    What size bulkhead and return should i use on a 15 gallon column reef tank ?

    Bulk Reef Supply Hi Ricky,
    The size of the bulkhead is mostly dictated by the amount of flow you plan to run through it. Given how tiny the tank is though I would imagine your not going to be running 500 gallons per hour through it. Assuming your not running more then 150gph a 1/2" bulkhead should be plenty fine.

  • by Christian on September 12, 2013, @3:28 AM

    Ok i know this is a stupid question , but i just don't want to order the wrong ones. I have two tanks with herbie drains of 1.5" and 1" returns. The hole on my tanks are however 2 1/4" for the 1.5" drains and 1 3/4" for my 1" returns. So which bulkheads size do i choose, the size of the pipes i'm going to use, 1.5" and 1", or the size of the holes in the tank. I'm using the schedule 80. Thanks you

    Bulk Reef Supply Hey Christian,
    The big thing you want to focus on if your tank is already drilled is the size of the holes. A 1.5" bulkhead refers to the size of the pipe that will be used but you can compare the installation hole size to the holes you have.

    A 1.5" ABS bulkhead requires an installation hold size of 2.32" which is most likely what your larger hole is but worth double checking.

    The 1" ABS bulkhead requires an installation hole size of 1.65" so if you have a 1.75" hole you are all set there!

    Here is one type of the ABS bulkheads.

    It is not 100% clear from the pictures. Please confirm that the INSIDE of the bulkhead through tube is threaded on BOTH the inflow (flange in tank) AND the outflow (nut side).
    Thanks

    Bulk Reef Supply Hi Robert,
    In this bulkhead (the thread x thread version) both sides of the bulkheads have female threads.

    Hey brs
    I have some sc 80 pvc the hole is 1" but the out side is 1 1/4" im looking for a bulk head that would fit this pipe and did't see it on the site do you have one that would fit this size in sc 80 pvc?

    Thanks mat

    Bulk Reef Supply Hi Mathew,
    It may sound strange but you never want to use a tape measure with the diameter of plumbing parts as it will only lead you to problems. Do you know what size the pipe was sold/labeled as? Pipe is measure in nominal sizes, so a pipe labeled as 1" will be compatible and fit with all other 1" pipes and fitting (sch40, sch80, etc) but if you actually measure the pipe or fittings you won't find an actual dimension that actually measures 1", it will vary depending on the type of pipe, fittings, etc. It is likely that if you measured it at a little over 1.25" it is most likely 1" nominal pipe size (the OD would measure 1.315").

    I am ready to drill my holes in my 125 gallon glass tank. I want to use the 'Bulkhead Schedule 80 Thread x Thread' but don't know what size I should use for my tank. what size would you suggest?

    Bulk Reef Supply Hi Todd,
    Most folks with a 125 would use 1" bulkheads for the drain(s). For the return flow back to the tank I would just use whatever size matches your return pump (ie if your return pump uses 3/4" pipe, just use a 3/4" bulkhead) that will save you from having to adapt it or anything like that.

  • by kelly on January 12, 2014, @9:45 AM

    I have a drilled overflow with hole sizes 1.5" and 1.75". I looks like I should go with the ABS bulkhead sizes of 3/4" and 1" instead of the SCH 80 sizes of 1/2" and 3/4". I would rather use SCH 80 but the ABS sizes are closer to my openings and I won't have to sacrifice flow. Am I correct in my evaluation?

    Bulk Reef Supply Hi Kelly,
    That would be my suggestion as well. Tanks that are already drilled for bulkheads are almost always drilled with ABS bulkheads in mind.

  • Well Made Bulk Heads By Nate on 1/6/2015

    These bulk heads are heavy duty and come with a nice thick gasket. Overall I'm really pleased to have the peace of mind that one of my bulk heads isn't likely to fail.
  • heavy duty By Claude on 12/29/2014

    Heavy duty, don't need to worry about it failing for a long time
  • Well worth it By Marty on 12/8/2014

    Wish I had gone with the schedule 80 in the first place. Had 3/4 ABS and replaced it with the 1/2 inch 80 for my returns. Holds tight right away. Extra thick gasket is nice.
  • Use these. Don't cheap out! By Chris on 9/11/2014

    Very solid. Very very solid. Don't cheap out on the others. You'll end up replacing them with the schedule 80s anyways. I've plumbed a 2 in bulkhead to run a 1.5 in intake on a Reeflo Barracuda. Love the setup.
  • Bullet-proof bulkheads By Pegasus on 5/4/2014

    Anyone who has ever used cheap bulkheads will instantly notice the difference in the Schedule 80 kit. These are built to last, which is something I'd consider an important aspect in the marine hobby. While your plumbing should be supported, there is still some weight against the bulkhead. A cracked bulkhead can spell disaster, so you don't want to skimp on those. A little pricey, but well worth the cost when it comes to peace of mind. Better safe than sorry...
  • Great Quality By Jason R on 2/12/2014

    I ordered two 3/4 bulkheads for my sump. One bulkhead seemed to have excess flashing from mold process that required a bit of triming with an exacto knife and wet sandpaper. But well worth the extra few bucks over standard bulkheads.
  • Great product, Heavy duty. By Grizzly on 12/14/2013

    Great product, Heavy duty.
  • A bad batch? By Brian on 10/14/2013

    I don't even know how to rate this since I know these are usually great and everyone else it happy with them. I am wondering if I got a bad batch of 1" Schedule 80 threaded bulkheads. I have an older 2" that is great never had a problem.
    I recently ordered a 1" to plug a hole in the bottom of my aquarium.
    I could only get the plug to screw in about 1.5 turns on the flange side. On the nut side it went in most of the way. With only 1.5 turn I simply can't trust it to hold water.
    BRS promptly sent me a second as replacement and it was the same. I emailed and someone there said that it is normal. They said it is designed to get tighter as it goes in.. well, that part may be true but I can't imagine it only going in 1.5 turns would be normal.. even with a wrench you can't get these in any further.
    By the way it was not the male part.. I tried other thread while in the hardware store. None seemed to go in properly.
  • Huge By samuel on 7/30/2013

    these things are huge and they are built like a tank. i think that the glass in my tank will break way before these things leak
  • nice beefy quality By michael on 7/4/2013

    Got two of these to use on my returns, tank had a hole pre-drilled for a 1 inch bulkhead by previous owner. I got the sch 80 3/4 fitting to use the 3/4 locline fitting in the same size hole.
  • Heavy duty By Jeff on 5/4/2013

    Very beefy bulkheads. Nice thick gasket. Nice to have when it keeps the water in you tank.
  • Quality By Ryan on 11/14/2012

    These bulkheads are the best of the best, just note that the threads are tapered i found out the hard way and put the fittings on so tight i can't get them back off. I would use some teflon paste or tape if I could get them off just for peace of mind but i don't think it is detrimental.
