Water leak...replace everything
My house is 50 years old and sits on a concrete slab. A few days ago, I noticed that one of my water pipes burst. I didn't actually see water, but I could hear it clearly.
Brought in a plumber to confirm and they were able to determine that there is a leak in the slab below the master shower. The first plumber quoted me 3100 for rerouting that pipe to the attic. Says it wouldn't require breaking into the slab. Also quoted me 2800 for breaking into the concrete and repairing. I've brought in two other plumbers since, with varying quotes. The lowest was just 1000, but we'd need to contract someone to fix the bathroom (I.e., update).
Okay, so all three plumbers recommended that I go ahead and replace all my plumbing, as once you get one leak (and this one sounds loud), you could get another soon. The quotes for replacing everything were around 7k.
First question. Is this simply a scare tactic or wise advice? Second, the house currently has all copper plumbing. If I did decide on some retrofitting (not just a patch), replace with copper or PEX?
