I had similar problem. I could flush mine dry but it would fill back up when I sailed. The through hull was closed so I knew it wasn't sea water (or Lake Erie water in my case) coming in while heeling as can happen sometimes. It turned out the bore of the hand pump on my Groco head was badly worn. I wasn't able to pump air which is necessary in order to pump the bowl water over the hump on its way to the tank. Therefore, the water would slowly run back into the bowl. I ended three years of messing around with this issue simply by replacing the hand pump assembly. It's been perfectly reliable ever since. Your problem sounds a little different from mine so it what I did may not apply in you case. Andy Dalzell Cat 27 Hull # 6298 Sandusky Bay, Ohio In a message dated 3/7/2010 12:58:15 P.M.

hi all, the bowl of our onboard head is, oddly, full of clean water and when i try to flush or pump it dry it goes nowhere. the tank/overboard valve has not been switched since the last time i successfully used it so i'm a bit perplexed as to why this standing water is sitting in hy head. anyone have an idea? it has been raining a lot here lately but i can't figure how rain water would have made it directly into the bowl. thanks
