Not sure what this is?

Hello all.

I have a modular home built in 1977 in Minnesota. I have well water, and septic. I am installing a dishwasher and noticed these torpedo looking things. Off of every supply line (hot and cold) each one is seperate. Have never seen them before, and not sure what they are for.

Those are air chambers that were purchased at a supply house. If they were made on the job they would have caps on them. Take a look at the top of them. There manufactured. We use to bye them by the case. They came in two lengths. If I remember correctly they were available in 6" & 12". It was cheaper to use them in place of a 3/4 x 1/2 x 1/2 with 12" of 3/4 copper and a cap.
