After replacing the head intake to-hull valve and reassembling everything I have found that the head intake is no longer working. That is, I can try to pump water into the head with the manual handle but it does not pump any outside water in. The only thing I can think of is maybe there is something in the line stopping it up. Anyone had any experience with this? Thanks.

take the intake line off of the through hull, put it in a bucket of water and pump. IF it works the problem is in the new through hull fitting.

This happens to me every year I launch. Close the intake and a make a few pumps to create a vacum. Open the intake and leep pumping, this works for me.

Did you take the wooden peg out of the intake?

Another good trick to get it primed is to close the seacock, pour water into the sink until the basin is partially filled, then pump until the head begins to draw water. Now open the seacock, the basin will drain, but the head will stay primed. This is of course assuming you have the standard configuration with the head and the basin attached to the same seacock.

LOL! I did remember to take the wooden peg out Thank you for remembering.

Fortunately or unfortunately, the intake has it's own seacock under the fwd, port dinette settee, but that is an excellent idea using the sink basin.

I do know that the new valve is working since I opened it up after installation and let some water flow into the bilge. I can try closing and creating a vacuum and then re-opening and pumping. That might work.

I suppose it is possible that the intake hose is clogged. We have had some flooding and their is a lot flotsam around the slip, mostly dock foam. I noticed some in the old valve when I removed it.

Hopefully, I can get up there tomorrow and try again. If anyone has any more good ideas in the mean time please let me know. Just gives me more things to try in case one or the other doesn't work.

Thanks,

Kevin

All of last summer I used fresh water to flush the toilet (Probably not a bad thing to do if you are in salt water) until someone here suggested putting the drain plug into the sink basin. It's the same as filling the basin with water. Try it.

I think Ed is talking about the same thing I was going to mention. Does the thru-hull act as both a sink drain and a head intake? If so, plugging the sink drain should do it.

Thi happended to me once. It turned out that there is a "flapper" valve inside the pump handle housing which controls the flow of water into and out of the head. It's rubber with a metal disk. The disk had stuck to the housing and wouldn't allow water into the head. The fix was to lube the disk lightly with vaceline. Any other light lubricant would also work I suppose.

If you take the housing apart, be carefull. Over-tightening the screws can cause the anchors to snap and the housing will not seal.
