grey/black water valves

[campin]

Can you recommend a lubricant for the grey/black water valves...hard to open and close. Thnx!

My black valve was sticking and I purchased this: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1. Thetford RV Valve lubricant. Followed the directions over 13 months ago and it has worked great ever since.

I use the same product. After dumping my gray or black tank, if I’m not going to be refilling them soon, I pour 4-5 ounces down, followed by a gallon or two of water. It seems to keep them working smoothly, especially if they sit for long during our blistering hot summers.

Thanx guys, will order!

See the thread below. I did the mod where you drill a small hole in the valve and squirt in lubricant. Both valves have been very smooth for a couple of years after doing this. Highly recommended.

Curious to know if you tried that and if so how did it work??

Also, has anybody had luck with a cleaner (enzymatic) the gets the tank sensors working again??
