Review on 🚽 Enhanced SmartDrain End Cap by Thetford 17733 by Mark Tompkins

I had to purchase this item separately as they do not come with a drain adapter assembly. I figured that since it's hard to get a good fill anyway, it would be important to keep the outlet clean to increase the chances of a good fill. It is true; You need good pressure. The problem is that these caps, while very difficult to put on and take off, do not properly cover the part of the outlet that makes the seal. Therefore, using it only adds to the frustration without offering any benefit.
