Black/grey dump valves

I posted here, although ours (1995) is not quite "vintage" yet, I found out today at the local Camping World that 'newer' mh's have a different (smaller) size dump valve on the grey water. Our's are both 3". And separate, not connected to one drain.
Anyway, ours (original I figure) were getting VERY hard to open/close.
$40 (@Camping world) bought both new valves, maybe 15 minutes labor and we are good !!! Being an old hot rodder, I'm used to doing things myself,
But now in a posistion (within reason) to have someone else get bloody..
It was Very easy, (make sure tanks are fully drained/cleaned) and I ran the front left steer tire up on one of our home made leveling blocks. (2x12's) to angle away from drains just in case.
It's always my job to set up/break down the mh, DW takes care of the "kids"(Danes) ... So now I'm a Happy Camper !!!! Thanks again to all on this site !!

Monkey, we have the two different sized drains. I see no particular reason for it and the manufacturer is now using the same size drain for the black and the grey tanks.

Theoretically, there should be no solids in the grey water to slow the flow and they can save money by using smaller plumbing.

My guess is the second 3" was done by a previous owner for some unknown reason? No reason I can think of to change back other than the inconvenience of switching the drain hose back and forth.

Regarding sticky valves, if you're doing your own work, you can pull them and lube the seals and shafts with a thin coat of silicone grease (I use dielectric grease). One finger operation after that treatment...

If you're paying to have it done, not that much more to just replace the valves. That might be a better plan at that point?

Isn't there some liquid cleaner/lube on the market, or pour a pint of mineral oil down the drains/toilet?

The plumbing is all original best I can tell. I'm fine with both being 3" as the hose hookups are separated by at least 6' . As I learned here, I drain the black when we are ready to leave, then attach to the grey, and dump that, washing out the stinky slinky..
It would be nice to know if there is a treatment to add to the tanks to have another many years of trouble free operation. ?? We use 'blue stuff' to help control odors, I'll have to read the bottle to see if it helps lube the valves also.

There is a lube/de-stink product, but I can't remember the name. Well, at least they claim it is a lube.

Like one poster said: "Can't hurt."

Might be a good idea when you winter/summerize.

The cooking oil worked great for our valves. I put a touch of grease on the shafts too. What a difference.
