So is the whole building made with the same crappy metal pipes? That's a disaster waiting to happen. Flooding can also start electrical fires.l69norm wrote: ↑ There are pretty stringent flammability/ smoke spread requirements in the building code for any plastic based construction materials used in high rise construction (non combustible construction)
22.214.171.124. Combustible Piping Materials
(1) Except as permitted by Clause 126.96.36.199.(1)(d) , Sentences (2) and (3), and Article 188.8.131.52., combustible piping and tubing and associated adhesives are permitted to be used in a building required to be of noncombustible construction provided that, except when concealed in a wall or concrete floor slab, they,
(a) have a flame-spread rating not more than 25, and
(b) if used in a building described in Subsection 3.2.6., have a smoke developed classification not more than 50.
184.108.40.206. Minor Combustible Components
(1) The following minor combustible components are permitted in a building required to be of noncombustible construction:
(b) mastics and caulking materials applied to provide flexible seals between the major components of exterior wall construction,
(c) fire stop materials conforming to Sentence 220.127.116.11.(1) and Article 18.104.22.168.,
(d) tubing for pneumatic controls provided it has an outside diameter not more than 10mm,
(e) adhesives, vapour barriers and sheathing papers,
(f) electrical outlet and junction boxes,
(g) wood blocking within wall assemblies intended for the attachment of handrails, fixtures, and similar items mounted on the surface of the wall, and
(h) similar minor components.
It wouldn't be cheap, but they could make that pipe out of PEEK, which is good enough for aerospace flammability ratings.
