Hose off, now Thruhull problem!
Hi,
Finally got that old hose off with a hacksaw and a fair amount of flame. Problem is, I STILL haven't found the blockage! I usually find that if the blockage is in the thruhull, opening the valve with the hose off gives a blast of reverse water that clears it. This time, NOTHING! not a trickle. Obviously, I can't remove the thruhull without hauling the boat, so I'm looking for alternatives. One thought - could the handle on the thruhull be broken and the valve is just not opening? Seems to be doing something... Or, I can get my Lady the semi-fish to dive under and poke at it from the outside with a stick, making sure she doesn't leave the stick in. If that doesn't work, can I use the 1" thruhull currently used for the head sink drain? Either T it, or live without a sink in the head until I haul the boat. Comments? Suggestions?

You should be able to stick a coathanger or something through the open
thru-hull to knock out whatever's blocking it. I'm surprised it's so totally "waterproof". Maybe you have a plastic bag stuck on the outside? -- Keith __ A modest man is usually admired; if people ever hear of him. "Lloyd Sumpter" wrote in message ...

I agree with the advice to snake something through from the inside. |

send her down there with a plunger

Take a dive and see if your underwater thru hull is covered with critters.
chances are that you'll be able to clean it from out side. In case you need to remove the valve from the thru hull pound in a bung to keep the water from coming in. While your down there, check to see if your hull needs to be scraped. Never take the divers word that they did a thorough cleaning with out checking their work.

From: "Lloyd Sumpter" Hi, Finally got that old hose off with a hacksaw and a fair amount of flame. Problem is, I STILL haven't found the blockage! I usually find that if the blockage is in the thruhull, opening the valve with the hose off gives a blast of reverse water that clears it. This time, NOTHING! not a trickle. Obviously, I can't remove the thruhull without hauling the boat, so I'm looking for alternatives. One thought - could the handle on the thruhull be broken and the valve is just not opening? Possible, but doubtful. Seems to be doing something... Or, I can get my Lady the semi-fish to dive under and poke at it from the outside with a stick, I guess that would be up to her. But why not try poking the stick through from the inside? making sure she doesn't leave the stick in. Good idea. If that doesn't work, can I use the 1" thruhull currently used for the head sink drain? Either T it, or live without a sink in the head until I haul the boat. Sorry, lost track of what the plugged thurhull is for. If it's for your head I would not T it. Capt. Bill |

It happened rather suddenly, so I don't think it's barny's at least not initially (might be that there's marine growth in the clog, making it more waterproof) (Go ahead, say it: I'm a big sh*t! :) ) Can't really get at it from the inside: There is the thruhull itself, the valve, an elbow and a hosebarb, all "welded" together with 20 years of corrosion (all bronze). 1/2" above the elbow is a fibreglass seat, and the whole arrangement is accessed via a 8" x 8" port on the side. As I said in another thread, I suspect Catalina put in this fitting and hose BEFORE glassing in the seat! I've tried jamming a bent coathanger in from the inside with no success. Lloyd |

She confirmed what I suspected: she hit something solid, as I did when I was poking with a wire from the inside. The valve is stuck closed, and the lever is broken. There's no way I'm messing with this while it's in the water (I can just see me reefing on a 2-ft pipewrench to try to get the fitting free and cracking the thruhull itself...). So, I "closed" the valve and capped the fitting, then used the sink thruhull (3/4") for the holding tank outlet. Not too big a stretch: the macerator outlet is 1". I converted the outlet hose from 1 1/2" to 1" as well, to reduce the backwash when the pump stops. I figure if it has to go through a foot of 1" hose, why not 10 ft? I'll make do with the smaller thruhull until I haul the boat, then "get serious" with the bigger one. Lloyd Sumpter "Far Cove" Catalina 36: now with (working!) 35 gal holding tank! |

Do you have someplace local that will let you do a haul & hold? If you have all the parts and supplies in hand (including a new thruhull) you should be able to fix it in the slings. Buy every part you can think of -- heck buy two -- and return what you don't use. I would suggest not putting off a haul -- if the seacock is as knackered as you describe, what else is about to let go? dave |

Well Lloyd since you've made your decision. Then replace every thru hull
when you pull your boat. 20 years is a long time for bronze. I would suspect that after 20 years the clog you are talking about caused by galvanic action. Jack "Lloyd Sumpter" wrote in message ...
