Hey all, I recently made some major and much needed changes to my water production system in an effort to make rekindling of the hobby easier. One of the changes i made was hooking up a recirculating pump which also serves as a spare backup for my display. I use this pump for mixing as well as pumping water directly to my tank via 3/4" schedule 20 pvc pipe ran through my attic. The cold of winter was an overlooked aspect. I plan to wrap it up with foam refrigant insulation to minimize temperature drop but i'm not sure how the glue joints will handle the sudden temperature change. Temperatures in sw ohio get as low as -15F a few days a year but the average winter day is 20F or above. I'm sure the attic temperature is 10-15 degrees above outside. The attic cycles below and above freezing pretty frequently. Would it be safe to run 80 degree water through this pipe on a day the attic is above freezing?I could suck room temp air through the pipe with a vacuum or use a hair dryer on low to warm up the pipe before sending water through. Thoughts?
