I’m finishing my trailer build, I’m repurposing 2x 55-gallong poly drums. One as a buffer for my 5.5/3k machine, the other a SH tank. I purchased a chemical drum siphon pump with 2" threads that I’m mounting to the SH drum via an M64/2" thread adapter in this photo, for times I want to pump some SH into a bucket or pump sprayer or something from the larger tank.
I’ve searched and have not yet found anything adapting these Buttress thread plugs and openings that came with the drums to use in lieu of drilling more holes for bulkhead connectors in order to install a Hudson float valve…
(A 2-gallon bucket rim and threaded lid fit perfectly on the space on the top of the drum as a larger opening to install and access the valve.)
…I’m curious if I can knockout the center of these plugs and install a float valve through it adapting the 3/4" threads in the plug to have the float valve beneath in the drum, and a 3/4" male 90º poly elbow with a 3/4" hose barb coming out of the top of the plug that would feed from the supply hose reel. You can see the 3/4" threads in the center of the plastic Buttress plug pictured here, and here’s a photo of the M64/Buttress to 2-inch threaded adapter I’m using for the siphon pump, but I’m not sure how I could use another one of these to adapt down to the connections necessary for the float valve install either.
FWIW, I am planning to use the other plug by threading a 90º poly elbow to those threads in the center, and that will be the connection for the bypass line from the unloader back to the tank.
Anybody done this and I just failed to input the correct search terms? Like I said if it’s too much of an ordeal I can just install a typical bulkhead fitting for the float valve in some of the leftover space on the top of the drum, since I’ll have to do the same near the base anyway, but just trying to simplify this and use the holes already in the drum if I can.
