Through Hull Issue

(1/2) > >>

Valor:
Hey Everyone.

Hope someone can help me out with a problem I am having with a through hull fitting. The Starboard side through hull in which the cockpit scupper is connected to is completely seized. I have loosened the 2 nuts on the back side of the fitting applied PB Blaster for the past few day and I gingerly tried to persuade it with a 3 foot pipe, tap it with a hammer. Nothing. Is there a trick to these things? I was told if you take the 2 nuts off of the back, the entire valve body should come apart. Can someone help me out here?

What you have there is a Wilcox & Crittenden through hull. It is entirely made of bronze, properly maintained it will last forever.
The shut off handle is connected to the through hull valve, which is shaped like a cone.
 
Do not attempt to fix it while in the water.
Once hauled out I would do this:
1. Remove deck scupper hose.
2 Remove the nut on the side of the scupper
3. Try to get WD40 etc in between the valve and the main body and wait.
4 If that does not work, heat the main body with a propane torch. The old lube sometimes hardens up.
5 If that does not work remove the unit from the boat. Unscrew from the outside. There are two flanges on the inside of the outside fitting.
6 Once on a bench heat and wack( use wood to protect the valve stem)the end of the valve stem.

Good Luck

Agreed! You will soon find out if you are one of either two camps-

Keep the old WC bronze tapered cone seacocks and grease them every year or so FOREVER

OR- Install Chinese ball valves that don't leak for five years and then need replacement.

I've have good luck with the old Bronze cocks. I pull the cones out and clean and grease them every year or so.
I use a piece of 400 grade sandpaper wrapped around the cone and loosely turn it in the housing. Reverse and clean the cone...

You'll find the cast nuts not exactly metric or SAE.... I ground a couple of cheap wrenches to fit.

This year after an afternoon on my knees I was calculating my sailing lifespan VS the cost/life of ball valves.

Once finished I was glad I had the old ones back shipshape.

For years I used trailer grease with OK results. now I use a water(proof) green grease- Greengrease.net

Rusty Pelican:
WC made their own threads, it's called the Chrittenden thread.
The reason I know this is because the deck fill covers are from WC with the WC thread too.. I lost one overboard, no deck fill cover fits.
I did not want to replace my water deck fill hose.

Luckily, I found a used WC fuel filler at a shipyard.

Alma:
Yes me too. Funny the deck fill caps do not float! It is the first thing I look for on a salvage boat...
