Intake and outflow valves

[ukrsindicat]

Good morning everyone!

My head intake and outboard hull fittings have no valves. I guess previous owner, believed in luck and his plumbing skills to keep the boat afloat.
Well, its time to get something done about it.
I am know that I need 90 degree ball valves. I was planning on diving under and pushing two Tru Plug cones in the intake and outflow of my hull fittings to prevent water from getting in while I am working out it. However, I am not sure how to glue those ball fittings on. What materials should I use? What precautions to take, etc.

Any help would be appreciated!
Here are photos of the current set up

Might need more information in order to provide any help. What is the picture? Is that hose clamped to a fiberglass tube that goes out the bottom of the boat? So I guess you do not have a real thru-hull. If that is the case I would be hauling the boat. Then I would cut off that tube flush with the hull and install a real bronze thru-hull. To that I would attach a seacock for the head input. Is the output also below the waterline and done the same way?

P.S. maybe that tube is above the waterline so the P.O. thought it was safe.

I am with Ed on this.

You may want to consider having the boat pulled and install new thru hull fittings. You want to be sure that they have backers between the hull and the ball valve/seacocks. You also need to be sure that they are bronze (not brass).

Personally I would have new "virgin" holes drilled thru the hull and abandon (fill the old holes) but that is up to you and/or whom ever does the work.

I think you making a good move to be proactive with this before something happens.

It appears that these are above the waterline so that may be why no one ever did anything about them.

From the photos, it appears you have standpipes

Those are quite common on houseboats (floating mobile home a barge hull) that have bilges deep enough to be "basements," but I've never seen them on a sailboat before. I suspect that a PO decided it was a way to eliminate seacock maintenance...a novel idea, but not a good one!

I agree with Steve..the boat needs to come out and have proper thru-hulls and seacocks installed.

But first, there are possible changes in the plumbing that could allow you to eliminate one of the thru-hulls altogether....see the discussion in this forum about teeing the head intake line into the head sink drain line. And there may be other changes you'll want to make. So let's review the whole system before you have any work done.

Yuriy, There were a couple of boat builders that actually built the boats like this. You really need to haul the boat and get rid of this and install seacocks. If the locations is bad, glass these in and relocate the valves, if the location is OK, do a good professional job of installing new valves. Chuck

Below is a picture of the system you should have below the waterline.
