I was introduced to this infamous pipe 3 years ago when a supply line
broke on my water heater. I learned the whole story about this pipe
and subsequent law suits, all of which I have apparently missed. Now I
have 2 small drip leaks from a Quest T-connection in my crawlspace. I
have large buckets catching the water until the plumber gets here on
Mon.

Question:
A local plumber has offered to repipe my waterlines for $2500. I will
then get the drywall repaired myself.

Another plumber said his company would to it for "about" $2000.

A contractor friend of my sister said he could have his plumber do the
repipe and a sheetrock contractor repair the drywall for $2750.
Finally another local plumber who's coming on Mon said he needs to
evaluate things but proposes I could just replace every connection
like Ts and valves, since that's where most of the leaks occur. This
house was built in 1986.
Any suggestions or comments would be appreciated.
