Dump valves

Quick question for everyone. How often should the dump valves be replaced?

I've never had to replace any in the 5 MH's we have had.

When they leak or won't operate properly. Use silicone lube on the metal shaft.

I've never had to replace the valves on any of the RV's I've had since 1958.
10+ years on this one and they still work great. I do use a toilet chemical that has coconut oil in it. Guess that keeps the valve lubed.

I have been wondering this same issue. When my new to me 2010 Itasca just this past March, all three dump valves operated smoothly. Since then the black water valve has become harder and harder to pull out and push back in. I was considering replacing it soon but I would really prefer not to.

Is this a common problem or am doing something wrong? Can you tear the valve down without removing it, clean and lub the moving parts?

I'm with Mr D on this, you shouldn't really have to. Do you leave these open all the time when camping?

The only way to clean it is to remove it. Removing it is just taking out 4 small bolts and pulling the 3" PVC away from valve. Pieces of toilet paper get stuck in the blade and seal and sometimes even sandy grit from the flush water. When you put it back together lube the seal blade with plumbers silicon grease.

I just replaced both valves on our 1999 TREK due to some recent "weeping" surprises when I removed the drain cap. While I bought complete replacement valves for under $40, I noticed they also sold just the seals. While replacing seals only, or just cleaning and lubricating would have been less money, I figured it was easier to start with everything new. Installation is easy, but you have to put the black valve function out of your mind...

I just replaced the seals on our 2000 Adventure. Valve bodies were in excellent shape so I replaced seals only. I ordered them off EBay for about $15.00 shipping included. Replacing the seals was easy, getting to the valves?, not so easy. There is a lot of dissassembly required, but much cheaper than $105.00 an hour to have it done. They lasted 12 years with not a lot of P/M on my part so I shouldn't have to do it again hopefully. Ditto on using some type of seal lube in your tank additives. Coconut oil seems to work real well.

I just replace my black water valve. Not to hard to do. It was leaking and I found the unpleasant surprise every time I dumped. Total cost $14.00 from Camping World.

Also pour some mineral oil down the sinks and toilet to help lube the valves. There was a recent thread about this.
