Black Tank Valve is HARD to Open

black tank valve is hard to open. This happens from time to time.

There's a third possibility. Manufacturers tend to coil cables that are too long in a tight radius. Use a fiber optic camera to look inside the underbelly. If you see that the cable has a tight radius, cut and shorten it or re-route it for less friction.

Water. I tell customers to fill their tank half way before using it. Personally, I drain my tank then use my shower hose to add water with the tank valve open just to help push those floater down. Once drained I fill again to halfway. No issues as of yet. I had a customer that would keep their grey tank open while draining the black tank. Complained of a smell from the sink. Was a good chuckle while educating the customer.

The way you explained everything with the visuals as well my friend well done you are an awesome teacher thank you

Good info Todd. As a profesional Bicycle mechanic I was aware about cable and what to use and not. I agree with you about not to use oil on the cables. I always enjoy your tech tips.

I bent my black tank valve rod which also caused gouges in the rod! Between the rod not being straight and the groves catching it was really hard to get it moving. I wiped the rod down, straightened as good as I could, smoothed with sand paper, wiped down rod again and viola!!! It worked!

Hey Todd, love the videos and have learned a lot. I have an in-line Valtera bladex black tank valve under our toy hauler and I can hardly open/close it. I don't see a way to access the inside of the valve without taking the pipes apart. If flushing the black tank doesn't remove what is blocking the valve, is it ok to run a black tank hose from the exit opening and try to thread it and flush that way?

Very nice and concise explanation. Thanks for sharing this helpful information.

Two things I’ve found helpful- Try to let a few hours go by between “introducing” solids and dumping.

Second, get a cap with the garden hose type port and attach a quarter turn valve. When you go to dump get the stinky slinky laid out, and before you take the cap off hold the slinky under the quarter turn valve and open it slowly. Once nothing comes out, you know you can take the cap off without stink sploosh.

One thing I have started doing is every time I empty my tank is after I close it is put about a gallon of fresh water in the tank and add a cup of gain liquid detergent in, helps with the smell and keeps everything nice and lubed and flowing.

What if the valve doesn't open all the way and you just get a trickle when you try to empty the black water tank? We had a technician come out and back flush the system and he said that it's not solids or a blockage. He said the valve isn't opening enough to allow anything but liquid through at a very slow rate. Thanks for any advice you can give.

I got it open admit it was tight, but got it then all the stuff is clear and gone, and water clean. sprayed the valve with silicone spray really well and will continue to spray if you tell me ok thats what i did and it ran very well thanks for your video really valuable it is closed all the way out and the wand did the job well

You just had to show corn in there lol

I spray my release valves every time they're used with a silicone based lubricant.

My camper sat for 5 years before I bought it with the cable valves open. Now I'm not able to close them. Can I loosen them back up somehow to close them?

[denniskwasnycia]

Stuck open is one thing, what about having a full load and the valve is stuck shut. How do you fix this? I managed to get mine open and flush it out, but is there a way to avoid this? When it was stuck closed, I could pull the handle out, but the valve would not open. This is a direct handle to valve, no cable.

Thanks for the poop on the poop tank! Keep the good stuff coming Todd.

My 2600RB Grand Design's black tank handle is frozen. I watched a video via 2krazykampers on how to replace it, but still hoping that is not necessary - and it says you have to purchase the the whole waste valve system, although you can pull the cable from the new unit and replace it rather than pulling the waste valve.

I use a white lithium grease. Worked fine but sounds like I shouldn't.

[jillconnell]

Can I use CRC Power Lube Industrial High Performance Lubricant With PTFE? Can’t tell if that a “Dry” as you mentioned. Thank you !

[TaroFields]

How do i know if the valve is NOT opening even though the hand lever does get pulled?
