So, you have a tank and you ask, how do I attach the plumbing?  You need a tank connector fitting.  Most tanks are too thin to tap for your plumbing; you need to get a nice deep thread for proper seal.  One of our tank connection fittings can do the trick.  All you need is access to the inside so you can push the gasketed tank connector through the wall (after you drill the holes) and then you secure it from the outside with the included backup plate and nuts or by installing the large included nut (depending on which fitting you choose). You may have to retighten the tank connection fitting from time to time as the gasket compresses.  Note that bulkhead tank connectors with a single large nut are usually have left-hand threads for the installation nut.  They also have a buttress thread so a certain side of the nut must be facing out.  Do not flip it around!


How do I install a tank connector fitting?  After you receive your fitting you will be able to see the hole pattern and drill the hole(s).  Once the hole(s) are drilled in your tank you need access to the inside of the tank to install the tank connector fitting through your hole(s).  Then you will secure the tank connection fitting from the outside of the tank.  To guide it into a remote area of your tank you can put a rope or line through the hole and guide your bulkhead fitting or tank connection fitting down the rope or line.  Make sure to follow the torque specifications and it's extremely important that you use anti-seize on the nuts and studs.
