Has anyone hooked up a Fol Da Tank under their house?
How did you attach to the bladder?
Fol Da Tanks have a 4" fill opening and I've reached out to them about hooking up a permanent fill tube to it. I don't have my tank yet and I cant get an answer from them about what the thread type is on the opening. I've searched high and low with no luck as to whether or not its NPT, NST (NH), GHT, etc. It would be really nice to order the parts in advance since I am located in Alaska and it takes time for things to get up here.
I am looking to use pvc or abs piping running from outside my house into the crawl space and attaching directly to the tank fill hole.
Anybody have success doing this?

I do not have a bladder tank, but that said I don't see why you couldn't tee the line.... one side of the tee to pump water in, the other side goes to your uses. This is how our cistern is plumbed. Your only issue may be the need for a way to tell when it is full. Our cistern just overflows if we pump too much in.

Ya thats exactly my concern. It being under the house in a crawl space I wouldn’t know when it’s full.

If you get two water meters, you could measure how much is drawn and how much is added. Make sure the difference is never more than the tank's volume.
They're not perfect devices, so you'll occasionally have to audit it.
If you're only filling it when it's empty, then you only need an incoming meter.

Does the bladder have a pressure rating?

From what I'm reading, there would also be a 1.5" female thread ball valve or 2" ball valve with female camlock fitting, which seems to be a firefighting standard.
Why not use this and keep the 4" plugged?
If you rig something to the 4" tube, you'll need an inlet pipe.
