Leakproof Camlock Coupler

Camlock fittings on the Lippert Waste Master

This extension hose is specifically designed to work with your existing Waste Master hose. The hose coupler even uses the same leakproof camlock design that's used with the Waste Master at your RV's waste valve, so you don't have to worry about waste leaking between the hoses like it might with a typical bayonet-and-lug connection.

camlock coupler

To add this extension into your setup, first attach the extension hose to the camlock fitting installed on your RV's waste valve. Insert the hose's other end into the leakproof coupler and fold down the arms to secure it. Then do the same thing with your existing drain hose on the opposite side of the coupler. This will give you a total of 40' of length, ensuring that you'll be able to reach almost any inlet at the RV park while maintaining a leakproof connection.

Durable, Stay-Clean Hose

The Lippert Waste Master hose shown extended and compressed

Most RV sewer hoses have coils running along the inside where waste can get trapped, causing nasty odors and making the hose difficult to clean. But the Waste Master's inside is smooth, allowing waste to flow freely through the hose.

Also, the hose's durable and flexible TPV construction is resistant to crushing, abrasions, punctures, and UV rays, so it'll give you years of reliable use on your RV trips. Finally, the hose's large, strong end cuffs are securely bonded to prevent leaks between the hose body and the fittings.

Product works well and is simple to connect.
Used to extend septic hose to reach opening to septic tank about 25-30 feet away. Has worked for the past year and have had no issues !!!!

Good product great value.


I originally got a 20 foot section as my primary hose. There are circumstances where 20 feet isn't enough to reach the sewer connection. I debated about using a "cheap" hose and getting the connectors to switch to bayonet fittings. The clincher for me is that this product is so reliable and totally leakproof that it made no sense to go to something else. The 20 foot extension coils up to only 6 feet and fits with my primary hose in the same storage bin. If you want a trouble free sewer system, go with this product.


We have tried several RV hoses over the years but they leak or wear out quickly. We went with the Lippert waste hose a year ago and it has worked great. The connections are tight and easy to connect. We recently needed an extension kit on a rush so we contacted etrailer. They were helpful and got out the extension kit immediately. They kept us informed of the status and followed up to make sure we received the product and had no issues. We will purchase other items from them and would recommend them to others.

The product has failed me in workmanship


The best sewer hose available. Period.


The Lippert Waste Master is the best system I have used (40+yrs.rving) . There is no worry of a sudden disconnect as with the standard connection. You can twist, pull, or move the hose all you want and the hose will not detach its self until you flip the levers. Every part of the hose and connections are heavy duty. There is no dripping when disconnecting. The inside of the hose is smooth and allows faster and easer wash out. I use plugs on each end of the hose when stored keeping bees and debris out. The master kit comes with an adapter to fit the discharge end on your rig and an on/ off lever and site window. Pricey but, money well spent you will not be disappointed. Simple tools used, hack saw sand paper or file and abs glue. Dry fit the adapter and mark alignment before gluing.


As always, my purchase arrived on time, in good condition. In this time of national crisis, I expected my order would not be filled or shipped on time. The very high level of customer service experienced at etrailer has earned my respect and loyalty. I'm a very happy camper!



After a year of use, I am as thouroughly pleased as I expected to be. This is clearly a superior solution to the bayonet style waste disposal hose. We have had zero accidental spills, leaks or near misses. It is also much quicker to connect disconnect as well as far easier to keep clean.


I'm really glad you packaged the kits in seperate boxes. I guess UPS had to re-staple the big box but the smaller boxes inside were ok, not damaged.
The hoses look good and strong, haven't used them yet but seems like a great product...much thicker than other hoses and I especially like the cam lock.

Perfect! No runs, leaks or errors! Used 4 months straight. Very good sewer hose.


The Lipert Waste Management system is by far the best RV sewer drainage system on the market. I bought this extension for a back up to the main unit should I encounter one of those unusually far away site connections.


While the system is high quality, the seal at the outlet is JUST enough to prevent a leak during light use. It will not hold if you intend to use a maceration pump where the waste backs up a bit as it's being processed through the pump and leaks heavily. I've replaced the outlet and gasket at my expense only to get the same results. I called Lippert as well as the manufacturer on this who wouldn't help. So, in the end, for the 90% of the time I am at full hookup sites, it's fine. For the 10% where I'm on the road overnight or dry camping and want to dump at home with my macerator, it leaks.


I already own the Waste Management sewer hose which I really like and is clearly superior to the bayonet style sewer hoses and was easy to install on our motorhome. Adding the Waster Master Extension Kit will allow me to extend our sewer connection a 20 additional feet for those places where the sewer connection is farther away. This extension utilizes the same cam lock system as the main sewer hose so there is no chance for leaking like with the bayonet fittings. I would highly recommend this product and seller. Shipping was very fast and arrived in three days as promised.


I am very pleased with the products and the prices. If we need trailer products again, I will certainly look at etrailer first.

Not well. The main hose will not stayed extended. If you attempt to stretch it out, it will spring back to its original form and jerk the connection apart. I have the extension and it works find. There is obviously a problem. I would give this 2 stars

Thanks for the info. I have noted your order and one of our customer service representatives should be in contact with you soon.


Love the Drain Master hose system. I can literally pull the sewer hose out of its storage container and have it fully connected to the RV and sewer dump hole in 30 seconds. There is nothing simpler and faster on the market. Well worth the extra $$ IMO.


I love this product. Although when I used it the connection leaked. I realized the washer was missing. I need to call and have them send me one.

Having a leaking sewer hose connection is never fun. I will have our customer service department reach out so that we can have this taken care of for you quickly.


On time delivery and very professional driver that dropped my box in our front house in a right way.

by: is awesome to work with. Ordered a sewer hose extension which leaked,
called and they sent me a return shipping label and a new sewer hose extension no questions asked.


I highly recommend this product to evertone it will be the last sewer hose you buy. I works very well. I'm glad I got one, it cost a little but worth the money.

Bill G.


Very nice .good investment


We changed to these years ago and they are the greatest.
NO MORE TWISTING AND PULLING. They collapse to pack up and stay that way to store.
The cam lock connection is the only way to go ,you will love it. There not cheap, but worth every dollar.


What's to say about a sewer extension? It just adds length to the basic Waste Master hose.

Like the basic system it is well made and works well. No leaks which is what drove me to buying this pricey system in the first place.

However, I expect it to last long enough and without issues that I'll break even financially in the long run without leaks and trips to the stores to buy new hoses.


I ordered a Waste Master septic hose for my Rv. As usual with E trailer, from purchase to delivery the service was great !


I am very happy with Sara R , and her knowledge and personality made everything very easy ordering.


Fast shipping! Arrived home to find it on my porch. UPS destroyed the box! They could not even tape the box together in a sane manner. Box includes the coupler and hose. No end caps found. Please inform me how to obtain 2! No problem with etrailer but I have only used USPS and FedEx for years as UPS damages more than they deliver intact!


Product as expected, great service by salesperson providing an update as to deliver date which was exactly as stated.
As a constructive comment though,the telephone wait on a Monday mid afternoon inquiry would be rated a three start due to a 9 minute hold. The salesperson was very kind to explain that Monday's due to weekend orders did often create the delay. I reiterate though the agent was extremely apologetic and very accommodating.

Johnnie T.


Exactly as it was designed, used on multiple occasions.


I can only comment on service is first rate. Excellent selection of quality products.


Very happy with the one that came with the trailer so this is just a extension for when we need it.


Works as advertised, seller kept me informed about delivery as it was back ordered. Many thanks to E-trailer.
