stuck Y valve

Hey folks,

I've got a stuck Y valve on a new to us cat and I'm looking for suggestions to free up this sucker! Anyone got any ideas? I'm not looking forward to this job to say the least!

Try pumping some vinegar thru and leting it set. Is it stuck overboard or into the tank. I have been told it is not good to pump vinegar into the tank(kills bio organisms that need to be in tank) I recently took a stuck valve out and soaked it in vinegar , it works like new now. Once I replaced the guts of a valve with those from a new one leaving the old housing in place(saved lots of work).............HAVE FUN

I assume this Y valve is in the head, thus the lack of joy at replacing. In my experience, these valves are frequently left in one position for a very long time and take a set.

I have successfully freed mine up just by "worrying" it. That is moving it as much as it would allow over and over, eventually it started going full range and appears to work fine. If this succeeds, add it to your periodic/preventative maintenance schedule every couple of months.

The one I "fixed" was the plastic variety, not brass. Don't know if the success ratio would be different in different materials.

I assume it's the Gray Plastic Y-Valve located behind the head in the bow of the port hull. I don't recall any other Y-Valve on a Gemini--or at least on the one we chartered a couple of years ago to check the boat out.

Unfortunately, it's likely the former owner rarely if ever opened or closed the valve. Some owner's prefer to simply pump waste off-board regardless of what the law is or where they're anchored while others always use the holding tank, even when it's not necessary (as was the case on the boat we chartered). Absent working the valve periodically, they do freeze up.

N'any case, you may find that by heating up the valve with a hair dryer set on high and held 6"-8" or so from the valve, the heat will expand the outer shell enough to allow you to get the valve to move, even a little. (Don't try this with a heat gun as they put out too much heat!) If the valve loosens even a little, you can "work" it back and forth and slowly restore the action. Once it's moved a bit--try running a botttle or so of head lub mixed with warm water through it and you may be able to free the action up. Regrettably, replacing the valve may be necessary if it's thoroughly scaled up with salt and calcium carbonate.

Good luck!

Pour boiling hot water on will free up.

My boat neighbor swears by this. I would never do it, but.... he pumps some Sno Bol past the head and lets it set for "a while" then pumps it clear. he says it works wonders. Seems like it might do more damage than good, plus I don't imagine it's too good for the environment! Like I said, I wouldn't do it myself, and in fact I just replaced mine for the the same reason. Anybody else out there ever tried this?

The active ingredient in SNO BOL Toilet Bowl Cleaner is 15% Hydrochloric Acid (Hcl, Hydrogen Chloride, or Muriatic Acid).
