Bulkhead questions

it is the diameter of the pipe itself. as far as slip or threaded, i prefer threaded plumbing over slip, simple reason is the slip is glued solid and if you have a problem your going to have to do some cutting and splicing, with threaded you can simply grab a wrench.

 

okay kylie i just called menards because i didnt want to give you bad info, it is the outside diameter, not the inside. so basically you will measure from outside to outside.
a crecent wrench will do fine. you can use your hands but after you tighten it up as much as you can, a 1/4 turn with a wrench cant hurt.

 

You can get by without the loc-line pliers, your'e just gonna have to lean into it a bit. They snap together pretty hard but it can be done

Also, do you need those weird loc line pliers to put loc line together or is it possible just with your hands?
Put them in hot water and then try to put them together.  Also I dont know what he means by threaded piping.  But you will need to proablly glue some of the piping fot the tank.  But you will want to get threaded bulkheads, so you can just tighten them, or if you want to move the tank you can, I think thats what he ment.  Gluing PVC is proablly the easiest thing ever.

 

Loc line pliars: not needed.
And sorry mthomp but Menards gave you bad info, it's the inside dimensions that are the 1" and 3/4". The inside dimension of a 1" pvc is 1", the outside is 1 1/4".
I recommend staying away from bulkheads and getting Uniseal Slip Fittings. They are really easy to install, just put them in the hole and shove the pvc through it and it expands to seal up the hole. They are about the same price as bulkheads too. They are also nice because they help prevent vibrations in the plumbing. They are rubber and absorb a lot of the shock. You can always shove the pvc in a little farther or pull it out more after it's installed. I highly recommend these. HERE IS THE LINK TO THE UNISEALS.
HERE is another great site with slip fittings(along with hole size chart), bulkheads, and loc line fittings.
Good luck

I would just go to Theisen's and buy bulkheads there. I know I have made a couple responses regarding that recently (although I don't think any were a response to Kylie's thread(s) ). They sell sch80 but I believe only ThreadxThread. Price are cheaper than the above link as well.

 

Adam those are kinda cool, are you using those? Bela I don't know if there is a Theisens out that way, but if not bulkreefsupply.com, ships super fast, and has awesome prices.

 

Always. I used to work at a plastic manufacturing plant back home before I moved for school and we had every size bulkhead available. My brother still works there so I can still get free bulkheads if I needed them, but I would rather pay the money for these slip fittings than get free bulkheads any day.

 

I have never heard of people really using uniseals on tanks or sumps and don't really see an advantage to them over bulkheads. I have never had a problem with vibration in any of my plumbing either. Personally I like the idea of having a hard plastic fitting then a soft rubber piece holding a bunch of saltwater and thousands of dollars in livestock. Just my .02 cents

 

Ya threaded is the way to go if you want to ever re-use them. I believe all mine currently are threaded.

 

Hung should know what hole saw to use is my guess, I have heard he has drilled quite a few tanks. Just tell him what size bulkhead you are using, I'm guess that you are using a 1 inch pipe so he will need to drill it with a 1 1/2 inch hole saw because to get close to their measurement you would need something like a 1 2/3 which isn't made. It says for the uniseals to use a 1.75/44mm hole saw, which should be the same for a normal bulkhead.

 

bulk reef supply website for holesaws/bulkheads can give you a pretty good idea what size holesaw would be needed. The holesaws come in almost any size metric or english
