    Default Aluminum wash tank?

    Would ro soap react in a bad way with an aluminum turkey fryer used as a wash tank? Per Leader's instructions, I converted a plastic 5 gallon bucket to a wash tank. I am not happy with that setup because I cant get the bulkhead fitting to seal in the bottom without the plastic cracking. My next step would probably be to purchase a wash tank from Ray Gingerich. Dr Tim any thoughts on this?

    I have the mico ro 2 and used a 5 gallon pail and the bulkhead fitting worked fine. I put a little fda food grease on the rubber seal .

    Very bad idea. Aluminum and lye (RO soap) are not compatible. https://www.youtube.com/watch?v=GESJ2YUWRx8

    Aluminum and strong acids, while not quite as bad, are also not a great idea. Even many acidic foods/beverages are packed in non-aluminum or coated-aluminum containers to prevent eating away the metal.

    Dr Tim that's what I figured. I already left a message with Ray. Thanks.
    Western mainer after already having two ro's with dedicated wash tanks I just feel the 5 gallon pail idea is kind of weird I guess.

    My wash tank is the bottom half of a plastic 55 gallon drum. Much thicker than a bucket.

    If the bucket idea is failing it is likely how you are doing it. How do you cut the hole, and is it a good fit for the bulkhead fitting? Are you making the hole in a spot where the thickness is uniform? Sometimes people over tighten a bulkhead fitting and that can tend to push the gasket outward which causes a leak. While one of Ray's tanks will be nicer, try again with another food grade bucket to use until Ray's tank arrives.

    I was able to get a used welded wash tank from Ray last week. I put a thermometer in the side. It works great.20190331_125128.jpg
