I guess this should be a basic question but I am lost for and explaination. My tanks have REE#s on them from like 94-99. Is this number a reference to a proceedural document or is it a value to use in a standard equation. Such as the # is the immediate expansion recovery amount to pass. expands 200 units and when vented it must be able to recover 198 of the 200 units if the ree is a 99. Is it an actual limit of some sorts? I ask because my hydroer says he doesnt do + hydro's because he doesnt have the documents to do it. If i am not mistaken the name is on the tank depends on the ree value. faber-faber, seaperls-faber, XS-faber. Ie al lp95's but different REE numbers.
Thanks
