You actually SHOULD replace the galvanized lines as they completely rust up on the inside. The only other thing that you could do is purge the lines with high pressure air or water. Careful though! You would be taking a risk that a fitting would blow!
Galvanized steel is better for plumbing in a bathroom sink. It lasts a lot longer than PVC.
Stainless steel is much better than galvanized for use as a zip-line.
Depends on what you consider better? If a bladder fails you need to rush out and get a new one if a galvanized tank gets floooded you can drain it and your back in business
Aluminum does not rust.
Definitely the plywood.
Go with the aluminum if you can afford it.
There's really no such thing as a steel wire fence without galvanising. An ungalvanized steel wire fence would rust the first time it rained. Therefore you'd rather have galvanized steel or another option. Yes, galvanized steel wire is better suited for fences instead of non-galvanized steel wire. The reason for this is that the galvanizationn process coats the steel with a zinc coating, making it rust-resistant in the presence of moisture.
Although it is not good to put pressure on the console as long as whatever you're putting on top of it is not to heavy you should be fine. Although it would be safer if you put pressure on the box shaped 360, if you have an x shaped 360 i would suggest putting a thin board between the two to better balance were the pressure is put
Depends on local codes and the PH of the water
You will likely be significantly wealthier if you are married to a Broadway producer, but increased wealth will not make your life or marriage better. A good marriage is based on love and trust, and if you find that with a plumber, that is the far better marriage.
Yes, it's better pipe.
It depends on what you want to do with it. Galvanisation usually involves zinc anyway.
