I'm looking to replace some copper pipe with PEX. The online debate seems heated, although local plumbers I've talked to seem indifferent about the particulars, just praising PEX in general vs. copper.
Some of the online debate around cinch clamps involves anecdotes about them failing a small percentage of the time. For example, it was mentioned in this question. Given the low cost of cinch clamps and ease of application, would it be a good idea to double up on clamps on each fitting? Any reason this wouldn't be cheap insurance?
