How to Figure Out Which Black Tank Valve is Needed

Question

Question:

The Black tank valve doesnt seal. I need to replace it but I dont know which one I need to buy. Id like to figure it out before we take the bottom apart to replace it. I would appreciate some assistance. I have a 2006 Montana 5th wheel. 2980RL.

We can offer steps on how to determine the correct black tank valve, though unfortunately isn't a way for us to know the exact valve that is on your Montana 5th wheel. To determine the right one is pretty easy, as you just need to know if the valve you are replacing slid over your pipe or into your pipe.

If both ends of your waste valve slid into your sewer pipe you will need the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Spigot to 3" Spigot # T40A.

If both ends of your waste valve slid over your sewer pipe you will need the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Hub # T40B.

If one end of your waste valve slid into a pipe, and one slid over a pipe you will need the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Spigot # T40.

To install these the only other thing you will need is the Valterra ABS Solvent Cement # A05-0303.

I have added links below to video reviews of each of these valves for you to check out as well.

LaSalle Bristol doesn't make it so that you can replace much on their cable actuated waste valves besides just the handle so you would be better off just replacing the entire valve and cable system with Valterra's Black #TC372 and Gray…

I spoke with my contact at Valterra who said that the Valterra Waste Valve Body #TC372 would be able to replace the Bristol Valve body that you currently have installed but that they haven't tested their cable kits like part #TC72PB with Bristol…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

Hey Vernon, great to hear from you again! For your trailer that has a GVWR of 11,295 lbs I actually recommend stepping up one level and going with the 18.5K #WS49MR which has the same 6" drop and fits a 2-1/2" hitch receiver like the 12.5K…

Hi Don; the difference between the #WS44MR and #WS82CR is the actual hitch balls. The #WS82CR has a stainless steel double-sided tow ball and the #WS44MR has a chrome-plated double-sided tow ball. Personally I would get the stainless steel option so…
