I've made sure that the holding tank is empty, but after a weekend of use the head seems to fill up or get backwash from the holding tank. Could something be caught in the joker valve or do I need to replace this valve? Could it be something else? Thanks!

Close the seacocks!!!!
Sheesh! I'm beginning to feel like the goose in the AFLAC commercials--I keep saying it, but nobody's listening!! Scroll back through the last week and you'll find a lengthy discussion on this very subject. The water is either coming in through the head intake or the tank overboard discharge through-hull. If it's coming in through the tank discharge thru-hull, it's filling your tank, again, which is overflowing back into your bowl. Your macerator cannot prevent it. If it's coming in through the head intake, it's not backing up, so your joker valve has nothing to do with it. The cure--but only while the boat is at anchor or in the slip--is a vented loop between the pump and the bowl. However, relying on joker valves and toilet dry/flush valves to protect your boat is foolish and irresponsible. Valves FAIL! Valves wear out! Vented loops cannot prevent "ram water" (water forced up the the hose) from flooding and overflowing the tank or bowl while underway. Keep the seacocks CLOSED except when the head is actually in use!

So did I. but
three people I know insist it's a goose...and if it is a duck, it's a BIG one! Whichever it is, it's the best commercial on tv...'cuz not only is it funny, but NObody forgets the product that damn bird is selling!
Maybe I should call their ad agency...'cuz I need something equally as effective at convincing people to keep their seacocks closed. 'Cuz open seacocks have sunk more than a few boats.
