HIYA we have not used the plunger tap for our onboard water supply very much and last week camping at riverwood downs it stopped working , checked tank , was 2/3rds full , pulled tap assembly apart only to find the rubber seal stuck down the bottom of the tube , pulled it out popped it back into position , then put it all back together making sure the one way valve was in the right way , works like a new one cause it is new , i have no idea why it popped of , maybe suction /air lock who knows back to normal now ready for the next trip .
