What damage does glycol do to CPVC? And is the damage visible? Cracks,
pitting or does it fail all at once, leading to extensive water damage?
There is a sign stating the attic has plastic pipe. Can I flush the system
with water several times, and then fill it with glycerin?
Part of the attic is flat, with insulation batts on top of the plastic pipe.
Those areas can be tented with sheet plastic and the batts layed over the
pipe. Part of the attic has a cathedral ceiling, with the pipe hidden in
the joist spaces, I do not know if it is 2 x 4 or 4 x 6 rafters. I suppose
using spray foam insulation on top of the plastic pipe is a violation of the
listing. Can I use pink or blue solid insulation?

Subject: copper pipe vs CPVC
One of our group homes has leaking copper pipe. The owner told me their
experience is to replace the copper with CPVC. I like that, faster and
easier for us. But, do I need to get the system re-engineered when changing
to CPVC? Can I just replace size for like size?
The system is 20+ years old so I am going to propose new sprinklers.
Besides, some of the heads are corroded and some have paint on them.
We will also provide a means to test the antifreeze, at present there is no
way to test the solution.
I am going to exclude sheet rock and painting from the job.
