bulkhead

Drilled a 45mm hole for a 1 inch bulkhead and I’m noticing only now that so many things cater to 1/2 in and 3/4 in bulkheads. I’m not a fan of the idea of using a reducer, could I just fit a 3/4 in bulkhead into the 45mm hole?

Bought a return pump that has a 1” nozzle and drilled my tank glass for a 1” bulkhead. I don’t really know what to do next, I know I have to get a return line set up but for some reason I am finding it difficult to find a return line that screws into a 1” bulkhead. Am I misunderstanding something?

I have a 90 gallon aquarium that came with a built in overflow in the left corner. I removed it a while ago. I am trying to find a replacement overflow, there are holes drilled in the bottom that I would like to be able to use if possible. Does anyone know how to make this work out? Dimensions...

So.....I drilled my tank, 2 over flows (only one in the photo) a centre return, but got trigger happy with the drill and added a 1/2 inch drainage bulkhead to make water changes easier! Which is the one at the bottom of the tank with strainer. Im now a little worried that this was a bad idea...

Does anyone have recommendations on where to get a 1/4” bulkhead push connector that is water seal tight? I need a few of these for my mixing station. https://www.bulkreefsupply.com/1-4-push-connect-bulkhead-tank-adapter.html

Let the larger bulkhead dry and re tightened but it comes loose quite easily when the pipe moves. Should I attempt to seal it from the bottom with aquarium sealant? Should I replace the bulkhead completely with a schedule 80? If I go the latter route, would it be worth to remove the ball valves...

My bulkhead is the wrong size and I might not enlarge it... I was wondering if a 3/4 drain is enough ? I also need to mention that if I go this route, the 3/4 drain expands to 1" right after the bulkhead since he rest of the plumbing is 1"..

My plumbing is already 1" for the drain line and emergency line but I bought a new aquarium, custom made and I accidently told the guy I wanted 1 1/5" Holes for the drains.... Now I have to go with 3/4 bulkhead and then use a reducer to open back up to an inch... Unless someone knows where I can...

Hello everyone, I need some guidance here. I have a 30G DT with a 10G Sump I have just finished setting up. I was going to use a HOB overflow but have heard horror stories and with my work schedule I DO NOT want to risk a flood. So I will be pulling most of the water out my tank and moving live...

Hello! I have a bulkhead that is leaking a bit and I am looking to 3D print a tool to better tighten it. I have a 32mm bulkhead from Fijicube and it is branded as a 32mm Flowcolour bulkhead. The dimensions I found on Aliexpress seem to indicate that the male "nut" portion is 52mm wide. Can...

I am planning on setting up a Cor-15 with a 1” return line to my tank. Should I be using 1 or 2 return bulkheads and are there any differences that I would notice if I only have 1 return outlet?

For my 25 gallon nano tank, I will have a 5 gallon Home Depot bucket to hold RODI water to feed my auto top off system. I’m using the Smart Nano ATO system, which uses a 1/4” tube to feed the pump. Do I need to bother with a bulkhead for the tube running into the bucket, or can I just punch a...

Hi, I have a drilled 40 gallon with a bulkhead like this one: I wanted to do put a pvc T in the back of the bulkhead but I couldn’t find one that fit so I’ll just use the fitting that came with it. Would it help the flow if I drilled a hole and added an airline tubing in the top like this? I...

The gasket for the return pump sucks and I’m planning On replacing the pump itself and want to redo that bulkhead as well. I think that’s what it’s called. basically what size bulkhead will I need for this hole

Hello friends, Last night during a water change we noticed a leak coming from the return tubing on our 160 gal mixed reef tank in our school. When we took a look, it was actually coming from the tank-bulkhead connection. We were able to wiggle it for it to stop leaking, but of course we want to...

Good evening everyone! I am building a budget sump setup for a 75 gallon tank. I found this ADHI sump at my LFS for $50, but it didn't come with bulkheads. Does anyone know where to get them and what sizes they may be? Also looking to plug the hole on the bottom with something as I will be...

Is it a rule to glue The PVC to the sump bulkhead on the top side? is there any pros and cons? And what about the bottoms side

Hello Everyone, I'm opening a fish store and have been building my custom acrylic tanks for my store and I want to make sure my plumbing is rock solid to prevent issues in the future. I'm looking for a simple system to run nothing super fancy. My tanks are set up on metal racks and will be...

I've been looking all over for information on this, but how is everyone running their sump return? I mean, what size and type of bulkhead are you using, and what plumbing are you using in the tank to direct flow and the such? I'm using 1 1/4 inch pipe from the DT to the sump in a Bean Animal...

Installing a 120g with 3 1” bulkheads on the bottom of the tank(center interior overflow). Don’t want to drill thru hardwood floors. Am going to run flex PVC throught the back of the stand, through wall, down the cavity, back through the floor joist into the basement. (~15’ run to sump from...
