I'm in the process of moving my laundry area. For the plumbing we decided to use PEX. Unfortunately I have been unable to properly seal the PEX tubing to the fittings on the final fixtures- they continue to leak with a slow drip. What do I need to do to get these to seal.
We tried two different crimpers, thinking that maybe the first one was out of adjustment, but that didn't fix anything. We removed the first set of rings (using a dremel) and crimped on a new set, but the drip continued. We wrapped the hot water fitting with some silicone tape, but the water keeps seeping through.
Maybe I should replace the brass fittings on the faucets. Other than that I'm out of ideas. What should I try next
