On my last trip my city water connection failed. Most of the water went out the bottom of the convenience center, but some got into the front storage area. I found that the female threads on the all-plastic fitting would not hold the male hose connection in place (yes, pressure regulator was used).
I found brass connectors and replaced all of them; much better product.
