small bro ro

[phil bemis]

anybody know if i can use leader ro soap in an old small brother ro that has osmonics membranes?

What do you mean by 'leader soap'?

You need more info. Different membranes need different pH in wash solution.

i got soap from a leader dealer they said ican use it on osmonics membranes the soap is ment for filmtec

You need to know just what you have for membranes. I have an SB ro but instead if the old osmonic membranes, mine has the new filmtec xle4040. I have to use to use the powdered (sani-membrane) soap, which contains no chlorine. The other type of soap(sani-osmos) is a liquid containing chlorine that is used for the hydranautic type membranes. Is that any help?
