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.

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,,, FN@#!#%& !!! 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?

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 ;)

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.

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.
