stuck dump valve

[relaxin]

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?

NO WAY would I own another cable dump valve. One year and the Black was unusable. 6 years on the standard "T" valves and they operate like new.

what was the problem with yours, I have two and 6 years later they work perfectly.

Very difficult to open and close right from the get go. Finally stuck in the open position. Tried vegetable oil but that didn't help.

well I hope mine keep working, I wouldnt even know where to cut in the bottom of the rv to find tham haha. My biggest worry has been that some how the cable would unspin and come loose from the valve, even though I don't know if thats how there coneected or not.

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

I had this problem...valve was stuck slightly open, I used a camera to see what was going on. I cut the cable and relocated the handle right by the drain pipe so the cable is now shorter and straight, it was the cable that was the problem not the valve.

I also drilled a hole in the valve (another thread) so I can spray some lube in there. Oh and yeah had to cut bottom open to access. I got the schematics from Jayco so I knew exactly where to cut 😉

Yep, that's the problem with most oils - Since they're lighter than water, they float away after they're submerged.

Vaseline is also slightly lighter than water, but has better "stickyness" than most oils.

Heated to 140 degrees F, it pours like water.

I ordered just the cable and T-handle off Amazon Canada.

I replaceded the braided cables on mine with these last year after one broke.

These are a thin single piece similar to an electritian's fish tape.

I had to operate on the underbelly on my trailer also a few years ago ( not medically certified in my province but oh well....) due to similar issue with the handle. Was a pain to cut section of chloroplast out and get to the issue. I replaced with the one shown above also.

Does the handle possibly have a threaded keeper end to help keep it closed? Are you able to turn the cable or handle with it disconnected from the valve?

A long time ago in a land far away the wizened ancient ones entrusted me with their knowledge of keeping valves operating.

Google something like Zerk fitting in rv holding tank valve, bit of grease every now and then and no issues. Or search this forum.

This has worked for me. Good luck.
