alextret Posted August 2, 2006 Report Share Posted August 2, 2006 There all sort of technical setups with overflows on the Internet. But I wonder, where do people get bulkheads? I mean those fittings that they stick around the hole, once there is a hole in a tank, to attach tubing. Quote Link to comment Share on other sites More sharing options...
suphew Posted August 2, 2006 Report Share Posted August 2, 2006 Most plumbing shops sell them. I have got them from both Mico and plumbing world before, have even seen them in bunnings. Quote Link to comment Share on other sites More sharing options...

Feelers Posted August 3, 2006 Report Share Posted August 3, 2006 I went into Mico and the guys had never heard of a bulkhead haha! After describing ad nauseum what it did, I eventually found them myself. After having spent litreally 10 minutes describing both what the fitting did and how it works - even a sketch showing the rubber gaskets and eventually an online picture of the fitting, he still didnt get it . "This is what I was looking for... " - "ohh, they use those on water tanks". Uggghh!!!! :roll: SO moral of the story is, these things are reffered to as "hanson fittings" if you are ever unfortunate enough to run into such troubles. My faith in humanity has been forever shaken. Quote Link to comment Share on other sites More sharing options...
alextret Posted August 3, 2006 Author Report Share Posted August 3, 2006 Are you using the following product? Hansen Tank Fitting http://www.hansenproducts.co.nz/products/thread/STF.htm Quote Link to comment Share on other sites More sharing options...
KP Posted August 3, 2006 Report Share Posted August 3, 2006 most of us use these ... http://www.hansenproducts.co.nz/product ... /SFTFT.htm Quote Link to comment Share on other sites More sharing options...
chimera Posted August 3, 2006 Report Share Posted August 3, 2006 bulkheads seems to be an american term, hence why most non-fish-geeks have not heard of the term tank valves or hansen fittings as mentioned above is most common, and KP's link above are the better choice Quote Link to comment Share on other sites More sharing options...
alextret Posted August 3, 2006 Author Report Share Posted August 3, 2006 Thank you very much for the info. >most of us use these ... What is the most commonly used diameter (for fish tank overflow)? Would it be something like SFTFT40 40mm (at http://www.hansenproducts.co.nz/product ... /SFTFT.htm) ? Quote Link to comment Share on other sites More sharing options...
suphew Posted August 3, 2006 Report Share Posted August 3, 2006 Just depends on your tank size, pump size and the size of the rest of your plumbing. My over flow is 40mm, my closed loops are 32mm, but these are pretty big sizes. Quote Link to comment Share on other sites More sharing options...

suphew Posted August 3, 2006 Report Share Posted August 3, 2006 Just out of interest, why is that style a better choice? Because they are screw fit rather than push fit, screw fit are less likely to leak or suffer salt creap. Also pressure fittings connect directly to them so you dont have to change from push fit to treads to attach pumps etc Quote Link to comment Share on other sites More sharing options...
