Default Re: thru hull drain tubes in the floor

if your floor drains are like mine, it was pretty easy to get them out and put new ones back in. i tried to use PVC but didnt like it. i would have had to get new plugs and stuff. so i went ahead with the brass and epoxy and have had no problems or leaks yet. thats been probably 1.5 years ago.

Bush I'm going to have to start paying you for ideas. I would have never thought I could taper the tubes like the way you described. Definitely hit you up when I attempt that. I have to watch a couple of old mcgyver episodes to gain some confidence first. LOL

In reference to Greno's qoute. I do have a major problem when those floor drains are unpluged. If your maintaining your station and you walk to one side of the boat the drain hole in the floor drops below the water line and begins to pour onto the deck. I always thought that was kind of a weird reaction if they weren't meant to be plugged all the time.

has anyone else had the flooding problem with the drain dropping below the water line when you walk to one side of the boat?

Yo, Avian, Common problem. Couple of solutions include adding 2 1" drain plugs to the mix or considering the time tested "vortex" concept.

Here's a link to FELLOW-SHIP's "vortex" creation also known as a flapper valve or a duck bill valve.

There you'll see also CSickNick's more modern creation (I think he used bronze and a check valve) and a really good discussion. Note the dates of the posts to give you an idea of how to use the search engine should you need to refer to them again...

. . . I can't imagine scuppers that run through the bottom work all that well either. Eric
That's because your missing one small but important detail. There are small wedges attached to the hull just in front of the scupper tubes which create SIGNIFICANT suction. It pulls the water out much faster than just depending on gravity!

I think I had temporarily removed them for better access when flaring the end of tube, so that's why you didn't see them in photos in my old post.


Here's a picture

Help? Go to the search function and type in self bail scuppers Then check older than 1 month. Next take your laptop and sit on the can for the next few hours reading and looking at pictures [img]/forum/images/graemlins/tongue.gif[/img]

So does everyone have to plug the scupper holes with these? I have a straight inboard 75' and was hopeing that when I redid the floor with composite material and checked the foam that something would have a sign of being waterlogged bad to explain why the drains flood?... I
