sprinkler pipe question

[cda]

The pipe was installed before the spray proofing was applied and notice that they covered the sprinkler pipes.

Bingo was his name

I'd have to agree with my friend FM WB....we would be concerned with sprinkler head overspray... also remember...the hangers are rated for the water, pipe, ....plus a "pipe fitter" of 250 pounds.....so make sure your good....

I had a similar situation this year at a four story assisted living. They sprayed some steel in the attic without protecting the sprinkler piping but the heads looked clean. I asked the installer about it and he just said "you want to talk to the site foreman". When questioning him I was told not to worry he personally supervised the cleaning of each head with a toothbrush. I told him all the heads in these areas would need to be replaced and that I wanted to see the old heads saved in a box. This would of been about fifteen heads. The sprinkler installer later told me that they originally didn't want to pay them to protect the heads from the fire treatment or for the new heads after they were damaged.

When I came back the installer showed me a box of about 140 heads to be discarded. He explained that they again did not want to pay the sprinkler installer extra for removing the damaged heads so they had some laborers remove the heads. The laborers were confused about what heads to remove so they remove every head in the attic and put it in the box. Since damaged heads could not be identified all the attic heads had to be replaced. All for not having the sprinkler company protect thier piping and heads in the first place.

Love stories like that

For follow up I might have wrote that since a sprinkler company did not replace the heads, a sprinkler company needs to go back and check each one to assure it was installed per 13.

The sprinkler company installed the new heads they just didn't remove the old ones. A lot bigger bill.
