I just noticed that an elbow pipe under the sink had corroded through with a leak at the first elbow and needs replacing. I temporarily fixed it with some flex tape and I need to find out what replacement pipe I need to order from Amazon. Should I replace with a brass pipe or will PVC do fine as well?
What kind of pipe is that - copper? Brass? What do you call those tightening sleeve rings on it so that I know what to order?
What caused the corrosion at the elbow- are the big U pipes at the bottom brass? If it's a mixture of copper and brass, it because it mixes copper with brass?
I noticed some white spotting on the longer elbow that the first elbow is connected to - should that be replaced as well? Will it corrode too? It seems 5” tall is that a standard size or would I have to get it cut? I’m at home with no access to outside stores.
Is 12cm circumference == to 1 1/2 inch pipe?
