Tip Waste Tank Dump Valve Lubrication

[J&JD]

No. WD40 Silicone. Not the regular WD40. Or any silicone spray.

WD40 makes a silicone spray. That is what I recommended, not plain WD40.

The right answer, as far as I know and have learned, is disassemble the gate valves, while you're at it replace your O-rings and lube the gates with food grade o-ring lube.

Well, it's been a couple of weeks since I lubed my three valves with WD-40. So far there are no leaks and the valves operate a lot better than they used to. So, my conclusion is that WD-40 isn't going to melt valves or make them swell up and explode!

Have you tested against Mexican or Indian food?

Well, I am in Texas. Just a couple of days ago I was munching on some stuffed jalapenos! I also like to put Sriracha sauce on things.........

Try WD50, I hear it’s 20 percent improved

Best to keep petroleum distillates off of all rubber. You are ok, but better to use silicone lubricant in the future.

Just had Indian food tonight. Yummm!!

I used CRC brand silicone water resistant lubricant. Did it approximately a week ago, dumped this morning and it worked easier with the mid 70 temps. Currently in Florida and when we had the recent cold spell go through it seemed more difficult to open and close the valves. Still recommend doing it.
