PST hydro

[opie712]

I have two lp85 which I think are actually lp80s and one hp100 that's due for hydro. Do all pst tanks have the special hydro procedure or just the hp tanks?
I can't find the procedure online could someone that has it upload it so I can tape it to the tanks when I take them in for hydro

if the hydro facility doesn't know off the top of their head, go to another hydro facility. too many of these tanks have been failed due to issues with hydro

He seemed like he knew what he was talking about I just aquired the tanks not long ago and don't really know the procedure other than its was different so didn't really know what questions to ask. Thats why I was trying to find the procedure to read over nyself
