Default Bulkhead Question

Sorry if this has already been asked, I haven't found an answer in my searches though. I'm going to drill my tank for water drainage, and I'm not sure which bulkhead to buy. I already have a 5/8" diamond hole saw, so what size bulkhead do I need to fit that size hole?

Here's the one I'm thinking of, I'm just not sure which size to order it in. I'm guessing 1/2"? Just want to be sure!

It says in the description that the 1/2" needs and 1 1/8" hole. I really don't know of any bulkhead that is that small.

That 1/2" bulkhead requires a 1 1/8" hole. About the only bulkhead fitting that will fit a 5/8" hole will be the bulkheads that Marty sells at MistKing. It will use his 1/4" hose as a drain hose.
Bulkheads typically require a much bigger hole than it's actual rated size.

Okay, thanks for the help guys!

So is this the MistKing one you're talking about Doug?

Leads me to another question... will this size hole even be sufficient for drainage?

Something to check-out...jehmco.com...they have some miniature bulkhead fittings there that only require a 5/16" hole...there used for airline ...maybe that could be used for drainage?...

Yes it is. It would work for drainage as long as you use appropriate screen layers so your water isn't full of muck. It could plug easier if there is stuff floating around in there.

Okay good! I didn't want to have to purchase another drill bit.

If the drain hole does get plugged up, can you easily unplug it from the outside of the tank?

Look at the picture on your link. See the small black collar on the far left hand side of it? You push that in and pull the hose out. It is a quick disconnect fitting. As long as you can get to the back easily, you can quickly disconnect it without any tools. Pull the hose, poke a stick through the bulkhead and pop a new or the cleaned hose back in.
Of course whatever plugged it will still be in the viv and able to plug it again. Best bet is to use appropriate screening and even lay a bead of silicone around the false bottom so dirt cant fall in around the sides. You can see what I mean by sealing around the false bottom here. http://www.dendroboard.com/forum/mem...tml#post677465

I'm interested in how decided to go about this as well as I'm planning to do the same thing. As far as the false bottom goes I'm putting 3 sides on mine (the back portion will be pushed up against the glass but the sides and front are going to be a little short of the glass so that i can hide the FB with small gravel so that you can only see under the FB from the back of the tank.

I was thinking something like this, but it requires a 1.5" hole which would require me to have the FB way higher than i want

A few posts into this thread http://www.dendroboard.com/forum/par...tml#post694919 I link the parts you would need to do this.

If the bulkhead itself gets plugged up, you could push water through it in the other direction -- either with a pump or by holding a bucket way above the tank and letting it siphon. That wouldn't get the crud out of the bottom, but you'd get your drain back for a while.

you could poke it with a paper clip.... its a 1/4" hole pretty easy to unplug

or just a quick blow on a clean hose would probably unclog it too

Yeah I'm dealing with the same situation. My tanks came to me with a 5/8" hole as a drain hole. So I'm debating on a mistking bulkhead, or the hose with the barbed insert.

My initial thoughts on the barbed insert is to wrap barbs with emery cloth. Then twist back and forth till the barbs are sanded down to the point where it will fit in the the hose and hole. But not sanded too much, to be sure it still has pressure to hold in place and not leak. Then put a bead of silicone around it.

I tried it on a piece that I got at Lowes. If I go this route I will probably use a corner piece since the tank is on a bakers rack. I will use a different kind of barbed piece, not the one in the photos.

Any thoughts?

I use the mistking 5/8" bulkhead and have never had a clog. Two years running no problems.

That's awesome! looks like I will prolly go with the mistking bulkhead.

2 other questions if I may ask-

1-what kind of substrate barrier did you go with? window screen or weed blocker

2-what kind of substrate? ABG mix, or turface?

I use reticulated foam as my drainage layer, no barrier, about 1/2" of turface, topped with about an inch of abg.

thanks for the tip. I'm looking into the reticulated foam. I would actually think it would help prevent it from clogging, plus gives roots more depth. Is there any certain place to find it.

http://www.thefoamfactory.com/opencellfoam/filter.html is where I get it. Someone on here sells it in smaller quantities but I can't remember who.

Hey Duke, do you cut some of the foam for the bulkhead to fit or do you put the bulkhead in backwards so the smaller side is inside the tank? I figure you could do that since you can plug in on both sides.

I put the smaller end in the viv. It seems easier to fix that way if I ever got a leak for some reason though I never have.

I wouldn't recommend this Filter Foam. I ordered a bunch of it, and the first 2 vivariums that I used it in, the water went stagnant.

I had a post about how my tank was stinking not very long ago. Here's the link http://www.dendroboard.com/forum/beg...inky-tank.html

Plus this stuff drains weird. It has to fill to a certain point. Water fills to 1 and 3/4" before it drains, then when it's done the water level is only 1/2" high.

I had a customer over at my place that asked about it, and how it worked. I told him why I got it, and how it drains oddly. I decided to show him, to better understand. I added 2 cups of water, nothing happened. But on the 3rd, it finally started to go. Unfortunately the water had become soo stagnant. It stunk up the whole room. It was horrid! It stunk of sulfur really bad. It was embarrassing. To say the least.

This weekend I grabbed 2 10 gallon tanks, set them up. Now I'm about to transfer the frogs over to them, and fix the false bottom in the big tanks with the egg crate design.

The filter foam method seems to work for some people, and I'm not trying to say that it doesn't. I'm just saying it didn't work for me.
