on my 2019 reflection the black tank valve is stuck closed, there is nothing in the tank except the a few cups of water and plumbing antifreeze from dewinterizing yesterday, but the valve does not move at all, anyone know a way without opening up the underbelly to get this freed up?

If the seal has dried out, and valve is stuck to it, it will take some form of lube to soak the blade/seal. You may try dumping a bucket of water/dish soap down stool, leave set overnight, before trying to pull open.

There are valve seal lubricants available, but not sure how effective they are for this use?

I leave a quality non-ethanol anti-freeze in black tank, to prevent this.

Try tapping on it with a hammer. Pushing inwards may loosen it enough to break it free.

This is why I don't like remote valves hidden in the underbelly. Any issues and it's a major project to get at them because they never seem to provide a good access port.

As suggested, you can dump very soapy water (might also make it very hot water) and then hope the soaking loosens it up.

You might also try both pushing and pulling. If you can get a little movement, you can probably work it free.

After that, it's likely underbelly surgery to get at the valves.

My story might be different than what you have but on our 2001 alpenlite and after a few winters in Az the rod was getting very hard to pull and push so after emptying the black tank I poured cooking oil in the toilet and let it sit over night and then it worked perfect. had to do every couple of years. Might give it a try. Bottles have gotten smaller so maybe more is better. chevman

Interesting [emoticon] How much do you use?(cup,quart,gallon?) and how big is your tank?

If the tank is empty and the RV is level the valve will be the lowest point and all of the vegetable oil will sit right there and sometimes do it's magic. Any water in the tank and the oil will float on top accomplishing nothing.
This has worked for me. Good luck.

located the dump valve and cut open the underbelly, took off the calbe and the valve moves freely, so cable is seized, strange for a 3 year old unit hardly used. held the handle end lightly in a vise and gave it a good dose of penetrating oil a few times over several hours, let it sit overnight, and still stuck,,, [email protected]#!#%& !!! so ordered a new one, unfortunately only comes with the valve at $180 (cdn)

Has anyone seen if any aftermarket place makes them in stainless steel?
