I have a condo where the adjacent buildings have all had slab and wall leaks within last year. They have varied between PEX repiping or epoxy relining. Obviously the epoxy would be a less damaging to the unit, but I have heard very conflicting opinions on the potential for creating further leaks during the sandblasting cleaning, or that the epoxy would cause restrictions to flow at ells and tees. I would appreciate input from anyone who has experience with these issues. Thank you

You're talking about the drain pipes, right?
And what has been the cause of the failures? Simple old age, corrosion, cracks in the slab?
Code Approvals?
I didn't know there were any PEX products intended for use with sewage / drain lines.
In general, I have a bias against "quick fixes." Whatever broke the pipes the first time will do so again.
PEX, for water supply, is more than just another material. It's a whole new way to plumb a house.
Sandblasting? Are these pipes exposed? Is the coating applied to the outside of the pipes? Sounds pretty hokey.
PEX recipe vs Epoxy lining
I apologize for lack of specifics. I am discussing the water supply system in the slab and walls of a condo.
According to websites, the commercial & military have used this technique for years with success. Epoxy lining of waste & sewage lines has been successful & economical for a number of years. My concern is that there might be a reduction of flow at ells or tees in 1/2" lines.
Does anyone, consumer or plumber, have any knowledgeable input on the two variations?? Thank you for answers.
