This is my opinion, not to be read as anything but an opinion. But I arrived at this opinion the hard way while camping in the hinterlands of Montana.

I think a spare sequencing valve is one of the critical spare parts that we should all have on board. Yeah, they are pricey, but it’s a cheap protection against having the potty disabled.

As my luck would have it, we had guests in the coach with us, and BOTH potties’ sequencing valves went nuts in a 24 hour span. One cracked, and the other would not properly work with any of the new o rings I had to rebuild it.

One word of caution, on the old style sequencing valves, is that removing the cap on the sequencing valve can aid in removal in the tight space. However, DO NOT remove that cap without relieving both the water and air pressure. Otherwise, you will be taking a shower as soon as the cap is unscrewed. Don’t ask how I learned this.
