Pull Cable for Easy Dumping

This cable-actuated RV waste tank valve has a 36" long cable, allowing you to easily open and close the valve even when it is positioned in a hard-to-reach location. Simply install the valve between your RV's sewer pipes and mount the handle on the end of the cable in a convenient, easy-to-access place.

Pulling Valve Cable and Black Handle

When you're ready to dump your black-water tank, just pull the handle to open the valve. And when you're finished dumping, just push the handle back in to close the valve. No need to crawl under your RV to access the valve itself.

Replacing Your RV Waste Valve

Before getting started on the installation, you'll want to empty your RV's black-water tank and flush out the sewer pipes. This will help to ensure that your working environment is as clean as possible.

This waste valve is designed to replace your existing valve, which should have a hub end and a spigot end. After removing the old valve and flanges, lightly coat the outside of the new valve's spigot and the inside of its hub with ABS solvent cement (sold separately). Do the same with the open ends of your RV's sewer pipe. Then, insert the smaller spigot end of the valve into your 3" pipe, and slide the larger hub end over the pipe on the opposite side.

Works very well, and what i expected.

- 34466N4AB36GM

This is the OEM drop in replacement for my 2017 Grand Design Imagine 2600rb trailer. It comes with fittings to glue onto your pipes; I removed and discarded them; the flanges on the trailers piping exactly match this valve. I did find the screws that come with it are too short. They are 1/4 x 20 x 1.5" long. You need at least 2" screws and 2.25" would be best. I tried replacing this valve (due to me damaging it) with the Valterra valve (less $$) as I thought I could cut that cable to exact length thus making the pull smoother. That did not work out. I cannot get the allen set screw to hold the cable tight enough. So I am back to OEM as this cable does NOT separate from valve and the 36" cable is pretty much the exact length I need anyway. As a tip, replace this at same time as other valves so you can loosen all valves and it gives just enough slack in pipe to move out of the way and slide the new one in.

Ask the Experts about this LaSalle Bristol RV Waste Valves

  • Is There a Specific Length of Cable Needed For Spigot to Hub Black Water Valve
    There actually isn't any way for us to know what length of cable you need when replacing the black water valve on your 2018 Montana Legacy 3130RE so you would need to either take some measurements or make an educated guess. The good news is there are plenty of options for length: - LaSalle Bristol Cable-Actuated RV Waste Valve for Black Water Tank - Spigot to Hub - 36" Cable # 34466N4AB36GM - 48" Cable # 34466N4AB48GMA - 72" Cable # 34466N4AB72GMA - 96" Cable # 34466N4AB96GMA - 120"...

  • Which RV Waste Valve Body w/ Flexible Cable Can be Trimmed Down Shorter
    We had one customer try to cut the cable of the LaSalle valve # 34466N4AB36GM and they said they weren't able to reassemble the cable after doing so as the set screw wouldn't get tight enough so I would not recommend this valve if your plan is to cut it. We know the Valterra # TC372 can be cut down and work well so this would be your best option.

  • Installation of LaSalle Bristol 34466N4AB36GM Cable Actuated RV Waste Valve On RV
    If the current valve you're using can be disassembled so that the flanges can be removed from the valve body, you'll have a pretty easy install. Remove the 4 bolts holding the existing flanges to he valve body you're wanting to replace then slide out the valve body. Remove the flanges from the new valve and slide in the new valve. Then bolt hole spacing is an industry standard, so as long as the old valve has the 4 bolts that allow you to remove the flanges, you should be good to go. If...

  • What is Shortest Cable Length for RV Sewer Dump Valve
    The shortest cable length for the RV dump valves is 36 inches like the part # 34466N4AB36GM you referenced. You can loop the cable to take up the extra slack and it will work fine. The bigger the loop you can make the better as that will allow the cable to slide the easiest. We do have an electric version of this with the part # E40-8 as well.

  • Black Tank Valve Is Stuck Open
    Your black tank valve could be stuck for a couple of reasons. At the valve there could be an ice jam preventing the valve door from closing fully. There could be something else blocking the valve door. Let's say your grandson dropped some Hot Wheels into the toilet and now they are stuck at the valve. Another possibility is that the valve door or pull cable are stuck in some way. I would suggest forcing as much lubricant as possible into the cable and around the valve door to see if...

  • Do Hub and Spigot Connections Need to be Cut Off to Swap Out Drain Valve
    It depends on what type of waste valve you currently have. If you have a Valterra Bladex then you can replace the waste valve body with part # T1001VP for a 1-1/2" diameter or part # T1003VPM for a 3" diameter. If you have a different brand or you aren't able to swap out the valve body then you will need to replace it with the hub and spigot ends like part # 34466N11AB36GM or # 34466N4AB36GM respectively.

  • Replacement Black Water Tank valve for 2013 Arctic Fox
    If the sewer line you have is a 3 inch sewer line that slips into the both sides of the valve you have now the part # 34466N4BB72GM will fit and work well. You will need to use ABS solvent like # 3447530889 to install it as well. If instead one side fits into the valve and the other fits over you'd want the part # 34466N4AB36GM.

  • Replacing the Blackwater Waste Valve and Cable on a 2018 Heartland RV Bighorn Fifth Wheel
    If you're looking to replace your blackwater waste valve and cable, then I recommend going with an actuated cable valve. For these, LaSalle Bristol offers two options while Valterra offers none. Which of the two Bristols you choose will depend on your current setup. The first, part # 34466N4BB72GM, has a 72" cable and a spigot to spigot connection. The second, part # 34466N4AB36GM, has a 36" cable and a spigot to hub connection. You will need to review your setup to find which connection...
