionally include a partially automated wired or wireless automation control system. This invention minimizes the environmental impact of the use of black wastewater holding tank additives/chemicals by avoiding use of the black wastewater holding tank entirely thereby enabling the conservation of chemical additives commonly used by preventing the need to add them.
