Antifreeze replacement schedule?
Antifreeze replacement schedule?
(OP)
Is there a specified schedule for antifreeze replacement? A respected colleague swears that antifreeze is to be replaced every 10 years, but can't cite the code. I can't find anything in NFPA 25 stating anything about antifreeze longevity. I have a good number of antifreeze systems to service and am of the opinion that if it tests as adequate, it's good to go, regardless of antifreeze age.
Does anyone know of a specified schedule for antifreeze life?

5.3.4.3.2 If the test results indicate an incorrect freeze point at any point in the system, the system shall be drained, the solution adjusted, and the systems refilled.
5.3.4.3.3 For premixed solutions, the manufacturer's instructions shall be permitted to be used with regard to the number of test points and refill procedure.

TIA 10-2 to NFPA 13 will scare the crap out of you if the antifreeze system is in a R-2 occupancy under the IBC. It essentially says no antifreeze in a group R IBC occupancy. And for good reason.
Stookey, which section of 10-2 is saying that the use of anti freeze not allowed in R???
