This Kit combines 2nd Gen. Waste Master Enclosure PN 5856, Mounting Bracket Kit PN 5911 and Vent Assembly Kit 5903. The kit has everything needed, except the Hose, to mount the enclosure and store a Waste Master 20 Ft hose with nozzle PN 5816 with the hose permanently connected. This eliminates the need to disconnect every time. The system totally simplifies waste management – the most challenging task for RVers. The hose sold separately, uses patented ‘Stay-Put’ Technology with 4:1 collapsibility so a 20 ft hose stores easily in the enclosure with the nozzle.

The Mounting Bracket Kit includes the Bracket and matching 3/8″, SAE hardware. The Bracket is a steel part, preformed, drilled and powder coat finished in Black and mounts to the underside of the RV (5th Wheel or Travel Trailer) I-Beam or Chassis with self tapping screws. Using 4 point support the bracket firmly anchors the enclosure by its outer ‘wings’ using the included hardware.

The Vent Assembly allows the hose to readily extend or retract with dump valves closed. The kit comes with a Female Cam Loc pre threaded with 3/4″ NPT hole to fit Air Release Valve (ARV); other required fittings, piping and elbow are all included. The ARV permits air flow in and out of the hose but seals up instantly in presence of liquid flow allowing completely normal drain operation.

Documents listed in the ‘Install’ Tab show the user how to determine the bracket and enclosure location based on the RV’s sewer outlet location and other relevant features and how to mount the Vent Assembly. A wide range of adjustment is feasible. A key factor is the ‘Drop Height’ defined as the distance from the bottom of the I-Beam to the top of the enclosure. The Mounting Bracket Kit allows drop-height adjustment from 1 to 4 inches, covering majority of applications. If your RV configuration requires greater drop height or needs the sewer outlet relocated, please contact us for a possible solution. We have assisted many RVers successfully customize their system.

To hook up, just open the enclosure door, grab the convenient nozzle handle, pull out the hose and plug the nozzle into the ground inlet. To store, close the nozzle valve, pull it out, collapse the hose back into the enclosure to re-store it with the nozzle. It’s that simple. The hose can be removed should the need arise.

If you need help we will gladly provide any advice and hand holding needed and share with you examples of other installations. Man’s mind when stretched to new dimensions never shrinks back to the old – once you enjoy the convenience of a permanently connected hose you will never go back to the old ways! RVers who have this system are simply overjoyed with it and are sharing their stories with others. So will you!

I have been a customer of Waster Master for the past four years and have been a RV’er for the past 25 years, owning class A motorhomes and 5th wheels. In my years of RV’ing the most unpleasant experience is black and grey water dumping. The bayonet style hook ups are at best inefficient and at worst a smelly unsanitary condition.

Four years ago I purchased a 2006 Alpine Apex that was fitted with the Waste Master System. After learning the workings of the system, I am extremely satisfied with the various functions the system performs. From the nozzle with open/close positions that prevent unwanted spills, to the clear plastic window at the nozzle, to determine the clean out is finished.

Friends who have RV’s and have seen how my system works, are quite interested in Waste Master, with the idea of retrofitting their vehicle or the purchase of RV’s equipped with this system. That is however, a limited option within the industry.

I do believe this is a far superior system compared to present archaic systems being installed in today’s RV’s. This to me seems to be a very strong selling point in the making of rv’s and I’m surprised more of the industry hasn’t upgraded to Waste Master. This is a system that is not limited to just Class A motorhomes, in my humble opinion.

I believe that my next purchase of a class A motorhome or other type of RV will be influenced by whether this system is installed.

We purchased our Waste Master hose a few months back but really wanted to add the hose storage to get the full benefit. We purchased the storage box from Drain Master but were not comfortable with the installation because of the possibility of drilling into one of our holding tanks. We called Drain Master for some advice. One of the first things they asked was if we would be in the area of their shop in Hollister, Ca in the near future. As luck would have it we had a trip planned to Monterey during the summer. They told us to come by and they would be happy to do the install for us. From the minute we showed up we were treated like family. Doug and everyone in the office were super friendly and invited us into the warehouse to look at other products and accessories. The installation was flawless and looks and functions as good as a manufacturer install. The system is amazing and turns one of the more unpleasant necessities of RVing into a clean and simple process. Great product, amazing service and great people!

Just had my Sewer Drain System upgraded with a Drain Master (RV Waste Master System) in Hollister, CA. They performed a great custom fit on my 2016 Solitude 300GK. Their craftsmanship and attention to detail is next to none in this category. This will make our hook-ups and stops so much easier, as we travel throughout the country…
