Does this mean a head rebuild?
We have a PH2. When you pump it dry, it refills with disgusting water (that looks like it's from the holding tank) over the next 10-15 minutes or so. Does this mean I need to rebuild the head? Or is it something worse?

As disgusting as it is, some heads are actually plumbed to "flush" with the liquid from the holding tank. I had one like that once. Never could stop from getting creeped out by it.

You may want to have a look at the March/April 2006 Good Old Boat. It has a great article and diagram on "rethinking the head".

Sounds like you need a new joker valve. No joke, its supposed to stop the holding tank contents from flowing back into the head.

Here's a second vote to replace the joker valve. If it shuts properly, nothing should be coming back in. Sounds like it's full of crud (calcified probably) and needs to be replaced.

A lovely job, but someone has to do it. :)

PH II Exploded View Diagram
Here is the link from Raritan for the parts list and exploded view diagram of the PH II. If the joker valve becomes distorted in any way then it will allow fluid to feed back into the bowl. Before you rebuild the head, flush PLENTY of fresh water through so you don't get and back splash of the "good stuff". I have a WC , so I don't know if you can buy just the joker valve from Raritan. However, if you are fixing one part, you can bet that the other parts will go soon too. Once you get into a job like this you might as well replace all of the "consumable" or replaceable parts. Buy a full rebuild kit, or a whole new head unit. Sometimes the cost of the whole thing isn't all that more expensive than the rebuild kit. It's a matter of cost vs. convenience I guess. Check this link out either way (its a .pdf). Have fun, and remember to purge the thing with lots of water prior to taking it apart.

It's the joker valve. You don't need a whole rebuild kit unless other stuff is not operating properly but it is hard to find just joker valves at the local marine stores so you may end up buying a rebuild kit. Just tackle the joker first and if everything the rest of the rebuild kit for when something else goes bad.

I don't doubt that you are correct but...huh?!? How does it make sense to flush sewage with sewage? The whole point is to put sewage into the tank and out of sight/smell. Any head plumbed this way should be replumbed immediately. That's just dumb!:( :confused: :eek:

You won't be able to get just the joker from a marine store. You will have to order it from the OEM, Raritan. I've bought single parts from WC off of the parts list. Just be prepared to pay more for shipping than the cost of the actual part.

It's also possible that something has simply gotten stuck in the Joker valve preventing the sides from sealing - a simply removal and cleaning may do the trick.
