Frozen Thru Haul

Probably should be done out of the water, but here goes. They''re probably wilcox crittenden tapered plug valves, which notoriously freeze semi-annually. Tapered wooden plugs (Hamilton Marine, etc.) inserted with a tap from the outside below the waterline will work. So will a piece of flexible plastic or an innertube chunk if you have someone hold it against the through hull intake while you open the valve and "suck" whatever you''re using up against the hull from the outside. But you say they''re frozen. Wooden plug tapped in from outside, then take the valve section off the threaded thru hull, clean the hell out of it, bronze wool, tons of teflon grease and reinstall. Get the plug out by inserting a rod into the open valve, tap the plug out and close the valve quickly. Put the hose back on, double AWAB clamps and you''re good for a couple more weeks. That''s the problem. Once pitted, the old valves freeze up easy. Get new GROCO stainless ball valves with the big, easy to use handles....KW

Frozen Thru Haul

I have a couple of older model bronze thru hauls that have frozen. I am wondering if anyone has experience with a techniques for freeing these in water?? Also,they seem to have a grease fitting on them, and I''m wondering if I can grease them while in the water.
