I was thinking about possibly putting electric waste valves on my 40x12 XLR and was wondering if anyone has any experience with them. And also recommendation on model of valve that has a good reviews.
No. The deal is, all the waste tanks have a 3" outlet. They are sized down before the 1.5" cable operated outlet on the grey tanks. So, to swap in a 3" outlet on your grey, you just install it forward of where it was adapted down to 1.5".
Instead of adapting down like mine currently is, I'm going to see how much trouble it would be to just change out the rest of the 1.5" pipe to 3" for my two grey tanks while it's apart. Wouldn't it be nice to have it dump twice as fast? It would also leave less scum in the tanks with a faster dump.
Karl4Cat I just found this on the link you shared earlier. It appears someone posted this same question on the FAQ site and there is an adapter that will work to reduce from 3" to 1.5" https://www.rvupgradestore.com/Drain...205dm30-cr.htm
Yes, there is an adapter but I'd rather have 3" all the way if it's not too much trouble to swap it out. ABS is really easy to work with. That adapter would certainly make a direct changeover very easy though...

Actually 3" pipe is four times the volume of 1½"!
